Carbide-tipped masonry drill bit designed for boring clean holes in brick, block, and concrete. The 1/4" universal hex shank seats into Rapid Load quick-change chucks for tool-free swaps, and also fits any standard hex bit holder or three-jaw drill chuck so it works across cordless drills, corded drills, and hammer drills in rotary-only mode.

• Tip diameter: 1/4"
• Carbide cutting tip for masonry materials
• 1/4" hex shank, Rapid Load / quick-change compatible
• For brick, block, and concrete drilling
• Rotary-only mode (not for SDS hammer-impact)
• Hex flats resist slip and walking in the chuck

Application: 1/4" is the pilot size for 5/16" tapcons and 5/16" sleeve anchors, and for setting plastic and lead anchors up to a 1/4" screw. Common for mounting handrails, light fixtures, and heavier shelving to brick or block.

Tip: Run a cordless drill at moderate speed with steady pressure, and pull the bit out every few seconds to clear dust from the flutes - heat and dust loading are the leading causes of carbide tip failure. For deeper or harder concrete holes, switch a hammer drill to rotary-with-hammer mode; this bit handles rotary-with-hammer percussion but is not designed for SDS-style impact.
