This Bosch 8mm CYL-3 concrete and masonry bit is a straight shank bit with a working length of 90mm. This is a specially-designed Bosch drill bit for concrete working, but it can also be used to drill in masonry, limestone, natural stone and artificial stone.
Bosch CYL-3 concrete bits have a standard 2-cutter construction, and feature a special U-shaped flute that prevents clogging caused by drilling dust. They are very impact- and bend-resistant, which results in a much longer lifetime in concrete compared to other similar bits on the market.
All Bosch drill bits are manufactured to the highest standard (ISO 5468), which creates a robust bit for drilling quality holes.
Bosch offer a standard 1 year warranty with all of their machines, batteries and chargers. You can extend this to a 3 year warranty for power tools or a 2 year warranty for batteries and chargers by registering your product on the Bosch Pro 360 portal here within 4 weeks of purchase.
Note: Due to the nature of their application, accessories and consumables do not have a wear and tear guarantee or warranty. If you are unhappy with your product then you can contact Bosch directly to discuss this.
