Specifications

Pro-Tip: When drilling through thick or stainless metals, use a lower RPM and apply a small amount of cutting fluid or lubricant. This significantly reduces heat friction, which is the primary cause of bit dulling, and ensures your Diablo step bits stay sharp for thousands of clean, professional holes.
