For grooving applications we offer dedicated geometries with the CoroCut system, e. g. GF, GM, TF and TM. These geometries are designed to give specific benefits in both radial and face grooving, and other machining methods such as external and internal multiple grooving and plunge turning.
The different geometries are suitable for high or low feed machining.
For circlip grooving, CoroThread 254 is the first choice for productive solutions.

Single cut grooving
Single cut grooving is the most economical and productive method of producing grooves and is possibe for use on insert widths up to 8 mm.
The GF geometry precision insert has a width tolerance of ±0.02 mm. GF is our low feed choice (0.02–0.25 mm/r) and GM is intended for tougher machining e.g medium feed (0.04-0.30 mm/r).
The TF geometry is designed with wipers on the side in order to generate extreme high surface quality on the side of the groove.
The stable CoroCut system makes it ideal to chamfer corners.
Choose correct width from our wide standard programme or order an insert that directly corresponds to the actual groove with our Tailor Made programme.
