MZG Fillet End Mill System

The performance of MZG Fillet End Mills is meticulously engineered to overcome the inherent weaknesses of standard square end mills while offering enhanced machining capabilities. The fundamental purpose is derived from its signature corner radius design, which dramatically increases structural integrity by distributing cutting forces evenly across a larger area, eliminating the stress concentration points that make sharp corners highly susceptible to chipping.

Our Fillet End Mills are predominantly manufactured from high-quality Tungsten Steel (solid carbide), chosen for its exceptional hardness, high compressive strength, and ability to retain hardness at elevated temperatures. This material foundation ensures cutting edges remain sharp and effective even when machining tough, abrasive materials across hardness ranges from HRC45° to HRC65°.

Advanced Nano Coating technology further enhances performance through multi-layered PVD/CVD coatings that provide increased surface hardness beyond the carbide substrate, enhanced lubricity to reduce friction and heat generation, and thermal barrier protection for high-speed operations. This combination allows specialized machining of hardened tool steels and stainless steel materials.

The radius geometry creates corresponding fillets on workpieces, eliminating sharp internal corners that act as stress risers while producing visibly smoother, higher-quality surface finishes. This is crucial in applications like mold making and aerospace where surface integrity and part strength are paramount considerations.
