Sandvik Coromant 5756882 Turning Insert Wpmt Carbide

Product Description

The SANDVIK COROMANT 5756882 is a solid carbide turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. Part of the CoroTurn 111 series, this insert carries the ISO designation WPMT 04 02 04-MF 1125 and features a PVD-applied TiAlN and AlCr2O3 dual-layer coating for extended tool life and heat resistance at the cutting edge. The trigon insert shape provides three usable cutting edges, the MF chip breaker geometry is optimized for finishing cuts, and the neutral hand orientation suits standard right-hand toolholders. Insert length is 0.1553 inches with a 1/4-inch inscribed circle and a 1/64-inch corner radius.

This insert is rated primarily for stainless steel (ISO material code M) and secondarily for superalloys and titanium (ISO material code S) — workpiece materials common in aerospace, medical device, chemical processing, and marine component manufacturing. The MF chip breaker geometry targets finishing and semi-finishing passes where tight surface finish tolerances and controlled chip evacuation are critical. Screw clamping secures the insert in compatible toolholders, making indexing straightforward during production runs.

Key Features

• PVD-coated TiAlN and AlCr2O3 dual-layer coating for heat and wear resistance
• Three cutting edges per insert — trigon (W) shape maximizes value per insert
• MF chip breaker geometry optimized for finishing cuts on stainless steel and superalloys
• Screw-lock insert holding for secure, repeatable seating in toolholders
• Neutral hand — compatible with standard right-hand turning applications
• ISO designation WPMT 04 02 04-MF 1125 for direct cross-referencing

Compatibility

Designed for use in CoroTurn 111 series toolholders accepting WPMT-style inserts with a 1/4-inch inscribed circle and screw clamping. Verify toolholder pocket dimensions against the ISO insert code WPMT 04 02 04-MF 1125 before installation.

Installation Notes

Installation is performed by machining technicians or toolroom personnel on powered-off, locked-out CNC turning equipment. Use a calibrated torque screwdriver rated for the toolholder manufacturer's specified clamping screw to seat the insert without over-torquing the pocket. Inspect the insert pocket for chips or debris before indexing to a fresh cutting edge. Always index or replace inserts with the machine fully stopped and the spindle locked.
