DeWALT DT9590-QZ Sds Plus Extreme Drill Bit 18x450mm, Working Length 400mm

The EXTREME DT9590-QZ from DEWALT is an 18mm x 450mm SDS Plus drill bit with a 400mm working length, featuring the Extreme 2 tip design. The high-grade two-cutter carbide head, with two flanking cutting tips, drills fast and lasts longer. Inside, a Tough Core adds material for strength, and Iron Blast high-speed blasting toughens the bit against breakage. An optimised shank grips firmly for power transfer, the 2-stage helix keeps dust moving out of the hole, and an anchor wear mark signals when to change the bit. Suited to clearance and anchor holes through concrete, masonry, stone and block.
