Sumitomo Electric Industries, Ltd. (Head office: Chuo-ku, Osaka, President: Osamu Inoue; below, "our company") has expanded and launched insert grades for SEC-Grooving Tool GND series, internal boring holders GNDIS type as of November 2024.

Grooving, widely used for machined parts such as aerospace components and automotive parts, has the entire cutting edge in contact with the workpiece during machining, resulting in high load and also high temperature on the cutting edge. Furthermore, demand for machining of exotic alloys such as nickel-based alloys is rising yearly, with increasing needs for grooving tools with stable and long tool life.

In response to these needs, our company has expanded our lineup of SEC-Grooving Tool GND series by applying the coated carbide grades for exotic alloys AC5015S and AC5025S to inserts for internal boring holders GNDIS type.

1. Features
(1) Achieves long and stable tool life in machining of exotic alloys
Coated carbide grades for exotic alloy turning AC5015S and AC5025S adopt our proprietary Absotech™ Bronze PVD* coating on dedicated carbide substrates for significant improvement in wear resistance and fracture resistance for machining exotic alloys.

(2) High-rigidity design reduces vibration
Through the use of a high-rigidity mono-block structure design and die steel, the GNDIS type holder reduces vibration during internal grooving, realising high-efficiency machining and reduced power consumption.

2. Lineup
Insert (Grade: AC5015S): 4 Cat. Nos.
Insert (Grade: AC5025S): 4 Cat. Nos.

3. Sales Plan
14 million JPY/year in the first year, 29 million JPY/year after 2 years

4. Standard Price
Insert: 2,110 to 2,250 JPY (excluding tax)/pc

*PVD (Physical Vapour Deposition): A coating method of physically depositing a thin layer on the surface of the target material in the vapour phase.
