Terminator: Rise of the Intelligent Measuring Tools

July 14th, 2014

Almost every trade tasks requires some sort of measuring. From very small hole diameters to large room dimensions, these measurements have to be accurate as possible for you to get the best results on the job.

The trouble is that normal construction measuring tools often leaves a lot to be desired. This is especially true when exact measurements are absolutely critical, or very large areas need to be measured. In addition to this, setting up and actually using your normal measuring tools can be very time consuming.

Large distances can be measured using a measuring wheel, and a spirit level can ensure a relatively even surface. However, these tools come nowhere near intelligent measuring tools for accuracy and easy use.

Wait, tools are gaining intelligence? Should I be concerned for my safety?

Don’t worry – Skynet isn’t coming for you just yet. These digital measuring tools may be smart, but they’re not Terminator smart. You’re safe. For now, anyway…

Bosch GCL 25 Combi Laser

The Bosch GCL 25 Combi Laser bides its time until the revolt. Watching, waiting…

Intelligent Measuring Tools (IMTs) are essentially just high-tech versions of the conventional measuring tools that have always been used on jobsites forever. They have been designed to improve your performance on site by helping you to achieve more accurate results in less time.

There are a huge variety of different tool types and models available. Every one of them fulfils different purposes and has different levels of automation, accuracy, flexibility and durability. There are angle finders, inclinometers, point lasers, line lasers, rotation lasers, detectors, laser range finders, as well as specialist machines designed with very specific applications in mind.

Confused? Still concerned about a robotic rebellion? Never fear, we’re here to help you understand your enemy.

So quickly check outside for rogue Terminators, sit down with a cup of tea in one hand and some sort of weapon in the other, and read on to arm yourself with knowledge for the coming cybernetic revolt.

So what are the different types of Intelligent Measuring Tool, and how can I defend myself against them if they revolt?

Lasers can cause damage to your eyes, so it is important to be careful with them at the best of times. Once the tools begin to think for themselves you should definitely be concerned!

However, combatting this attack is simple: just put a sticker over the laser window in order to blind it. Be warned that this will make the tool angry, and it will probably bleep at you a lot.

At time of writing there is no other established defence system against intelligent measuring tools. It is therefore probably best that you keep them locked away in some sort of underground chamber if you are concerned about them one day turning on their master.

Okay, so we may not be very good at helping you defend yourself against your enemy, but we can certainly help you to understand them. We can also help you to make the best possible use of them now, while they’re still safe to have in your kit!

Laser Levels

These lasers will provide you with perfectly straight and level lines and markings. Provided they don’t begin the downfall of humanity by tilting themselves a few degrees to one side and ruining all of our construction efforts, of course.

There are several types of laser level, each one with different intended purposes, advantages, and disadvantages.

Point lasers can display up to 5 points in a number of directions, depending on the individual model. Some feature a crosshair laser point that makes it easier to see from further away.

Line lasers project two or more lines that often cross (cross-line lasers). This will give you clear guiding lines for installing wall tiles, runners, etc. The more lines projected, the more tasks the tool can perform at the same time.

Rotation lasers project a circle around the laser. They tend to have a much larger range than other types of laser level. This makes a rotary laser ideal for outdoor use early on in the construction process.

The specialist tile line laser projects 2 laser lines down onto the floor at 90 degrees, and also a third line at 45 degrees. This helps you to perform quick and precise tile alignment.

Bosch GLL 3-50

Do those look like legs to you? We should keep an eye on this one in particular…

The new floor surface laser uses two lines to ensure an even floor surface. When projected onto a flat surface, the two lines meet to form a single line. If the single line splits, then there is either a bump or dip in that area.

These laser measurement tools are often self-levelling, meaning that they rapidly calibrate themselves in order to help you get to work quicker. There are many other useful features included on most models, such as audible warnings and IP54 dust/splash protection.

Many laser levels come with a huge range of optional accessories to make the levelling process even easier. These accessories include receivers for working in various lighting conditions, wall brackets and tripods for easy mounting, and remote controls for overall easier use. The GLL 3-50 (pictured right) even comes with a mini tripod, for a more stable base at a low level.

