[1]: APPLY TO - The drill bit is suitable for daily equipment maintenance and repair, low-intensity applications, and medium to low-hardness metals, including common stainless steel, steel, aluminum alloy, and copper. It is also effective for drilling wood and plastic materials, making it an excellent choice for various DIY projects around the home. [2]: SPECIFICATION - The drill bit has a cutting diameter of 8mm, a shank diameter of 8mm, a flute length of 77mm/3.03 inches, an overall length of 115mm/4.53 inches, and a 118-degree standard point tip. [3]: INSTRUCTION - 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. Please refer to the details provided on the product page. [4]: ADVANTAGE - The 4341 high-speed steel material has high hardness, good wear resistance, and toughness, enabling it to withstand significant impact without easily breaking. Black and gold finish can further enhance the drill bit's wear and corrosion resistance, thereby extending its service life. [5]: QUANTITY INCLUDED - Set contains 5pcs x 8mm twist drill bits, perfect for home use, repairs, and small manufacturing projects. (Notice: it is recommended to first drill a small guide hole before drill a larger hole) APPLY TO - This drill bit is well-suited for low-intensity applications and DIY projects. It can handle a variety of materials, including common stainless steel, steel, aluminum alloy, copper, plastics, and wood, making it perfect for daily equipment maintenance and repairs.

SPECIFICATION:
-Cutting Edge Diameter: 8mm
-Cutting Edge Length: 77mm/3.03 inch

QUANTITY INCLUDED - Set contains 5pcs x 8mm drill bits

ADVANTAGE - The 4341 high-speed steel material has high hardness, good wear resistance, and toughness, enabling it to withstand significant impact without easily breaking. Black and Gold Finish can further enhance the drill bit's wear and corrosion resistance, thereby extending its service life. With a 118-degree standard point angle, these drill bits facilitate faster feed rates and higher processing efficiency.

EXPLAIN - These drill bits are suitable for general metal machining and light-duty applications at low speeds, the use of coolant during the drilling process effectively reduces temperatures, extends tool life, and improves machining results.
