PATIKIL 13/32" Drill Bit M2 High-Speed Steel 135° Nitriding Black 2Pcs

PATIKIL 13/32" Drill Bit M2 High-Speed Steel 135° Nitriding Black 2Pcs

• PACKING LIST: 2 packs of drill bits in 13/32"(10.319mm) cutting diameter, 98.43mm/3.88inch flute length, 133.35mm/5.25 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 medium and high hardness metal. Additionally, the nitriding black surface enhances the drill bit's wear and corrosion resistance, further extending the drill bit's lifespan.
• APPLICATION: The M2 high-speed steel drill bit delivers superior all-around performance, making it the optimal choice for most metal drilling applications, including low/medium-carbon steel, alloy steel, stainless steel, cast iron, and aluminum alloys. When drilling harder materials such as high-carbon steel, stainless steel, and alloy steels, is recommended to use a coolant to reduce wear
• 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 drill bits' 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.
