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

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

Superior chip control performance

Coolant towards the rake face

Coolant hole position and angle improve chip control

Wear resistance comparison (In-house evaluation)

Cutting conditions: Vc = 180 m/min, f = 0.15 mm/rev, d = 9 mm, wetEdge width 4 mm, workpiece: 15CrMo4, grooving

Cooling the cutting edge leads to longer tool life

Large chipbreaker lineup for various machining applications

Coolant towards the rake surface and the flank face of the insert. Directing coolant towards the cutting edge lengthens tool life.

KGD-JCT minimizes wear and provides longer tool life without insert fracturing

Cutting conditions: Vc = 150 m/min 16ER150ISO type (PR1215), workpiece: 34CrMo4, radial infeed

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.
