Irwin 322048 Sds-plus Carbide-tipped Rotary Hammer Drill Bit

Product Description

The IRWIN 322048 is a carbide-tipped rotary hammer drill bit designed for drilling into masonry and concrete. It features an SDS-Plus shank for use with SDS-Plus rotary hammers, providing positive engagement and efficient impact energy transfer. The bit is constructed from carbide-tipped high speed steel for durability in hard aggregate materials. With a 3/4-inch diameter, 10-inch flute length, and 12-inch overall length, it handles deeper anchor and penetration holes in block, brick, and poured concrete without an extension. Licensed tradespeople and contractors reach for this bit on commercial and residential concrete work alike.

The IRWIN 322048 is suited for masonry drilling applications including anchor bolt holes, conduit penetrations, and structural openings in block, brick, and concrete. It fits any SDS-Plus rotary hammer, making it a common choice on electrical, plumbing, HVAC, and general construction job sites where core and through-penetrations are required. The single-flute design moves debris out of the hole efficiently during hammering cycles, reducing bit binding in deep cuts.

Installation Notes

Installation is performed by electricians, plumbers, HVAC technicians, and general contractors using SDS-Plus rotary hammers. Always wear eye protection and a dust mask when drilling masonry. Insert the bit fully into the SDS-Plus chuck until the retention collar locks before operation. Consult applicable building codes, including the NEC and IPC, when drilling penetrations through fire-rated assemblies or structural members.
