Carbide-Tipped Masonry Bit

The Drill America DAM24X3/8 is a carbide-tipped masonry drill bit built for professionals and DIY users who need to bore deep holes in brick, concrete and sandstone. Its 24 inch overall length provides the reach required for through-wall anchoring and renovation tasks where standard bits fall short.

Black Oxide Finish & Round Shank

A black oxide coating reduces corrosion and helps the bit run cooler during extended drilling sessions. The 3/8 inch round shank fits directly into the chuck of any portable electric drill, so no special adaptors or SDS machines are required on site.

118 Degree Conventional Point

The 118 degree conventional point is optimised for softer masonry materials and centres the bit quickly on hard surfaces. Buyers who need an SDS-plus shank or a split-point geometry for hard aggregate concrete should look elsewhere.

Questions about this item

What does the 118-degree conventional point mean for drilling speed?

The 118-degree conventional point is designed for general-purpose drilling in brick, concrete and sandstone, providing a balance of centering accuracy and material penetration.

Will the 3/8-inch round shank fit my cordless drill chuck?

The 3/8-inch round shank fits any standard three-jaw chuck that accepts 3/8-inch or larger drill bits, which covers most portable electric drills.

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

Apply steady pressure at low speed until the tip seats, then increase speed; letting the bit wander on the surface before it bites is the most common cause of tip fracture.
