Dormer Pramet Countersinks

A countersink removes a small amount of material at the top of a hole to:

  • Allow flat-head (countersunk) screws to sit flush with the surface
  • Deburr sharp edges after drilling
  • Improve assembly fit and surface finish
  • Reduce stress concentration around hole edges
