Irwin 4935076 Hammer Drill Bit Set 5 Pc 5/32 to 1/2 in Hss

Product Description

The IRWIN 4935076 is a 5-piece hammer drill bit set designed for masonry drilling applications. Manufactured from high-speed steel with a bright, uncoated finish, these bits are built to handle concrete, brick, block, and similar hard materials. The set covers five sizes ranging from 5/32 inch to 1/2 inch, giving technicians a ready range of diameters for anchors, fasteners, and rough-in work. Each bit features a 6-inch overall length with a 3-1/2-inch flute length, providing adequate depth capacity for standard masonry penetrations. Licensed contractors and trade professionals working in residential and light commercial construction will find this set suited for everyday anchor and penetration tasks.

This set is intended for use with rotary hammer drills in masonry and concrete applications. The five discrete hole sizes allow a single kit to cover common anchor sizes encountered on a typical job site. The 6-inch overall length accommodates standard wall and block thicknesses. Plumbers, electricians, and HVAC technicians running conduit, pipe, or refrigerant line penetrations through masonry walls will find the size range practical for most rough-in scenarios. The uncoated finish is standard for high-speed steel masonry bits used in moderate-duty rotary hammer work.

Installation Notes

Installation should be performed by qualified trade professionals familiar with rotary hammer operation and masonry drilling procedures. Confirm the hammer drill is in hammer-drill mode before use, and wear appropriate eye and respiratory protection when drilling masonry. Ensure the drill bit shank matches the chuck type of the tool before operation. Do not use these bits in standard drill-only mode on masonry, as this will damage the bits and produce poor results.
