AC810P/AC820P/AC830P Grades for Steel

The ultra hard and ultra smooth Super FF coating of these next generation steel turning grades improves both heat and wear resistance for increased speeds and feeds. AC810P leads off the group as a high speed finishing grade for steels and stainless steels.Together with the AC820P and the AC830P machine applications ranging from finishing to general purpose to heavy roughing in steel and stainless steel.

AC410K/AC420K Grades for Gray and Ductile Irons

Featuring Super FF Alumina and Super FF TiCN coatings, the AC410K grade offers excellent wear resistance in continuous to light interrupted machining of gray and ductile cast iron and the AC420K is a perfect partner roughing grade. The AC410K's tool life is at least doubled that of conventional cast iron grades, and it is capable of covering medium to high-speed machining applications. The AC410K and AC420K grades are available in positive and negative insert styles.

YB100 Coated Carbide Grades

Featuring a unique substrate, edge honing and fine TiCN CVD coating, the YB100 coated carbide grade is the most versatile of its kind in the metal cutting industry. The YB100 can go from finish turning steels and stainless steels to roughing cast iron.

AC510U/AC520U Grades for Exotic Materials

With up to 1,000 layers of TiAIN and AlCrN coatings alternately stacked, higher speed capabilities and greater wear resistance can be achieved with the new AC510U/AC520U. The AC510U grade is capable of finish machining of exotic materials, while the AC520U grade is superior in roughing and medium cut machining applications. The grades are available in both molded and ground insert types.

T2000Z Grade Cermet Finishing

Our T2000Z grade is the perfect solution for applications where cermet is too brittle and carbide wears rapidly. Ideal for high speed finishing in steel applications, it features very high heat resistant properties and superior toughness. The T2000Z is coated with Sumitomo's unique ZX coating technology for an ultra smooth cutting edge that provides superior surface finishes. Other features of ZX Technology include high hardness, excellent oxidation resistance and excellent peeling resistance. The T2000Z 's new coating and substrate reduce both tool wear and breakage. The T2000Z is available in negative and positive rake geometries with our high quality chip breakers.
