Masonry Carbide Drill Bits

This is an example of a Mechanical Anchor. We carry a variety of conventional drilling and anchoring systems, each of which is different in its method of taking the applied load and transferring it through an anchor to the base material. Each type is designed for a specific application. Among these types are Cast-In-Place, Drilled In, Friction, Clamping, Compression, Undercut and Bonded Anchors.
Specifically for use in masonry drilling, these drills are made of high grade heat treated alloy tool steel for maximum life. They feature a copper brazed carbide tip, Turbo™ flute design, and meet ANSI standards.

We carry Masonry Carbide Drills in three styles. See individual sizing charts within each drill style for the correct size table.
