PATIKIL 5mm Drill Bit M2 High-Speed Steel 118° for Metal 12 Pack | Jobber Straight Shank 118° Nitriding Black and Gold Finish for Stainless Steel Hard($11.49Value)

Description

PACKING LIST: 12 packs of drill bits in 5mm cutting diameter, 86mm/3.39 inches overall length, 52mm/2.05 inches flute length, 118° 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 its 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. √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 + The application of a gold finish can enhance the surface properties of the drill bit, improving its wear resistance and corrosion resistance, thereby extending its service life and operational efficiency.
The 118-degree tip angle drill is a versatile choice, suitable for soft metals, plastics, wood, and low-strength materials. It also performs well on medium-to-high hardness materials, enabling faster feed rates and higher machining efficiency.
