The HP65-grade S224 indexable insert with through tool coolant, featuring the 3V geometry and a 3 mm (.118”) grooving width, is a new addition to the HORN range. Its wear-resistant AlTiN coating is specially designed for grooving and parting off stainless steels. The cutting insert with 3 mm (.118”) cutting width and an internal coolant supply expands the areas of application of an existing and strong tooling system.

The coolant jet acts directly on the cutting zone, ensuring optimum cutting conditions. The funnel-shaped nozzle creates a coolant jet, which supports chip forming and thus reduces the chance of chip build-up. This type of internal cooling largely prevents the formation of built-up edges and fractures of the cutting edge. Unlike conventional cooling methods, this system enables higher cutting parameters, which allow the tool to be used more cost-effectively.

The square shank holder with internal cooling is available in dimensions of 16 x 16 (.630 x .630”), 20 x 20 (.787 x .787”) and 25 x 25 mm (.984 x .984”), in a right-hand and left-hand design. Coolant is transferred via a supply port in the bottom of the square shank. The holders are compatible with the relevant VDI supports and allow inserts to be replaced easily with a high level of repeatability and accuracy.
