![]() Black oxide coatings are more durable than high-speed steel, as they resist rust and corrosion. Some drill bits have coatings to improve their performance. Saw drill bits intended to cut through masonry have a diamond coating instead of a blade, which grinds cleanly through tile, brick, and other masonry. The blade attaches to a mandrel or arbor that, in turn, connects to the drill. A saw drill bit has a cup shape with a saw blade that runs around the rim of the bit.
