18-Inch Carbide-Tipped Masonry Bit

This Drill America DAM series bit is built for drilling brick, concrete and sandstone using portable electric drills. Carbide tips are brazed to tough steel bodies for durability. The black oxide finish adds corrosion resistance during heavy use.

Suits anchor and toggle installations

Wide flutes clear dust quickly in softer masonry so holes stay clean for expansion shields and toggle bolts. The 118 degree conventional point starts accurately without walking. Buyers who need SDS-plus or hex shanks for rotary hammers should look elsewhere.

18 inch overall length

The 18 inch length reaches through thick walls and deep embedment points that shorter bits cannot reach. The 1/4 inch round shank fits standard drill chucks securely. California Proposition 65 warnings apply to chemicals in this product.

Questions about this item

Will the 18" overall length clear the depth I need in a brick wall?

The bit measures 18 inches overall, so it reaches deep holes in brick, concrete or sandstone; just ensure your drill chuck can grip a 1/4" round shank that long.

How do I avoid snapping the carbide tip when starting a hole in concrete?

Start at low speed with steady pressure, letting the 118-degree conventional point centre itself before increasing RPM; forcing it at full speed often cracks the brazed carbide.

When should I replace this bit if the black oxide finish wears off?

Replace once the carbide cutting edges dull or chip — the black oxide is only a surface coating, so loss of colour alone does not mean the bit is spent.
