Ingersoll is introducing a new RA chipbreaker for heavy rough machining of large sized parts. RA chipbreaker inserts maximize tool life due to decreased cutting forces enabling excellent chip breaking while stable edge structures make for easier rough and semi-machining processing. RA chipbreaker is now available in RCMX type guaranteeing excellent tool life and chip breaking under high and low cutting conditions. Features include improved stability and machining through real negative and positive cutting edges on the rake angle, increased tool life by minimizing cutting resistance with optimized chip groove geometry, excellent tool life due to superior cutting edges minimizing heat generation during machining and superior chip control is applicable to extensive application range.
