PATIKIL 9 Pack 1.6mm-10.2mm Drill Bit Set M2 High-Speed Steel for Metal

PATIKIL 9 Pack 1.6mm-10.2mm Drill Bit Set M2 High-Speed Steel for Metal

• PACKING LIST: This 9-piece drill bit set includes sizes from 1.6mm-10.2mm, specifically: 1.6mm, 2.1mm, 2.5mm, 3.3mm, 4.2mm, 5mm, 6.8mm, 8.5mm, 10.2mm
• FEATURE: The drill bit kit is made of M2 high-speed steel material, which has high hardness and wear resistance, suitable for processing medium-high hardness materials. It is the best all-rounder, offering the optimal balance of versatility, cost-effectiveness, and performance. With a hardness of HRC 63 and a red-hardness of 600°C, it is the preferred choice for machining carbon/alloy steels and aluminum, covering 90% of conventional scenarios from DIY to general industry.
• APPLICATION: The high-speed steel drill bit set 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, it 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 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.
