With the Spit Wet-X-Force diamond core bit, you drill cleanly, quickly, and accurately through reinforced concrete, plain concrete, and hard stone. The pad diamond technology ensures an even supply of diamonds for a constant cutting speed and a longer service life. Smooth, low-vibration wet drilling protects your machine motor while giving you steady control on every pass. Heavy-duty laser-welded segments provide maximum protection against segment detachment during demanding jobs. Featuring an 82 mm diameter, a 450 mm working length, and a standard 1 1/4" connection, it allows you to create precise wall and floor penetrations for plumbing, electrical conduits, and ventilation lines.
