PATIKIL 7.5mm Drill Bit 19/64", Jobber Straight Shank 4341 High-Speed Steel 135° TiN Coated for Medium-hard Metal Steel Acrylic - 10 Pack

• PACKING LIST: 10 packs of drill bits in 19/64" (7.541mm) cutting diameter, 76mm/2.99inch flute length, 110mm/4.33inch overall length, 135° point tip.
• FEATURE: 4341 High-Speed Steel (HSS) Twist Drills excel in medium-low speed, high-impact, and cost-sensitive applications.​ The The titanium nitride (TiN) coated can prevent further oxidation or corrosion of the drill bits and extend the service life.
• APPLICATION: The drill bit delivers superior all-around performance, making it the optimal choice for most metal drilling applications. Suitable for light-duty machining; applicable to low-carbon steel, aluminum alloy, brass, cast iron, medium-carbon steel, stainless steel, acrylic, plastic, wood, etc. For machining thicker metals, low RPM + flood coolant ​is required.
• 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 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 4341 high-speed steel material, it has high hardness and wear resistance, suitable for processing medium hardness materials The titanium nitride (TiN) coated can prevent further oxidation or corrosion of the drill bits and extend the service life. The 135° split point tip 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 4341 hss drills are suitable for light-duty machining; applicable to low-carbon steel, aluminum alloy, brass, cast iron, medium-carbon steel, stainless steel, acrylic, plastic, wood, etc. For machining thicker metals, low RPM + flood coolantare required. √PACKING LIST: -Cutting Edge Diameter: 19/64" (7.541mm) -Shank Diameter: 19/64" -Flute Length: 76mm/2.99 inch -Total Length: 110mm/4.33 inch -Package Content: 10pcs x Drill Bit √NOTE: When machining different materials, the spindle speed and feed rate vary.
