QUESTIONS & ANSWERS
Ask a Question-
What are the difference between turbo and cobalt bits?
Physically the differences are the material they are manufactured from and the geometries of the flutes and cutting tips.
In terms of application the Cobalt bits are most suitable for use in stationary machines (such as a drill press) where the Turbo bits are designed specifically for use in handheld drilling machines.
