This is a great option for drilling into harder steel as well as stainless steel grades.

Carbide (Carb) is the hardest and most brittle of the drill bit materials..

Which is better m35 or m42 Cobalt?

Cobalt High Speed Steels (HSS) M35 is also known as Cobalt Steel, HSSE or HSS-E. It will cut faster and last longer than M2. M42 is a molybdenum-series high-speed steel alloy with an additional 8% cobalt. … Tools made from cobalt-bearing high speed steels can often be identified by the letters HSS-Co.

Is cobalt or titanium drill bits better?
