Irwin 1881078 Carbide Tipped Hammer Drill Bit Set 5 Pc

Product Description

The IRWIN 1881078 is a 5-piece carbide-tipped hammer drill bit set from the Performance series, designed for drilling into masonry materials. Each bit features a carbide tip bonded to an oxide-coated steel shank, delivering the hardness needed to penetrate concrete, brick, block, and similar substrates. The set covers a range from 5/32 inch up to 1/4 inch maximum hole size, making it a practical starter or supplemental set for professionals who need reliable masonry bits on the job site. Cutting direction is forward, and the bits conform to ANSI specification designations. Measurements follow the inch system of measurement.

This set is suited for residential and light commercial applications where hammer drilling into masonry is required. Typical install scenarios include anchoring into concrete slabs or block walls, setting fasteners in brick veneer, and rough-in drilling for mechanical, electrical, or plumbing penetrations through masonry. Licensed trades including HVAC technicians, plumbers, and electricians regularly use carbide-tipped masonry bits when securing equipment hangers, conduit straps, and pipe supports to concrete or masonry surfaces. The compact 5-piece format fits easily into a tool bag or job-site kit.

Installation Notes

Installation of these bits is performed by licensed tradespeople or qualified technicians using a hammer drill set to hammer-drill mode. Secure the bit firmly in the chuck before operation and confirm the drill is powered off and unplugged or battery-removed before changing bits. Eye protection and dust control measures are recommended when drilling masonry per standard jobsite safety practices. Do not use these bits in a standard drill-only mode for extended periods, as hammer action is required to prevent overheating the carbide tip.
