  • 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.
  • SELF CENTERING - The 135quick-cut pilot 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.
  • 2PC 29/64 INCH FRACTIONAL BITS - The set includes 2pcs of M35 cobalt steel twist drill bits. Total length - 5.63 Inch; working length - 4.17 Inch. Manufactured to German DIN338 standard. Packed in a plastic bag and a flat paper box.
  • FOR METALWORKING - Particularly successful in cutting through hard metals(hardness less than HRC38) such as stainless steel and cast iron, although they can be used for softer materials like copper and aluminium, too.
