ARNO SA Parting and Grooving tools... the only system you will need

Parting and Grooving, the ARNO USA Way

Through Coolant Parting and Grooving

Parting and Grooving Perfection

With diameter capacities up to 4.0” and widths from .059” to .394”, the SA Parting and Grooving System will be the only parting system you’ll need. Right, left, and neutral approaches give you options for pip controls, making this range of inserts necessary for completing the program.

Patented ACS2 Coolant Delivery

In the tooling industry, you can’t get more coolant to the cut zone than with the patented ARNO ACS2 coolant delivery system. ACS2 delivers through-the-tool coolant under both the clamp and the flank of the insert.

Multiple Adaptations to Your Machine

Machine-specific, industry-standard back ends adapt your modular MSA parting blade right to your machine’s turret. Couple the rigidity of these adaptors with our patented ACS2 coolant delivery system to achieve unbeatable performance and process stability on your parting station.
