Internal coolant system
Strong and reliable clamping mechanism prolongs tool life.
Coolant jet directed to the cutting edge.
External diameter holder lineup: 20mm square and 25mm square (C, D, and W insert can be attached.)
Internal diameter holder: Minimum cutting diameter Φ40 (The standard product is a type with a CN12 insert attached.
Coolant efficiency difference by insert temperature
Coolant efficiency drops by coolant evaporation when the insert temperatur is high.
It is possible to increase the efficiency of coolant supply by keeping the cutting edge cool properly
Minimum cutting diameter is Φ40 for internal diameter
Only Iscar has a standard lineup of hollow clamp that serves also as coolant nozzle with a minimum cutting diameter of Φ40.(According to our research in 2019)

Machining test with middle pressure machine
Coolant supply from copper pipe vs. Coolant supply from JETCUT
Machine：DMG MORI NL2000/700MC
Depth of cut：ap=1.0mm
Coolant：Emulsion with 8%
Coolant supply from copper pipe
Both looks to be able to properly jet to the cutting edge.
How different the coolant supply efficiency by different coolant system?
Coolant supply from JETCUT
With the copper pipe supply, boundary wear and welding became remarkable from 126-pass and occurred chipping of the cutting edge.
On the other hand, with JETCUT supply, the progress of wear and welding is suppressed even after 126-pass.
In addition, JETCUT get slightly welded at the end of 150-pass, but it is about the same condition as 66-pass with the copper pipe supply. It can be judged that continuous machinign is possible.
As a test result, JETCUT can further extend tool life than copper pipe supply even the coolant is supplied accurately from copper pipe.
Please refer Iscar web site for more detail.
C type internal diameter holder：
Machining on stainless teel and titanium
Good choice for machining where welding is occurred on the cutting edge.
Finishing machining of steel
Good choice for finishing machining of steel since the cuttig edge is quickly welded by the steel workpiece.
High efficiency internal coolant
By supplying from the wedge clamp, you will be able to get better clamp rigidity and high efficient coolant supply.
Free from readjustment of the nozzle
Readjustment of nozzle is not necessary at tool replacement and insert changing.
