Quality Control

Nothing Leaves Here
Unmeasured.

A resharpened tool is only worth what it measures. Every job that comes through our door runs the same four steps — no exceptions, whether it's one endmill or a batch of five hundred.

  1. 01
    Ultrasonic Cleaning Coolant, resin, and buildup come off before anything is measured or ground.
  2. 02
    Full Inspection Each tool is checked against spec. Chips, cracks, and worn geometry get flagged before we grind — and we tell you when a tool isn't worth saving.
  3. 03
    CNC Grinding Ground back to OEM geometry — or to your print — on the same equipment used to manufacture new tooling.
  4. 04
    Final QC Measured again after grinding. Straight knives are hand-honed. Nothing ships until it checks out.
