TaeguTec has expanded the Chase2Hepta family series of cutters with new right-handed, neutral and wiper inserts which will cover a wide range of applications and considerably save on cutting loads.

Because of its 14 true cutting edges and double-sided 45 degree entry angle, the Chase2Hepta is an economical solution for a competitive world.

The dual usage inserts can be used on both cutter types a screw type cutter for steel machining and a wedge type cutter for cast iron machining at high feed rates. The new line of inserts’ efficient and smooth machining is due to its optimized cutting edges that lower cutting loads during machining.

The sharp –ML geometries of the new right-handed XNMU 0906 ANTR-ML insert with a full length helical cutting edge is perfect for milling steel under unstable machining conditions such as weak fixtures and clamping, long tool overhang and work pieces with weak cross-sections.

Moreover, this right-handed –ML geometry insert reduced cutting loads by as much as 9 percent compared to the –M geometry while machining alloy steel on a 25 kilowatt, BT50 spindle machine.

While machining a high-tempered alloy steel manifold, the XNHU 0906 ANTR-ML with the versatile TT9080 coating grade increased tool life from 12 to 15 pieces while machining at a cutting speed of 144 meters per minute, a table feed of 360 millimeters per minute and depth of cut of 0.5 millimeters. The case study noted that this insert was ideal for smooth machining and offered a small burr size.

The –ML geometry on the newly introduced Chase2Hepta neutral insert, the XNHU 0906 ANTN-ML, is dedicated to cast iron machining in unstable machining conditions. Its sharp and tight chipformer showed up to 11 percent reduction in cutting loads while machining ductile cast iron as compared to the –MM geometry inserts.

This neutral insert, with its TT6080 grade, helped decrease burr size and more than doubled its tool life while machining a cast iron bracket at 157 meters per minute with a 0.06 millimeter per tooth feed rate and a depth of cut at 0.5 millimeters.

For those looking for superior surface finishing in milling applications, TaeguTec also introduced the XNHU 0906 ANTN-W wiper insert which has two right-handed and two left-handed cutting edges.

As for the current geometries, the XNHU 0906 ANTN-MM handles cast iron and general milling, the XNMU 0906 ANTR-M is more suitable for steel and general milling and the XNHU 0906 ANTN-CE, with its ceramic grade, is perfect for high speed machining of cast iron roughing.

By expanding the Chase2Hepta family of cutters, TaeguTec offers a greater amount of versatility for machining different types of materials while its 14 cutting edges lowers machining cost, extends tool life and increases productivity.
