Description
The drill bit is made of M2 high-speed steel material, which has high hardness and wear resistance, making it suitable for processing medium-high hardness materials
Nitriding Black can enhance the surface properties of the drill bit, improving its wear resistance and corrosion resistance, thereby extending the drill bit's service life and operational efficiency.
The 135-degree split point tip drill provides excellent processing stability and is well-suited for harder materials. It effectively reduces the risk of cutting-edge chipping, improving drilling efficiency and hole quality.
√APPLICATION:
The drills are suitable for hard metals, such as steel, alloy cast iron, stainless steel, iron, copper, aluminum alloy, and cast iron. They are also effective in plastics and wood.
