■ Characteristics
For the grooving insert TGA Type, the SumiTurn B-Groove (BF Type)
with chipbreaker that solves the chip control problem now has a
whole series.


■ Features
● Implements good chip control in a wide range of grooving.
● Traverse machining at the groove base is a countermeasure for chip control
● Expanding from 14 items for snap ring grooving, we have 1.4 mm to 4.5 mm edge widths (for a total of
60 items) in stock.
● From steel and stainless steel to non-ferrous metal, it enables the long tool life of various work materials.
