Internally cooled inserts for grooving and parting off
The S100 single cutting edge insert and the S224 double cutting edge insert from HORN are available with internal coolant supply through the insert.
The targeted coolant jet acts directly on the point of cutting, thus ensuring optimum cutting conditions. The funnel-shaped nozzle creates a coolant jet which actively supports chip formation and thus reduces the chance of chip jamming. Furthermore, this type of internal cooling significantly reduces the formation of built-up edges and fractures on the cutting edge. Unlike conventional cooling methods, this system therefore achieves higher cutting parameters, which allow the tool to be used even more economically and efficiently.
The S100 cutting insert is available with cutting widths of 2.5 mm, 3 mm and 4 mm. Where hard-to-cut materials are concerned, the AS45 carbide grade and the .EN chipbreaker geometry ensure good chip flow with high stability and reliability, even with long machining times and at high temperatures. The HP65 grade with the .3V geometry is specifically designed for grooving and parting off stainless steels. The tool holders are available as square shank holders with direct coolant transfer or coolant transfer via a bolted connection, and as cartridges for the 842 and 845 systems.
The S224 insert with 3 mm wide cutting edge is available in the HP65 grade in conjunction with the .3V chipbreaker geometry. The wear-resistant AlTiN coating is also suitable for grooving and parting off stainless steels. The tool carriers are available as square shank holders with direct coolant transfer, and as cartridges for the 842 and 845 systems.
