Brown Carbide-tipped Masonry Drill Bit — 5/16 In (8 Mm) × 4 In (100 Mm)

BROWN Carbide-Tipped Masonry Drill Bit — 5/16 in (8 mm) × 4 in (100 mm)

Drill clean, accurate holes in concrete, brick, block, stone and mortar with the BROWN carbide-tipped masonry bit. A tungsten-carbide cutting head is brazed to a hardened steel body, giving you the hardness needed to power through tough masonry while the deep spiral flutes clear dust fast to keep the bit cutting cool. The round shank fits any standard drill chuck, so there's no special tooling required — ideal for anchoring, mounting fixtures, and running fasteners into hard surfaces.

• Size: 5/16 in (8 mm) diameter
• Overall length: 4 in (100 mm)
• Tip: Brazed tungsten-carbide, for percussion/rotary masonry drilling
• Shank: Round — fits standard keyed and keyless drill chucks (not SDS)
• Suitable for: Concrete, brick, block, natural stone, mortar
• Not for: Steel, wood, tile/glass (use the correct bit type for those materials)

Tip: Use on the drill's hammer/percussion setting where available, apply steady pressure, and back the bit out periodically to clear dust for faster, cleaner holes.
