The range of face-grooving products offered by Ringwood-based Horn Cutting Tools Ltd (www.phorn.co.uk) has been expanded to include new holder variants for its S224 double-edged system for producing axial grooves with diameters from from 38mm to 1m.

ue to the availability of a wide range of chip-breaker geometries and substrates, this tool system can be easily adapted to the machining application and the workpiece material. Horn has extended its modular concept so that various types of cartridge can be clamped using a single base holder.

Moreover, internal coolant allows direct cooling at the contact zone to prolong tool life and improve chip removal from the groove (coolant supply is via a transfer point on the base holder). The cartridges can also be used on older Horn holders, but without through coolant.

The axial holders are available in the following versions: LAK (left, external); RAK (right, external); LIK (left, internal); and RIK (right, internal). The maximum groove depth is 14mm, and the widths range from 3 to 6mm.
