Iscar introduces an upgrade to the Do-Grip parting insert. The new Jet-Cut System features a coolant hole that passes through the insert to an outlet near the cutting edge. The new DGNC inserts are designed for parting and grooving operations on stainless steel and high-temperature alloys. Often when machining these materials, the temperature near the cutting edge becomes very high, thus causing premature wear. By applying coolant to the cutting zone, this can be reduced.

The Jet-Cut inserts are designed for grooving and parting applications where there is a problem getting coolant to the cutting edge. The DGNC inserts are designed so that the coolant travels through the insert and exits a hole directly next to the cutting edge. This thereby applies coolant exactly where it needs to go while also internally cooling the insert at the same time. The application of coolant through this system has shown to increase tool life and provide a smoother surface finish. In addition, materials such as titanium, inconel and austenitic stainless steel tend to strain harden during the cutting process and thereby produce long and tangled chips. By efficiently applying cooling through the Jet-Cut system, flank and cratering rates are reduced, thus substantially increasing tool life.

 

Coolant can be supplied either directly to the DGFH-C blades used on regular blocks or through the SGTBU-C blocks, which have coolant passages or connecting ports. Inserts are available in widths of 0.118" and 0.157" in the C- and J-type chip formers.