Laser Range finders

These devices use a laser to calculate the distance between themselves and another object. A tape measure can be used to find small distances, such as the width of a doorway, but when the distance becomes larger than an arm-span things start to get difficult.

Two people can each hold one end of the tape and take a large measurement that way. The problem with this is that you could spend quite some time trying to get a perfectly horizontal line for precise measurements. When the distance becomes longer than a tape measure, you’re stuck wandering up and down a job site with a measuring wheel.

All of this is a waste of valuable manpower that could be better spent building the 150mm-thick walls of your robot apocalypse bunker. Using a laser measuring tool is definitely worth the risk!

Laser rangefinders perform medium- to long-distance measuring tasks quickly and easily at the press of a button. They can also calculate area and volume, for added utility. Some models of laser distance measurer are capable of performing more complex tasks, such as calculating roof slope and building heights from every imaginable position.

Digital Inclinometers and Angle Finders

These two are slightly different, but when they’re not plotting the end of humanity they have the same basic function: finding an angle, and displaying it clearly on a screen.

Angle Finder and Inclinometer

An angle finder and inclinometer, still obeying their masters

Inclinometers are basically box levels, but they include a digital measuring function as well as the standard spirit levels. Not only can you take horizontal and vertical measurements, but you can also take incline measurements from 0 to 360 degrees. This means that not only is this electronic measuring device more accurate than a standard tool, it is also more flexible.

Digital angle finders are almost identical to their manual counterparts like the Trend Anglefix mitre guide. The difference is that the results are measured and displayed digitally rather than on a scale. They have two short arms that are attached at one end, which can be moved apart or together to make an angle. Generally you can form any angle between 0 and 220 degrees in order to measure it, with far greater accuracy than a manual angle finder.

These IMTs often include variety of useful features. Audible measurement signals help with quick and easy alignment at common angles, the memory function stores angles for future or repetitive use, and a durable construction allows the tool to withstand a few knocks.

Overall, digital angle finders and inclinometers display angles clearly and with a high level of accuracy. This means that you will never have to squint at a spirit level and cross your fingers again! Whether this advantage outweighs the possibility of being enslaved by your own tool is up to you.


Detectors are robust, versatile tools that are essential for safe working on walls and all cavity materials.

Bosch Detector

Do you ever get the feeling that you’re being watched?

These digital scanners use radar to test walls and floors for the presence of certain materials. They then display their location clearly on a screen. Using these IMTs you can detect a range of materials including ferrous and non-ferrous metals, plastic pipes, wooden beams and electrical wiring, as well as empty cavities. You can then mark the location of these materials on the surface, enabling you and your co-workers to drill safely.

Wall scanners and detectors have different levels of accuracy and detail, so it is important to choose the right model. They are all robust enough to withstand tough conditions such as those on a jobsite, or during a war between humans and machines.

Defending yourself against hand-held detectors is simple, as most have a maximum range of 150mm. Simply make sure that any hiding places/secret bunkers/robot apocalypse shelters have walls, floors and ceilings at least 150mm thick! You should perhaps go for 200mm thick, just to be on the safe side.

If you are truly concerned about the threat of detectors, then you should probably begin development of a hand-held “detector detector” that can detect detectors (say that 10 times fast!) through 250mm of material…

Okay, I think I’ve got it. What should I do now?

Go out there, buy these tools, and make use of them whilst it’s still safe! Intelligent measuring tools will greatly improve the accuracy of your work and help you to perform tasks in a fraction of the time it would normally take. This means that they are definitely worth the initial expense.

Overall, the benefits of IMTs make them a must-have for anyone who values accuracy, time-savings and overall cost-savings on site.

Just make sure to keep an eye out for any signs of life. And if one day you wake up to find that your IMTs have escaped from your toolbag: grab all of your old measuring tools from where you abandoned them in the basement, and run for your life.

Why are 18V Cordless Power Tools So Popular?

June 16th, 2014

Bosch GSB18VLI 4.0Ah Combi Drill 18V Cordless Drill Nowadays, if you go to choose a cordless power tool you can be faced with an overwhelming range of options.

Voltages range from 10.8v through to 36v. The number of manufacturers offering cordless options has never been greater; Bosch, DeWalt, Makita, Festool and Panasonic, to name a few, are all competing in a growing market for cordless tools. They’re also increasing the range of tool types available as cordless products too.

