Paul-Horn Cutting insert designed for grooving and parting of stainless steels

Editor: Barbara Schulz

Germany – The HP65-grade S224 cutting insert with internal cooling, featuring the 3V geometry and a 3 mm grooving width, is a new addition to the Horn range.

The company said that the coolant jet acts directly on the cutting zone of the HP65-grade S224 cutting insert to allow for optimum cutting conditions at this point.

Its wear-resistant AlTiN coating is specially designed for grooving and parting off stainless steels, Horn said. The cutting insert with 3 mm cutting width and an internal coolant supply expands the areas of application that the cutting inserts from the S224 range have been suitable for up to now.

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

The square shank holder with internal cooling is available in a right-hand and left-hand design. Coolant is transferred via a slot at the bottom. The screw clamping device for the cutting inserts benefits from a stop to allow inserts to be replaced easily with a high level of repeat accuracy, Horn said.
