What are the Best Drill Bits for Stainless Steel?

In daily life, we sometimes need to drill stainless steel, so what are the best drill bits for stainless steel

Can I Drill Thin Stainless Steel with a Wood Drill Bit?

The answer is no, maybe you’ll ruin the wood drill bit and the stainless steel that you drill,Some wood drill bits can’t even touch the stainless steel

It is better to buy the correct drill bits and use that and different types of drill bits are used to drill holes in different kinds of materials

For drilling in stainless steel, HSS cobalt drill bits are the best option

Cobalt Drill Bit is Successful in Cutting Through the Hard Metals

1. Cobalt drill bits are not made of pure cobalt
2. It includes 5 to 8 percent cobalt
3. The 5-percent alloy is M35 grade, and the 8-percent alloy is M42 grade
4. The cobalt increases the strength of the steel
5. Cobalt make it more heat-resistant
6. It can easily cut through hard metals without damaging the surface

HSS Drill Bit Advantage

1. High speed steel is a tool steel with high hardness, high wear resistance and high heat resistance
2. Good surface treatment process ability
3. High surface hardness after hardening
4. After sharpening, the cutting edge is sharp and the quality is stable

High-Speed Steel can be Divided into the Following Types

1. HSS 4241（can drill casting iron, carbon steel）
2. HSS 4341（can drill aluminum ,bronze, casting iron）
3. HSS 9341（can drill iron, aluminum, angle iron）
4. HSS M2/6542（stainless steel, aluminum ,bronze, casting iron）
5. Cobalt（can drill stainless steel, aluminum ,bronze, casting iron
