1/4" x 4" Premium 2 Cutter Percussion Carbide Drill Bit DW5224B25-SBD

Dewalt's 1/4-in x 4-in Premium Percussion Masonry Drill Bit (DW5224B25-SBD) is a professional-grade solution designed for high-efficiency drilling in masonry, concrete, rock, and artificial stone. This bit features a Rock Carbide tip that maximizes surface contact for a longer tool life and a four-flute design that quickly removes dust and debris to prevent binding during use. Engineered with a no-spin shank containing three flats, it ensures a secure grip in standard 3/8-inch and 1/2-inch chucks, eliminating bit slippage during high-torque percussion drilling applications.
