Not for nonferrous materials.
Bright Not real finish, but polished for increased chip flow.
For use in plastics, woods and aluminum..
Are titanium drill bits any good?
Titanium drill bits are high-speed steel drill bits (HSS) that have a titanium oxide coating. … They last much longer than regular HSS drill bits, and they are good for cutting through any metal, including metal sheeting. Titanium drill bits are harder than cobalt, but because they are coated, they can’t be sharpened.
Are cobalt drill bits stronger than titanium?
The type of titanium coating makes a difference though. For example, titanium carbonitride coating can typically handle tougher materials than titanium nitride coating. Cobalt drill bits are best for the toughest materials, like cast iron and other metals that are particularly abrasive.
Can Cobalt Drill Bits be sharpened?
