Sandvik Coromant 5735399 Grooving Insert Corocut Xs

Product Description

The SANDVIK COROMANT 5735399 is a solid carbide grooving insert in the CoroCut XS series, designed for precision grooving operations on small-diameter parts and tight-clearance applications. It carries a TiAlN/TiN PVD coating applied over the carbide substrate, which extends tool life under dry and semi-dry cutting conditions. The insert has a 0.50 mm cutting width, a maximum depth of cut of 1.30 mm, and a neutral rake angle of 6 degrees. The MAG chip breaker geometry controls chip formation at these narrow widths. Machinists and CNC tool setters working on Swiss-type lathes or small-part turning centers are the primary users of this insert.

This insert is suited for grooving, parting, and shallow-groove profiling on small workpieces where standard-width inserts cannot reach. The CoroCut XS series is built around compact insert seats, making it applicable in confined radial and axial grooving scenarios. The right-hand cutting orientation defines tool approach direction and must match the holder designation before ordering. The MAG insert style and size 3 seat are defining fitment parameters. Multi-use capability allows the insert to be repositioned within compatible toolholders where seat geometry permits.

Key Features

• Solid carbide substrate with PVD-applied TiAlN/TiN coating for wear resistance
• 0.50 mm cutting width suits micro-grooving and small-part parting operations
• 1.30 mm maximum depth of cut with a depth-of-cut range up to 2.00 mm
• MAG chip breaker geometry controls chip evacuation at narrow cutting widths
• Neutral rake with a 6-degree rake angle reduces cutting forces on small-diameter stock
• Right-hand insert orientation; ISO code MAGR 3 050 1025
• Multi-use designation allows repositioning in compatible insert seats

Compatibility

Designed for use in CoroCut XS series toolholders requiring an insert seat size 3 and the MAG insert style. Holder selection must match the right-hand cutting orientation and the MAG seat geometry. Verify ISO code MAGR 3 050 1025 against the toolholder specification before installation.

Installation Notes

Installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine powered down and the spindle locked. Use the torque key specified for the CoroCut XS clamping system; do not use an open-end wrench to seat the insert. Inspect the insert pocket for debris or wear before seating a new insert, as contamination at this scale directly affects runout and surface finish. Confirm cutting direction and holder orientation match before resuming operation.
