Coolant Cap System

Coolant cap systems can affect TIR. Follow the procedure below to eliminate TIR with SX coolant caps:

SX coolant cap
  1. Insert Collet into collet nut
  2. Insert Cap into the nut, leave loose to allow the cap to float to the cutting tool
  3. Insert Cutting Tool
  4. Tighten Collet Nut onto the chuck to recommended tightening torque
  5. Snug Coolant Cap
