The Korloy MGMN300-M NC3030 is a carbide indexable parting and grooving insert, 3mm in width, used on CNC and manual lathes for parting off and grooving operations. It is used by machine shops running production turning work that need a durable, double-ended insert for heavy parting on bar stock. SAN Tools stocks the Korloy MGMN300 range from our branches in Dubai (Al Quoz), Sharjah and Ajman, with UAE-wide delivery.

How to choose
- Confirm your holder series (MGEHR/L, MGIVR/L or MGFHR/L) accepts a 3mm-width MGMN insert before ordering.
- Use the M-style chipbreaker for medium feed rates on steel; for very deep or heavy-load parting, ensure your setup is rigid enough for the recommended bar diameter range.
- Keep spare inserts on hand for production runs, as double-ended inserts still require periodic indexing and replacement.
- Match coolant and feed rate to the NC3030 grade's recommended cutting parameters for best tool life.
