  • Does the choice of collet effect quality of cut?
Good quality collets make a difference in cut quality and tool life. They also have a limited life span and after 300 to 400 hours you can hear and see a difference. They are a consumable just like tools only with a longer life. High quality cap nuts usually last several years.

  • How and how much should you tighten the collet nut?
The best way is to use a torque wrench. Check with your collet manufacturer but a typical torque for an ER25 collet is 85 ft lbs
