About this item
  • PACKING LIST: 6 packs of drill bits in 12.5mm cutting diameter, 100mm/3.94inch flute length, 150mm/5.91inch overall length, 118° point tip.
  • FEATURE: 4341 High-Speed Steel (HSS) Twist Drills excel in medium-low speed, high-impact, and cost-sensitive applications.​ The Black and gold finish can further enhance the drill bit's wear and corrosion resistance, thereby extending its service life.
  • APPLICATION: The drill bit delivers superior all-around performance, making it the optimal choice for most metal drilling applications. Suitable for light-duty machining; applicable to low-carbon steel, aluminum alloy, brass, cast iron, medium-carbon steel, stainless steel, acrylic, plastic, wood, etc. For machining thicker metals, low RPM + flood coolant ​is required.
  • NOTE: Position the twist drill at 90° to the workpiece. For thick materials, drill in multiple passes to prevent overheating or breakage. For large holes, start with a guide hole. Use coolant to improve efficiency, extend tool life, and reduce material damage.
  • INSTRUCTION: When machining different materials, the spindle speed and feed rate vary. Generally, the harder the material, the lower the spindle speed and feed rate should be. For specific speed and feed rate recommend for common materials, please refer to the details provided on the product page.
