Carbide-Tipped Masonry Bit

The Drill America DAM30X1/2 is a carbide-tipped masonry drill bit built for portable electric drills. It features a 3/8" round shank, spiral flutes and a 118 degree conventional point. The overall length is 30". The black oxide finish adds corrosion resistance for drilling in brick, concrete and sandstone.

Wide Flutes for Dust Removal

Wide flutes are engineered to provide fast dust removal in softer materials. Carbide tips are brazed to tough steel bodies and are larger than the nominal drill size. This clearance helps installation of anchor screws, expansion shields and toggle bolts. The design supports cleaner holes in masonry substrates.

For Masonry Anchoring Tasks

This bit suits users drilling deep holes for anchors in brick, concrete or sandstone with a portable electric drill. It is not for buyers who need a bit for metal, wood or tile work. The 3/8" round shank limits compatibility to chucks accepting that size. The Proposition 65 warning notes chemicals linked to cancer and reproductive harm.

Questions about this item

How often will the carbide tip need replacing when drilling into concrete?

The carbide tip is brazed to the steel body and cannot be replaced separately; once the tip dulls or chips the entire 30 inch bit must be discarded.

What stops the bit from drilling deeper in a single pass?

The 30 inch overall length sets the maximum hole depth achievable without withdrawing the bit to clear dust.

Does the black oxide finish reduce heat build-up during all-day use?

The black oxide coating mainly resists corrosion; heat is managed by the wide spiral flutes that eject dust quickly from brick, concrete and sandstone.
