Product Description

 

Product Description

• COBALT STEEL - Manufactured from M35 cobalt steel, with molybdenum and cobalt added to creates a hardened alloy, measuring Rockwell hardness up to 67, extremely heat resistant; 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". Straight shank allows for firmly holding and accurate centering, fit for standard drill chucks and regular round collet chucks. Must be used and operated at proper RPMs for maximum efficiency
• 8PC METRIC BITS - The set includes 8pcs of M35 cobalt steel twist drill bits: 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm. Well organized in a plastic indexed storage case for easy transport to your worksite.
• FOR METALWORKING - 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.
