SIMPLE, EASY HANDLING WITH SECURE CLAMPING 1. Place the exclusive Key Grip into the Weldon flat of the end mill shank.
2. Insert the end mill with the Key Grip in alignment with one of the three Key Grip grooves inside the milling chuck. 3. Rotate the end mill approximately 20º clockwise until the Key Grip stops securely against the stopper pin. 4. Finish clamping the tool until the clamping nut contacts the positive stop of the chuck body.
NON-PULLOUT MECHANISM The Key Grip engages in the groove of the chuck body to ensure no tool pullout.
COMPLETE FIT OF NUT AND BODY Tightening the nut achieves dual contact between the nut and body for rigidity close to that of an integral cutter.

NON-SLIP MECHANISM The Key Grip maintains contact with the stopper pin to prevent any slip under high torque.
FLOOD JET-THROUGH COOLANT The Key Grip grooves provide channels for high volume coolant to the cutter. Effective end milling of HRSAs requires a high volume of coolant to the cutting edge to dissipate heat and aid in the removal of chips.
