- COBALT STEEL - Manufactured from M35 cobalt steel, with molybdenum and cobalt added to create a hardened heat-resistant alloy, measuring Rockwell hardness up to 67, for much faster cutting and extra longer life span, with up to twelve times compared with an average HSS drill bit.
- NO CENTER PUNCH NEEDED - The 135° quick-cut split points are self-centering and can penetrate quickly with less pressure. The bits will not "walk" or "wander". Straight shank allows for firmly holding and accurate centering, fit for standard drill chucks and regular round collet chucks.
