Working Mechanism

  • Select a drill bit to be measured and insert it into the holes on the gauge.
  • Slides the bit into the holes until you find the hole that offers the closest fit.
  • Once the correct hole is found, clearly see the diameter measurement indicated by the hole. This measurement corresponds to the diameter of the drill bit being assessed.
  • To ensure accuracy, check that the flutes or cutting edges of the drill bit align perfectly with the edges of the hole, verifying the correct size and alignment.
  • Note down the size indicated by the hole. This measurement provides a precise value for the diameter of the drill bit.

  • It features steel construction with matte finish for longevity and durability.
