What are HSS drill Bits?

‘High speed steel’ bits are very hard and have a high resistance to heat which allows them to drill into various materials. They can be drilled into metal, hardwood and most other materials. They cut at a higher speed than carbon steel bits which have largely been replaced by them now.

What Are Cobalt drill bits?

Cobalt drill bits are variations of high speed steel drill bits. They are a steel alloy with more cobalt.  This allows it to function at higher temperatures. They can be used to drill stainless steel and other hard materials as well as softer materials. The downside is that they are more brittle than normal HSS drill bits. HSS Cobalt drill bits are more expensive than normal HSS drill bits. However, they are well worth the extra cost for frequent drilling and tougher applications.
