Drill America 30" Masonry Bit

This 30 inch carbide-tipped masonry bit from Drill America targets professionals drilling deep holes in brick, concrete and sandstone. The round shank fits standard portable electric drills. It is not suited for metal, wood or tile work requiring specialised cutting geometries.

3/8" Clearance for Anchor Hardware

The bit diameter runs slightly larger than the nominal 3/8 inch size to give clearance for anchor screws, expansion shields and toggle bolts. Wide flutes evacuate dust quickly in softer masonry. Length provides reach but leverage increases with depth so control becomes harder in very hard aggregate.

Black Oxide Finish Resists Corrosion

Black oxide coating helps protect the steel body from rust during storage and on damp job sites. The 118 degree conventional point starts cleanly in masonry without a pilot hole. Carbide tips are brazed to tough steel bodies for durability. California Proposition 65 warnings apply to this product.

Questions about this item

Will the 30" overall length reach through deep masonry when paired with my older 1/2" chuck drill?

The bit has a 3/8" round shank, so it fits any 3/8" or larger chuck; the 30" length adds reach for deep holes in brick, concrete or sandstone.

How can I confirm the 118-degree conventional point is cutting cleanly after I start drilling?

Watch for steady, even dust ejection through the wide spiral flutes and a round, properly sized hole that matches the carbide tip diameter.

Does the single-bit pack include any anchors or shields, or must I buy them separately?

Only the carbide-tipped masonry drill bit with black oxide finish is included; anchor screws, expansion shields and toggle bolts are sold separately.
