Bsc Preferred QJDIB-MB-013 Masonry Drill Bit 5/16x12

Product Description

The BSC PREFERRED QJDIB-MB-013 is a carbide-tipped masonry drill bit designed for drilling through concrete, brick, and similar hard masonry materials. The bit measures 5/16 inch in diameter with a 12-inch working length, making it well-suited for deep anchor holes and through-penetration work. The carbide tip delivers extended wear life compared to standard steel bits. A wide flute design accelerates dust evacuation and reduces heat buildup during prolonged drilling, helping maintain consistent cutting performance. The impact-ready construction makes it compatible with rotary hammer drills and impact-rated drill drivers used by electricians, plumbers, and general contractors on commercial and residential jobsites.

This drill bit is intended for use in masonry applications including concrete slab penetrations, brick wall anchoring, block foundation work, and conduit or pipe sleeve installations. The 12-inch length provides reach through standard wall thicknesses and structural members where shorter bits fall short. It is a practical single-unit addition to a tool bag for service calls requiring occasional masonry drilling without carrying a full set.

Installation Notes

Masonry drilling is typically performed by licensed electricians, plumbers, or contractors during rough-in or anchor-setting phases. Always wear appropriate eye protection and a dust mask when drilling masonry, as fine silica dust is a respiratory hazard. Confirm the drill setting matches the bit type — use hammer or rotary-hammer mode for concrete, not drill-only mode, to avoid premature tip wear. Ensure the work area is clear of embedded conduit, rebar, or utilities before beginning.
