Dormer Pramet has recently expanded its indexable offer for turning and milling applications. Designed for rough forging and castings, the new Pramet HR2 chip breaker features a positive, stable geometry for improved tool life and performance. The single-sided inserts are ideal for working in steels, cast irons and stainless steels. The HR2 delivers increased productivity with reliable chip formation and evacuation at high feeds.
The NMR chip breaker is another addition to the range – a double-sided chip breaker specifically designed for stainless steel operations. This new geometry joins the current double-sided range, which includes the NM (medium turning) and NF (finish turning) chip breakers.
The new W-FM and W-NM wiper inserts feature a positive front land for smooth machining. Single-sided positive inserts with the W-FM positive geometry are suitable for stainless steel and steels. The double-sided negative inserts with the W-NM highly positive geometry are ideal for machining stainless steel and low carbon steels.
The newest milling grade is the M6330, developed specifically to achieve longer cutting edge durability and reliability in stainless steels and DTMM with and without coolant. It is best suited for adverse cutting conditions, including interrupted cutting, the M6330 is now available with many of Pramet’s inserts, including the ADMX, HNGX, LNGX, LNMU, OEHT and numerous other styles.
