[2]: SPECIFICATION - The drill bit has a cutting diameter of 17.5mm, a shank diameter of 10mm, a flute length of 76.2mm/3 inch, an overall length of 152.4mm/6 inch, and a 135° point angle. [3]: INSTRUCTION - Drill a smaller hole first to ensure precise positioning and prevent drill deviation. Set the suitable speed according to the material's hardness and the drill bit diameter. Higher speeds can be used for softer materials, while lower speeds should be applied for harder materials. [4]: ADVANTAGE - The M2 High-Speed Steel (HSS) drill bit is suitable for drilling a variety of metals, including stainless steel, iron, aluminum, and copper. Its high hardness and wear resistance enable outstanding performance when machining harder materials. Gold Finish can further enhance the drill bit's wear and corrosion resistance, thereby extending drill bit's service life. [5]: QUANTITY INCLUDED - Set contains 1pcs x drill bit, perfect for home use, repairs (Notice: The use of coolant during the drilling process effectively reduces temperatures, extends tool life, and improves machining results.)
