Hymnorq 1/8 Inch Fractional Jobber Twist Drill Bit Set of 10pcs, Heat Resistant M35 Cobalt Steel, Fully Ground and Straight Shank, Suitable for Repeated Drilling in Iron and Stainless Steel

Brand: Hymnorq

HSS-CO MATERIAL - Manufactured from M35 grade cobalt steel, 5% cobalt added to creates a hardened alloy, for much faster cutting and extra longer life span, with up to twelve times when compared with an average HSS drill bit.
135°SPLIT POINT - the 135°quick-cut split point are self-centering and able to penetrate metals quickly with less pressure, prevent bits from "walking and wanding". Easy cutting without need of center punch.
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. Not for hardened steel / high carbon steel. Try to adjust the RPM when it fails to penetrate.
10PC SET - The set includes 10pcs of 1/8" diameter M35 grade cobalt steel twist drill bits, packed in a plastic case for easy storage and carrying. Manufactured to German DIN338 standard.
