Sumitomo Electric Industries, Ltd. (Head office: Chuo-ku, Osaka, President: Osamu Inoue, hereinafter referred to as "our company") has developed and launched the high-precision shoulder milling cutter SEC-WaveMill™ WEZ Modular Type.

In recent years, the severity of the dimensional tolerance and machining quality required in the machining sector has increased. As such, the demand for improvement in wall surface precision and machined surface roughness for cutting tools is growing stronger.

In response to these needs, our company launched the "SEC-WaveMill™ WEZ Type" in April 2019. Recently, we have developed modular tools that can mount the WEZ type insert for high precision and stability in longer tool overhang machining. An indexable head type endmill, utilizing high-precision inserts with cutting edge sharpness, achieves superior wall surface precision and surface finish quality even in long overhang machining. In addition, a total of 36 items in 10 grades with various combinations of different nose radii and new inserts grades were released at the same time. Raising the total number of insert selections to 124 items, covering the various machining requirements in the automotive, aircraft, shipbuilding, industrial machinery, and metal mold sectors.
