JCT series

Excellent chip control and long tool life with high pressure coolant. Large holder lineup for turning, external grooving, cut-off and threading.

Special coolant hole design

Unique coolant system for various machining applications

Turning: Double clamp-JCT (left), external grooving: KGD-JCT (middle), Threading: KTN-JCT (right)

Double clamp-JCT

Discharges coolant in three directions. Improved chip control and longer tool life for a wide variety of workpieces including steel, hardened material and difficult-to-cut material.

1. Superior chip control performance
   
   
   

   1. Double-clamp: Firm insert clamp and easy to use in single operations. High-density coolant supply close to the cutting edge.

   2. Unique nozzle shape: Provides coolant to a wide area of the cutting point.
   
   

2. Longer tool life and high speed machining
   Coolant is also directed from two directions towards the flank face of the insert to ensure effective cooling action. Longer tool life and high-speed machining with improved wear resistance.

KGD-JCT

Coolant is directed from the rake surface and the flank face of the insert. Improved chip control and longer tool life for external grooving and cutting-off.

Discharges coolant in two directions:

• Discharges coolant in two directions toward both the rake surface and the flank face of the insert.
• Excellent chip control and long tool life.

1. Superior chip control performance:
   Coolant towards the rake face. Coolant hole position and angle improve chip control
2. Cooling the cutting edge leads to longer tool life:
   Coolant towards the rake surface and the flank face of the insert. Directing coolant towards the cutting edge lengthens tool life.
3. Large chipbreaker lineup for various machining applications

KTN-JCT

New threading toolholder. Two coolant holes reduces defects and lengthens tool life.

1. Improved tool life lowers machining costs:
   Coolant flows from the top of the clamp. Efficient cooling of the cutting edge prevents wear.
   
   
2. Prevents chip recutting:
   Coolant from the flank face of the insert smoothly evacuates chips away from the cutting edge. Reduced chip clogging. Coolant from the flank face does not flow directly to the cutting edge.

TQ chipbreaker

Improved chip control with molded chipbreaker. Combination with KTN-JCT for greater productivity.
