M35 Cobalt Steel – Manufactured from M35 cobalt steel, with molybdenum and cobalt added to creates a hardened alloy, measuring Rockwell hardness up to 67, for much faster cutting and extra longer life span, with up to twelve times when compared with an average HSS drill bit.
No Center Punch Needed – the 135° quick-cut points are self-centering and penetrate quickly with less pressure. Will not “walk” or “wander”
For Stainless Steel – Particularly successful in cutting through hard metals such as stainless steel and cast iron, although they can be used for softer materials, too. Not for hardened steel / high carbon steel. Try to adjust the RPM when it fails to penetrate.
