Product Overviews


General Introduction on Carbide Grooving Inserts 


Carbide indexable groove cutting tools developed by CTRI can be adapted to varieties of groove profile processing and demonstrate high accuracy, better efficiency and short lead time etc.


According to different parts to be processed, we divide the grooving tools as inner hole groove inserts, cylindrical groove inserts, and face groove inserts.


Based on the groove structure, we divide inserts into flat groove insert and profile grooving insert; also, products can be divided into on-edge and horizontal design in terms of inserts positioning.


The groove width can be 0.5~3.5mm and depth is 0.5~4mm, and CTRI groove inserts can be used to machine inner hole as small as 8mm. non-standard cutting tools based on customer’s special requests are available.
