About this item
  • Size - Working diameter 3.9mm / 0.15inch, working length 43mm / 1.69inch, total length 72mm / 2.83inch, including 15pcs drill bit.
  • Cobalt Material: The drill bit for metal is made of high-speed steel with M35 cobalt, provides high hardness(HRC64-HRC66), good toughness, and wear resistance.
  • Fast Drilling - The fully ground spiral groove design of the metal drill bits can quickly remove debris, reduce friction and heat, and drill faster. The 135 ° straight shank split point reduces walking on the working face, making drilling accurate and easy.
  • Application - Cobalt twist drill is suitable for hardened materials and hard metals, such as stainless steel, mould steel, cast iron, aluminum alloy, copper and hard plastics, and also suitable for soft materials.
  • Note - Please note that these small drill bits are not suitable for glass, tile, wall, stone or ceramic materials, pay attention to speed, pressure, and heat control when drilling.