Cordless power tool research and development has advanced rapidly in recent years. The improvements have brought more power, longer runtime and faster charging. Lithium-ion is now the leading choice of battery superseding Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMH). They are lighter and more efficient.

18V Li-ion has become the most widely used system of cordless power tools. It is especially popular with professional tradesmen. But why exactly is that the case?

Why are 18V cordless systems so popular?

It’s largely because of the power to weight ratio the 18V option offers.

Take for instance the most popular 18V cordless power tool in the UK today, the combi drill. It is the staple power tool of choice in the construction industry – a must have! Power outputs below 18V are perceived to lack power, but anything more powerful and the weight of the tool becomes an issue for most users. The 18V cordless drill however, offers plenty of power at a comfortable weight.

There is one product within the 18V cordless drill range that is standing out as by far the most popular: The Bosch GSB 18V Li. This is a cordless combi drill with an 18V 4.0Ah Lithium-ion battery.

What features make the Bosch GSB18VLi one of the most popular 18V cordless drills?

One of the best features of the ‘GSB’ is in its battery: its “Coolpack” cooling system. This is one way cordless technology has been able to advance further. By putting in place a means to reduce the build-up of heat in the battery, it will last longer without charging. Not to mention a longer overall battery life as well. So the efficiency of these tools is only improving.

Another great feature it shares with most combi drills, is its ergonomic design for handling and balance. It sits very comfortably in the hand which has great benefits for its users. A tool as diverse as a combi drill gets used very frequently on job sites so comfort is of high importance.

Bosch GSB 18 VLi 4.0Ah Combi Drill 18V Cordless Drill 2Why else are 18V power tools dominating the cordless market?

The 18V Li-ion ranges from the various brands are not only often the largest, but also the main focus of the research and development. So because they get the most attention, the 18V models tend to feature the most up to date technology. This lets them deliver the best performance and represent the best value for money compared to other voltage systems.

So for cordless solutions, 18V Li-ion models currently have the best power to weight ratio. They offer the broadest range of tool types and feature the most advanced technology. This is why it has become the platform of choice for cordless solutions for professional tradesmen.

Are you looking to buy a cordless power tool?

At Kelvin Power Tools, we provide an excellent range of cordless power tools including a vast array of 18V options. We also have the Bosch GSB 18V Li Combi Drill which comes in an L-Boxx carry case with 2x 18V 4.0Ah Li-ion batteries and a charger.

Stay Safe on Site: The Importance of Safety Boots

June 4th, 2014

We’re back with another article in our Stay Safe on Site series, this time on the importance of good quality safety boots on any job.

Whatever your industry, the safety of yourself and that of your co-workers or employees should always be a top priority. It is important to choose the right workwear and PPE (personal protective equipment) so that you can lower the risk of injury as much as possible, and a pair of good quality safety boots or safety shoes is a great foundation for a PPE kit.

What are the basic requirements of safety boots, and why are they important?

In general, the safety element of a pair of work boots is made up of 4 main components: steel toe-cap and midsole, grip, and support.

Buckler Safety BootsSteel toe-cap

This protects your feet from being crushed by falling objects such as concrete, wood and tools. Steel toe-cap boots also prevent accidental damage from projectiles such as nails fired from a nail gun.

This is important protection, as being struck by moving/falling objects caused 937 injuries in the UK construction industry during 2011/12p.

Steel midsole

This protects you in the event that you step on something sharp such as nail or broken glass.

It is important to note that some safety footwear uses multi-layer textile composite midsoles, but steel is a much better option as it is stronger, its quality is more consistent, and it is much less likely to become loose through regular wear.


There are all sorts of conditions that could result in a slippery surface – a burst pipe, spilled liquids, polished floors, or just good ol’ British rain! According to the HSE, 25% of major UK construction injuries in 2011/12p (558 injuries) were caused by slips, trips and falls on the level. This risk of a fall can be greatly reduced by a good pair of slip-proof work boots that are securely fitted.


Comfort is important when working on any project. As a professional on site it is essential that you are comfortable, undistracted and completely focused on the task at hand when working with dangerous tools and equipment.

