Quality


PIONEER products meet and/or exceed all industry and catalog specifications.  We do not believe in using averages, our goal is to hold 1/2 of the specified tolerance on all products.

The How:
PIONEER uses Stotz Air/Electronic Gaging for production and finish inspection of all tapers.  Stotz has been chosen major aircraft companies as the best and most consistent gaging for tool holder shanks.
  • All tools are 100% inspected.
  • All tool holders (excluding DC, JT, MA, SB & Tap Holders) are Dynamically Balanced higher than Industry Standard.  PIONEER uses Haimer balancing machines at all locations for consistent balance.
