[Features]:
1. High-speed steel, cobalt after heat treatment, high hardness, high wear resistance, high toughness, flexural strength, sharp edge, for machining stainless steel, better than ordinary ladder drills.
2. The unique step structure, a variety of different diameters can be drilled, no center punch, more secure than the twist, more durable.
3. "X" shaped openings, drilling is not easy to slip. High drilling performance, Low cutting resistance.
4. Quality chip resistance and heat dissipation. Plated cobalt coating, more wear and oxidation resistance, not rust.
5. Higher precision, more sharp, burr-free drilling. Also can deburring, chamfering, red oval hole, etc.
6. Suitable for pistol drills and bench for punching harder these artifacts, such as stainless steel, carbon steel, aluminum, iron, etc. limiting the thickness of 4mm or less!
