High Feed Milling Inserts – Maximum Productivity Roughing

Ultra-High Feed Milling Inserts

High feed milling inserts are engineered for extremely high feed rates (up to 3–4 mm/tooth) with very shallow depth of cut. This combination delivers the highest metal removal rate (MRR) among all milling inserts, making them ideal for fast roughing of large stock removal.

Amony high feed series includes 12 popular models:

• HNMG, SNMU, SNMX – Classic high feed geometry

• LNKT, LNMU, LNGU – Long cutting edge for higher stability

• LNKX, LPGT, LOGU – Large diameter high feed

• WNMU, XNEX, XNMU – Advanced high feed designs
