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 sur-
face 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, see page 78.
