Product details : DEWALT DT9425-QZ SDS-MAX MASONRY DRILL BIT 25 X 540MM
This 25 x 540mm drill bit from Dewalt has been manufactured to a very high standard courtesy of the 4 cutter X-head design for improved user comfort, reduced vibration and improved hole quality. Whether you are a professional tradesman or DIY enthusiast, the 4-flute spiral increases drilling speed and debris removal with a heavy-duty shank for maximum durability. DEWALT Extreme SDS Max Masonry Drill Bits feature innovative 4 cutter tips that maximize the hole concentricity for better fixing retention and an open-head design that channels dust into flutes for fast drilling. An elongated helix expedites mill removal, and a hardened core helps to reduce bit breakage.
