The Dormer Pramet milling assortment for die and mold has grown with several introductions, including the double-sided Carbide Inserts Pramet SNGX11 insert for high-feed milling with up to 0.07" DOC. A strong main cutting edge ensures a high level of durability and process security, especially when machining corners inside a pocket. With eight cutting edges, the square-shaped SNGX11 also represents an extremely economical solution.

Suitable for copy milling, helical interpolation, ramping, progressive plunging and facemilling, the SNGX11 is available in two geometries. M is for machining steel, but also hardened steel and cast iron. MM provides a smoother cut and is more suitable for stainless steel, soft steel and superalloys. 

The range is supplemented by the new SSN11 cutter, available in diameters from 1.26" to 4.92" with intermediate sizes for die and mold applications. All cutters feature a special through-coolant design to Face Milling Inserts further improve process security and a high overhang to support deep milling up to 10xD.

Meanwhile, there are also new additions to the Pramet ADMX07 milling program with a new F geometry for finishing and semifinishing applications. This sits alongside the existing M, FA and HF geometries and targets light machining of stainless steel and low carbon steels.

Suited to vibration sensitive machining, the chipbreaker features a highly positive geometry with narrow peripheral land. This reduces chatter and enables a smooth cutting action without burrs on the machined wall.

It also supports lower cutting forces, which not only reduces energy consumption but also prevents workhardening, meaning increased durability and longer tool life.
