Kelvin Power Tools stock a wide range of hand held circular saws and plunge saws from top brands like Bosch, Festool, Makita, DeWalt and Skil. Most circular saws are designed to cut wood, but with an appropriate blade they can also be used to cut masonry, plastic and metal. They are generally held in the hand when used, but most circular saws can also be mounted to a stand or table to become a table saw.
What makes plunge cut saws different to circular saws is the spring-loaded riving knife, also known as a spacer wedge. Riving knives sit behind the blade, preventing the material being cut from pinching the blade and causing kickback when performing rip cuts. The riving knife has to be removed from circular saws to make plunge cuts, as it prevents the blade from plunging straight down into the material, but on a plunge saw it is spring-loaded. This means that the material pushes it upwards and out of the way when the initial cut is made, but it slips back down and into the cut as the saw moves forwards. This is a valuable safety-enhancing and time-saving feature for anyone who performs plunge cuts on a regular basis, especially rip-cuts. Additionally, plunge saws also feature minor improvements and specific changes of design that make plunge cutting a much easier job.
Important features to consider when choosing your circular saw are weight, cutting depth, the motor and torque, dust extraction, compatible guide rails, blade changing system, and protection of user and material.
