PATIKIL 9.5mm Drill Bit 3/8", Jobber Straight Shank M2 High-Speed Steel 135° Nitriding Black for Stainless Steel Hard Metal - 5 Pack

• PACKING LIST: 5 packs of drill bits in 3/8"(9.53mm）cutting diameter, 82mm/3.23inch flute length, 125mm/4.92inch 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.

√FEATURE: The drill bit is made of M2 high-speed steel material, it has high hardness and wear resistance, suitable for processing medium-high hardness materials Nitriding Black can enhance the surface properties of the drill bit, improving its wear resistance and corrosion resistance, thereby extending the drill bits' service life and operational efficiency. The 135-degree tip angle drill provides excellent processing stability and is well-suited for harder materials. It effectively reduces the risk of cutting-edge chipping, thereby improving drilling efficiency and hole quality. √ APPLICATION: The drills are suitable for hard metals, such as steel, alloy cast iron, stainless steel, iron, copper, aluminum alloy, and cast iron. They are also effective in plastics and wood. √PACKING LIST: -Cutting Edge Diameter: 3/8"(9.53mm) -Shank Diameter: 3/8" -Flute Length: 82mm/3.23inch -Total Length: 125mm/4.92 inch -Package Content: 5pcs x Drill Bit √NOTE: When machining different materials, the spindle speed and feed rate vary.
