Why a Reamer Cuts Oversize

An oversize reamed hole can come from excessive allowance, runout, poor alignment, speed or a worn reamer.

Reamers: selection checklist

  • Leave the correct drilling allowance.
  • Keep the reamer aligned and supported.
  • Use proper feed and lubricant.

How to choose the right option

  1. Stop and inspect the tool, workpiece and machine interface.
  2. Correct the size, geometry, setup or cutting condition involved.
  3. Run a controlled test and inspect the result before returning to production.
