LHY Drill bit M35
● Product description:
1.Cobalt steel - manufactured from M35 grade 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 HSSE
2.For metal working - 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.
3.Self-centering- The 135° quick-cut points are and penetrate quickly with less pressure. No center punch is needed. Will not "walk" or "wander"
1.Application:best used for drilling in hard metal, including stainless steel
2.Can be repeatedly sharpened as needed:cobalt drill bit's hardness is uniform throughout the entire material, so that can be repeatedly sharpened without damaging the cutting edge allowing it to drill more than hss drill bits
