Review on 5Pcs Of M35 Cobalt Steel Drill Bits With Straight Shank For Efficient Cutting Of Hard Metals by David Berry

Revainrating 1 out of 5

arrived dull, became dull after a few seconds again

I bought the drill to drill out a bolt stuck in a cylinder head.Drill arrived literally dull, not sharp as everybody would expect. Then I sharpened the drill and used it.Drilled less than 1/16 of an inch before it got dull again. No quality at all.

Pros
  • HSS Titanium Coating - Classic HSS Construction With Titanium Coating For Capability And Durability. The Cutting Edge Is Hardened And Honed For Sharpness.
Cons
  • Might not be necessary for casual or infrequent use

Worked OK to drill through 6062 aluminum. Didn''t drill a lot of holes but enough to know at least it''s not a garbage drill like some.
