DeWalt DT90244-QZ 28mm x 152mm EXTREME Tri Flute Drill Bit

DeWalt DT90244-QZ EXTREME Tri-Flute Wood Drill Bit – 28mm x 152mm, Quick-Change Hex

DeWalt DT90244-QZ is an EXTREME tri-flute wood drill bit designed to cut fast, clean holes in timber, with a self-feed screw tip that helps pull the bit through for smoother drilling. With a 28mm diameter and 152mm overall length, it’s a practical choice for trades and installers who want rapid material removal when boring larger holes in wood.

Built around a tri-flute tapered profile and three cutting edges, this DT90244-QZ bit is made to reduce chip build-up and binding, while the 1/4" (6.35mm) quick-change hex shank suits common hex adaptors and quick-change extensions.
