【TiAIN Coating】TiAlN coating has excellent characteristics. As a new coating material, which can minimize the wear of the drill bit during each drilling process. It is extremely hard, can withstand high oxidation temperatures, and has excellent thermal hardness. In addition, it has strong adhesion, low coefficient of friction, and low thermal conductivity, making it ideal for demanding applications.
【M35 Cobalt Material】M35 cobalt high-speed steel can be obtained by proper heat treatment with high hardness, high red hardness, and high wear resistance. It boasts higher toughness and bending strength than ordinary high-speed steel.
【13 Step Size】 The specifications of step drills range from 1/8"-1/2": 1/8", 5/32", 3/16", 7/32", 1/4", 9/32", 5/16", 11/32", 3/8", 13/32", 7/16", 15/32", 1/2". Each type of step drill contains a variety of specifications, which can be wider to meet your needs, and you don't need to replace drill bits frequently, saving you valuable time.
【135° Cutting Angle】When drilling hard materials, the angle of the drill tip is important. That's why we designed our drills with a 135° cutting angle. This angle reduces self-wear and provides a larger stress area, resulting in cleaner, more efficient drilling.
