Fur. Titanium nitride worked better.

Not suitable for drilling in hardened steel. I'm not sure if my app was boring or wrong. Switched to a titanium nitride bit and it worked like a charm.

Pros
  • Rigid, heavy gauge construction improves bit stability in tough conditions.
Cons
  • Expensive.

Fits twist drills

I bought this to drill 18 holes in some 16 gauge steel plate. Works great, holes are clean. Drilling at the lower speed worked much better as it chewed through the steel much faster.

Pros
  • Available in jobber length, full shank
Cons
  • Out of style

Cobalt? I do not think so.

I bought this nozzle for one purpose only - to make grooves on the barrels for the gas block set screws. I filled the first keg with ease. Took maybe 3 minutes Tried to squeeze out 2 more barrels and this bit barely scratched the surface. I am very disappointed in this beat.

Pros
  • Hardened surface for punching through hard abrasive materials
Cons
  • I don't remember, but there was something
