In a nutshell
The right choise for
With the Bosch CYL-3 concrete drill bit, you drill fast and accurate 4 mm holes into concrete, masonry, limestone, and natural stone. The durable carbide tip with 2 cutting edges delivers high wear resistance, preventing premature wear in abrasive materials. Thanks to the 2-flute U-shape design, drilling dust and debris are cleared efficiently, significantly reducing friction and heat buildup during operation. Featuring a 40 mm working length and a 75 mm total length, it is ideal for drilling plug holes for indoor assembly and fixture tasks. The 4 mm cylindrical shank mounts securely into any standard three-jaw drill chuck on corded or cordless impact drills.
