Drill America 18-Inch Masonry Bit

The Drill America DAM18X7/16 is a carbide-tipped masonry drill bit designed for use in portable electric drills. It targets tradespeople and DIY users who need to drill deep holes in brick, concrete and sandstone. The black oxide finish helps resist corrosion during storage and on the job site. Its 18-inch overall length provides extended reach for through-hole applications.

7/16-Inch Diameter With Clearance Oversize

The single specification that decides fit is the 7/16-inch nominal diameter combined with carbide tips brazed larger than the nominal size. This oversize geometry creates clearance for anchor screws, expansion shields and toggle bolts. The 3/8-inch round shank fits standard drill chucks without requiring a specialised holder. Match the anchor hardware to this diameter before purchasing.

Sustained Drilling In Soft Masonry

Wide spiral flutes are engineered to remove dust quickly in softer materials such as brick and sandstone. Fast dust evacuation reduces binding and heat build-up during long, continuous drilling sessions. The 118-degree conventional point maintains centring without walking on hard surfaces. Carbide tips brazed to tough steel bodies resist wear when drilling repeated holes to full 18-inch depth.

Questions about this item

What does the 18 inch length mean for reach in a real job?

The 18 inch overall length lets you drill deep holes through thick brick or concrete walls without needing an extension.

How does the 3/8 inch round shank limit what drills can run it?

The 3/8 inch round shank fits any portable electric drill with a 3/8 inch or larger chuck, so it caps at that chuck size.

What clearance does the 7/16 inch bit need to mount an anchor?

The carbide tip is ground larger than the nominal 7/16 inch size to give clearance for anchor screws, expansion shields and toggle bolts.
