Cobalt Drill Bits

The Cobalt drill bit series at OEM Tools Direct complies with strict ANSI specifications.  Our drills are precision ground from M-35 Cobalt High Speed Steel with an HRC 63-66. Our bit web design has thicker core than a standard drill bit, which provides maximum strength and reduces side-load breakage. A unique parabolic flute form clears chips and debris fast to keep the bit performing at low temperatures To prevent walking on the work surface and provide a quick start on contact, we make the 135 Split Point Tip a standard feature on all of our industrial graded drill bits 3/16" diameter and larger.   The SURE-Grip Tri-Cut Shank (3/16" and Larger)helps reduce the possibility of the drill spinning out during use. Our Cobalt drills are designed for Stainless Steel and Tough Metal drilling where high temperatures occur.
