- PACKING LIST: 12 packs of drill bits in #21(4.039mm/0.159") cutting diameter, 49.5mm/1.95 inch flute length, 83.5mm/3.29 inch overall length, 135° split point tip.
- FEATURE: Drill bits made of M2 high-speed steel feature high hardness and wear resistance, making them suitable for machining harder metal materials. Additionally, a Gold Finish enhances the drill bit's wear and corrosion resistance, further extending the drill bit's lifespan.
- APPLICATION: M2 high-speed steel material has good wear resistance and heat resistance, suitable for general strength drilling processing. It is particularly suited for processing medium to high-hardness materials, including stainless steel, iron, aluminum, and copper, as well as plastics and wood.
- 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 cutting fluid 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.
