In a nutshell
The right choise for
With the Irwin Speedhammer 2-CUT SDS-Plus hammer drill bit, you drill deep holes into concrete, masonry, brickwork, stone blocks, and granite with ease. Featuring a total length of 460 mm and a working length of 400 mm, it reaches through thick walls and cavity structures where standard bits fall short. The self-centring tip prevents wandering on smooth surfaces for an accurate start, while the hardened chrome-vanadium steel body and 2 carbide cutting edges deliver exceptional durability and break resistance. Thanks to the asymmetric flute design, drilling dust is cleared rapidly to prevent clogging and overheating. You get fast progress, precise control, and reliable performance on demanding construction jobs.
