Questions & Answers

Will these last longer drilling aluminum? Or would they be overkill for aluminum?

Just wondering if these are worth the extra cost vs black oxide?
Asked by: Cbus1992
Should be fine. As a matter of fact I believe that most if these drill bits are mostly intended to be use in wood and aluminum as a matter of practicality; anything else is a matter of you get what you pay for.

Question is about Thunderbolt Cobalt drill bit specifications

Item description does not specify either hardness (M42, M36, etc.) or Cobalt percentage (5%, 8%, etc.). Are these bit solid Cobalt Alloy Steel or simply coated High Speed Steel bits? Item description also says they are Titanium coated, probably a typo.
Asked by: ztywa6
It appears that these bits are titanium coated but they are not even hardened to minimum hardness standards. As for the high speed part they overheat using cutting oil.
