Bsc Preferred QJDIB-MB-008 Masonry Drill Bit 5/16 in

Product Description

The BSC PREFERRED QJDIB-MB-008 is a 5/16-inch carbide-tipped masonry drill bit engineered for impact driver and hammer drill use on concrete, brick, and masonry substrates. The carbide tip extends service life compared to standard steel bits, resisting the abrasion and heat generated during masonry penetration. A wide-flute geometry accelerates dust evacuation from the bore hole, reducing heat buildup and keeping the cutting edge cooler during extended drilling cycles. Licensed tradespeople working in residential and light commercial construction will find this bit suited to anchor setting, conduit runs, and similar penetration tasks through masonry assemblies.

This drill bit is designed for use in concrete, brick, block, and similar masonry materials. It fits standard 3-jaw chucks on rotary hammer drills and impact-rated drills, making it a practical choice for electricians routing conduit, plumbers establishing sleeve penetrations, and general contractors setting anchors in concrete foundations or CMU walls. The 6-inch working length provides sufficient depth for most anchor and sleeve applications encountered in trade service work.

Key Features

• Carbide tip for extended wear life in abrasive masonry materials
• Impact-ready design compatible with hammer drills and impact drivers
• Wide-flute profile promotes fast dust and debris removal during drilling
• Wide flute geometry aids heat dispersion to protect tip integrity
• 5/16-inch diameter x 6-inch length for anchor and penetration applications

Compatibility

Designed as an OEM-style replacement and general-use masonry drill bit compatible with standard 3-jaw chuck rotary hammer drills and impact-rated drills accepting 5/16-inch shank tooling.

Installation Notes

Installation should be performed by a qualified tradesperson following applicable safety protocols for rotary and impact drilling equipment. Disconnect or de-energize any systems in the work area before drilling through walls or slabs where embedded conduit, pipe, or rebar may be present. Use appropriate eye protection and respiratory protection when drilling masonry, as concrete dust may contain respirable silica. Allow the bit to clear dust regularly during deep drilling to prevent overheating and premature carbide tip wear.
