In Booth W-2464, Dormer Pramet (Elgin, IL) displays their indexable offer for turning and milling applications with an expanded line of the most reliable and efficient cutting tool options designed to provide confidence in application. Their new products for turning include the Pramet HR2 chip breaker for rough forging and castings that 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 of a double-sided chip breakers specifically designed for stainless steel operations. This new geometry joins the current double-sided range, which includes the NM (medium turning) and NF (finishing turning) chip breakers. The new W-FM and W-NM wiper inserts feature a positive front land for smooth machining. In straight turning and facing operations, the smoothing effect of the wiper results in improved quality of surface roughness. 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. With impressive results, the versatile T9226 is the newest grade and replaces the Pramet 6630 grade in heavy roughing and peeling operations. With reduced adhesion to the workpiece and greater cutting edge strength, the T9226 grade delivers operational reliability and longer tool life. New products for milling include the M6330 milling grade developed specifically to achieve longer cutting edge durability and reliability in a range of DTMM with and without coolant. Particularly suited to adverse cutting conditions, including interrupted cutting, the M6330 is now available with many of Pramet’s most popular inserts, including the ADMX, HNGX, LNGX, LNMU, OEHT and numerous other styles.
