Xcel insert – high productive machining into a corner
A tooling solution for semi-rough turning
into shoulders, combines a host of design
advantages combing the benefits of a
square and rhomboid insert into one single
tool:
• reduced notch wear and increased feeds
compared to rhombic inserts.
• reduced radial forces and constant chip
thickness compared to round inserts.
• greater accessibility in confined spaces
than square inserts, in addition to having
the ability to machine in two directions,
and provide a known offset point for pre-
cise positioning of the cutting edge.
Longer tool life, secure machining, and
increased cutting data – all the best pos-
sible advantages are available from a single
tool.
Two chamfer sizes are available, to suit
depths of cut up to 2.7 mm in intermediate
stage machining, ISM. They are offered in
several grades, all proven performers in ISO
S materials.