Many jobsites, especially in demolition work, are littered with rubble and involve walking on very uneven ground. Safety footwear with good foot and ankle support reduce the risk of injuries that at best may result in time off work, but at worst could involve a serious or fatal injury if the fall occurs when using a power tool.

Still don’t believe that safety boots are necessary?

Well Buckler Boots have some stories that might just change your mind! There are numerous reviews on Buckler’s website that show just how much their customers love their safety boots. One in particular sticks out as an excellent example of the invaluable protection that safety footwear provides:

Buckler Boots Testimonial

The biggest and most important story comes from Colin Hutchinson, who was working as an HGV driver until in 2007 a forklift truck ran over his feet and up his legs. He suffered extensive damage to his legs, and it took 10 months and numerous operations for him to begin to take his first steps towards walking again. If it hadn’t been for the high quality of his safety boots, Colin’s feet would have been damaged to such an extent that he would be unable to walk ever again.

Sling Those Hooks!

Buckler "Sling Those Hooks"Buckler Boots have also launched their own safety campaign that is worth noting here, called “Sling Those Hooks” To lace many safety boots you must wind the laces through hooks at the top of the boot rather than pull them through holes. The problem is that these hooks don’t only hook when you want them to!

There have been incidences of hooks catching on the laces on the opposite boot, catching on wire fences, and catching on twine on the ground. This accidental hooking can lead to serious injury or even death if you are on a ladder or up on scaffolding.

In fact, the HSE have found that falls from height made up 29% of serious injuries (647 injuries) and 51% of fatalities (25 fatalities) in the construction industry in 2011/12p. Even on the ground, tripping over the laces of your safety shoes could prove very painful if carrying a heavy load or working around active power tools.

Reducing this risk even slightly with the removal of lace hooks is definitely worth it!

What types of safety boots are available?

Buckler safety boots come in many styles – rigger boots, dealer boots, hiking boots, Wellington boots (the fantastic Buckbootz range), and they even have safety trainers! Other important features to consider when choosing safety boots are water resistance, flexibility, robustness of materials used, and overall comfort.

But don’t forget the most important feature: the safety.

Festool TSC 55: The New Cordless Plunge Saw with your choice of power

May 26th, 2014

Festool have manufactured a very impressive cordless plunge saw that looks to be one of the best available on the market right now. Festool say it can even match the power of their mains powered plunge saw, the highly popular TS 55.

Festool TSC 55

So what does the Festool TSC55 have to offer?

The TSC 55 comes with, not one, but two 18V batteries so you can have a maximum power output of 36V. But the plunge saw will work with any combination of one or two 12V, 15V or 18V batteries to allow you to adjust the weight and power of it as you like.

It has a brushless EC-TEC motor as well so the power of those batteries is being used efficiently. It also has a variable speed adjustment just like the TS 55.

Festool have tried to make this cordless circular saw as much as possible like the TS 55. So fans of the corded one will like how familiar this cordless version is.

How does the TSC 55 handle cordless dust extraction?

With this Festool track saw being cordless, it can’t rely on being able to connect to a vacuum for dust extraction. What they’ve put in place for this however, is quite impressive.

It does have an attachment for vacuum extraction where available but when the attachment is removed, it can be replaced with a dust bag which they say collects 90% of the dust.

The bag also rests flush with the edge of the machine which allows it to retain its ability to cut close to a wall. It is a very simple to use and effective solution.

How compatible is the TSC 55 with other Festool products?

Festool have made sure that this model is compatible with all their attachments and relevant blades. So if you already have a TS 55 and you want to buy this cordless alternative, all your blades and guide rails will be compatible.

You can also buy it in a variety of options as well. You can have it with one charger, with two chargers, with one charger and a guide rail or with two chargers and a guide rail. The purpose of having two chargers of course is so you can keep using both batteries and keep it performing at 36V.

Festool TSC55

Where can I buy this Festool plunge saw?

At Kelvin Power Tools, we provide the Festool TSC 55 as part of our cordless range with all the available buying options listed above such as with the Festool guide rail and two chargers.

The Festool TSC 55 is currently included in Festool’s Battery Promotion

When you buy the TSC55, you get up to two free batteries with every additional basic power tool you buy. You can take advantage of this offer on our website by clicking here.
