Series Expansion - "Mono-Block Holder" Added to the "GY Series" Grooving System

August 5, 2014

Mitsubishi Materials Corporation, Advanced Materials & Tools Company (President - Teruhiko Masuda, Headquarters: 1-3-2 Otemachi,Chiyoda-ku,Tokyo) has launched a new mono-block type holder for GY series grooving system.

The existing GY Series has received a favorable reception as a breakthrough in grooving tools that offers the ultimate in rigidity with a unique clamping technology called TRI-LOCK. This modular type holder (1) system realizes high efficiency machining.

A newly developed mono-block type holder with zero offset between the holder and cutting edge has been released to complement the existing range.

Features of the zero offset mono-block holder

1.The tool offset compensation can be easily set because the offset between the side of the holder and the cutting edge is zero mm.

2.Mono-block type holders with high rigidity can improve surface finishes and prevent vibration.

3.The price of mono-block holders is less than modular types, although the application range is limited compared to modular types that have interchangeable parts.


(1) Modular type holder
A modular type holder is a tool that is made from separate but modular parts that are interchangeable between tools. This means in the event of damage, or if another type of tool is required, it is possible to replace only a single part rather than the whole tool. This provides a high level of convenience and cost effectiveness compared to mono-block type holders.
