As Seen In Production Machining

Turning grades

AC4000K Turning Grades Provide Double the Wear Resistance
Sumitomo Electric Carbide Inc.’s AC4010K and AC4015K series turning grades for cast iron feature technologies that result in a long and stable tool life and crystal orientation control technology that provides double the wear resistance during high-speed machining.

Small parts machining grades

AC1030U Grade Features Absotech Bronze PVD Coating
Sumitomo Electric Carbide Inc.’s AC1030U high precision small parts machining grade provides resistance against adhesion and microchipping for surface finishes.

Tangential milling cutter

TSX Series Tangential Milling Cutter Handles High Feed Rates
Sumitomo Electric Carbide Inc.’s TSX series tangential milling cutter is designed for efficient shoulder milling and is engineered with a tough and sharp cutting edge for stable, highly efficient machining at high feed rates. 

Sumitomo's BNC2010 grade

BNC2000 Series CBN Grades Perform with Accuracy and Productivity
A newly developed CBN substrate coated with a TiCN layer achieves excellent surface finish, while reducing wear, the company says.

Sumitomo Stainless Steel Turning Grades Improve Wear Resistance
Sumitomo Electric Carbide Inc.’s AC6030M and AC6040M turning grades for machining stainless steels feature the company’s Absotech grade coating that improves wear resistance, adhesion resistance and fracture resistance, which extends tool life, reducing the cost per part, according to the company.

These two signed a licensing agreement under which Sumitomo Electric will provide and support Kennametal’s KM4X spindle solution to its customers globally.


BN7000 Turning System for Cast Iron Machining
Sumitomo Electric Carbide Inc.’s BN7000 turning system for the machining of cast iron possesses CBN particles that are densely sintered for the maximum CBN content possible, resulting in high wear and breakage resistance.

Things are Hot in Japan
Your intrepid reporter just returned from a 2-week romp around Japan, meeting with some of that country’s premier metalworking companies.

BN7500 CBN Grade Machines Powdered Metal
Sumitomo Electric Carbide Inc.’s uncoated BN7500 CBN grade is for high precision and high efficiency machining of powdered metal.

Sumitomo Opens Tool Engineering Center
Sumitomo Electric Carbide Inc. has announced the grand opening of its Tool Engineering Center (TEC) and plant expansion in New Berlin, Wisc.

Sumitomo MESI chipbreaker

Chipbreaker for Medical Machining
MESI, Sumitomo Electric Carbide Inc.’s new chipbreaker for Swiss and medical part machining, has a high-precision cutting edge, with CCGT, DCGT and VCGT geometries available and produces a range D.O.C. (2.0 mm-6.0 mm) for bar feeder machines.

CBN Grade for Hardened Steel
Specifically designed for turning die steels and bearing steels with hardnesses of 50 HRc and higher, the BN2000 provides high wear resistance and robust toughness.

Coated Carbide Turning Grade for Cast Iron Roughing
ISO classified as a K20 grade, the AC420K is designed to perform exceptionally well in cast iron roughing applications involving medium to heavy interruptions.

Turning of Steels and Stainless Steels
The Super FF (Fine and Flat) coating on the company’s new insert grades, AC820P and AC830P, is wear resistant and reduces the possibility of chip adhesion because of its smoothness. 

WDX indexable drills

Indexable Drill for Large-Diameter Hole Drilling
The WDX indexable drill series from Sumitomo Electric Carbide Inc. for large-diameter hole drilling not only accurately drills holes, but can also perform operations such as turning and boring, the company says.


Grade Achieves Interrupted Steel Turning
The AC830P for interrupted steel turning by Sumitomo Electric Carbide combines a tough substrate with a newly designed Super FF coating structure to substantially increase the wear resistance compared to conventional P30 material grades. The grade's wear resistance not only exceeds conventional P30 coated carbide g


Grades For Turning Exotic Materials
The Super ZX multi-layered coating on the new grades AC510U and AC520U make them especially useful for roughing, finishing and medium cut machining of super alloy materials. The coating consists of ultra-thin layers of TiAlN and AlCrN, alternately stacked up to 1,000 layers.
