A steam-annealed coating provides improved lubricity and helps resist built-up edge, while the patented Silver ring marks the diameter clearly. The shank is cylindrical for compatibility with standard drill chucks, and the design supports regrinding when needed. These bits are intended for general-purpose drilling in steel and cast iron and are suitable for use with drill presses and handheld drills. The product is supplied in multiple pieces per package.
