Chip Breaker and Grade for Heavy Roughing

Pramet has launched a new Chip Breaker and Grade for heavy roughing applications. The HR2 geometry expands Pramet’s range of single-sided inserts for machining a wide range of materials including steels, cast irons and stainless steel. Designed for rough forgings and castings, such as cylinders, shafts and large pins, the HR2 features a positive, stable geometry for improved tool life and performance. Its cutting edge design and wide peripheral land promote increased productivity, while offering reliable chip formation and evacuation at high feeds (0.7 mm/rev). This promotes a continuous production process with less machine downtime, resulting in a more cost-effective operation. The new chip breaker compliments the existing HR insert, which covers semi-roughing to roughing applications. HR2 is available with a new turning grade – T9226 – also launched recently. The versatile T9226 grade achieves impressive results in heavy roughing and peeling operations. For these applications it replaces Pramet’s existing 6630 grade. Providing high insert reliability and durability in adverse cutting conditions, the T9226 offers greater cutting edge strength. This is primarily due to a new functional gradient substrate, which contains a higher amount of cobalt binding and finer grain structure. Pramet is a product brand of Dormer Pramet.
