PATIKIL #48 Drill Bit, Jobber Straight Shank M2 High-Speed Steel 135°Split Point Tip Nitriding Black for Stainless Steel Hard Metal - 12 Pack

PATIKIL #48 Drill Bit, Jobber Straight Shank M2 High-Speed Steel 135°Split Point Tip Nitriding Black for Stainless Steel Hard Metal - 12 Pack

PACKING LIST: 12 packs of drill bits in #48 (0.076 inch / 1.93mm) cutting diameter, 25mm/0.98 inch flute length, 50mm/1.97 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. √FEATURE:
The drill bit is made of M2 high-speed steel material, which has high hardness and wear resistance, making it 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 bit's service life and operational efficiency.
The 135-degree split point tip drill provides excellent processing stability and is well-suited for harder materials. It effectively reduces the risk of cutting-edge chipping, 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.
