DETAILS
- Cobalt-coated for use on metals, such as stainless steel or carbon steel
- 10 steps: 1/4" to 1-3/8" (1/4", 3/8", 1/2", 5/8", 3/4", 7/8", 1", 1-1/8", 1- 1/4", 1-3/8")
- Manufacturer's Notes: This durable step drill is made of HSS M35 cobalt, and the surface is plated with cobalt. The hardness, wear resistance and toughness is stronger, not easy to become dull or broken. It is an ideal choice for cutting carbon steel and stainless steel. Perfect for expanding the hole in stainless steel, such as the kitchen sink hole. The addition of cobalt increases heat resistance and is widely used in metal manufacturing.
