Materials Available for Countersinking

What to expect from your countersunk parts

  • Parts may have oil/lubricant residue on the surface
  • Some light deburring may be required by the customer to remove sharp edges left by the countersinking process
  • Parts will not have a perfectly machined finish. Some scoring is expected.
  • Powder coating will add .003”-.005” (.076mm-0.13mm). We’ll adjust the hole size to account for this, but keep in mind that the fit may be tight on countersinks with powder coating
