IRWIN 322017B25 Drill Bit 1/4" 4" 6" Speedhammer Plus Standard Tip, 25-pack

When speed and reliability matter on site, the IRWIN 1/4" Speedhammer Plus SDS-plus masonry drill bits deliver consistent performance for contractors and installers. This 25-pack of drill bits is engineered for heavy use—featuring a copper-brazed ANSI-standard tip and a through-hardened chrome vanadium shaft (50–53 HRC)—so you spend less time changing bits and more time completing jobs. Compatibility with SDS-plus and Hilti TE-C rotary hammers makes them a simple choice for crews using popular rotary hammers. The patented tip and flute geometry improves dust removal by up to 25%, producing cleaner holes and faster drilling when mounting security cameras, routing conduit for surveillance systems, or installing monitoring equipment. Hot isostatic pressing and a shot-peened, double-tempered finish resist breakage under demanding conditions, giving you longer service life on concrete and masonry. Keep a reliable supply in your job box to reduce downtime and maintain installation speed. Add these IRWIN masonry drill bits to your toolkit for faster, longer-lasting drilling on every security, surveillance, or general construction project.
