Sandvik Coromant 5725044 Turning Insert CCMT432-WM 1115

Product Description

The SANDVIK COROMANT 5725044 is a solid carbide turning insert from the CoroTurn 107 series, designed for precision external and internal turning operations on CNC lathes and turning centers. It carries an ANSI insert code of CCMT432 and an ISO designation of CCMT 12 04 08-WM 1115. The insert features a PVD-applied TiAlN and AlCr2O3 dual-layer coating optimized for high wear resistance and moderate toughness. The WM chip breaker geometry targets medium machining conditions on stainless steel and superalloys. With a 0.5 inch inscribed circle and a 1/32 inch corner radius, this insert suits fine-to-medium finishing cuts where surface integrity and tool life are the priority.

This insert is intended for machining stainless steel (ISO material code M) as its primary workpiece material, with secondary suitability for superalloys and titanium (ISO material code S). It is a neutral-hand insert, making it compatible with a broad range of right-hand and left-hand tool holders designed for the CCMT432 seat geometry. The wiper edge geometry provides improved surface finish at standard feed rates compared to conventional inserts. Applications include shaft turning, bore finishing, and contour turning on components commonly found in aerospace, medical, and process-industry manufacturing where stainless and nickel-based alloys are standard materials.

Key Features

• PVD-coated TiAlN and AlCr2O3 dual-layer finish for high wear resistance on stainless and superalloy workpieces
• WM chip breaker geometry engineered for medium machining — controls chips effectively at moderate feeds and depths
• Wiper edge included — delivers improved surface finish without reducing feed rate
• 80-degree diamond (rhombic) insert shape with positive side clearance for reduced cutting forces and vibration
• Neutral hand orientation provides flexibility across a wide range of CCMT432-compatible tool holders
• Screw-mount holding method ensures repeatable insert indexing and secure clamping under interrupted or continuous cuts

Compatibility

Designed as an OEM-style replacement turning insert for tool holders with a CCMT432 (ISO CCMT 12 04 08) insert seat; verify holder specifications for correct clearance angle and clamping method before installation.

Installation Notes

This insert is installed by a machinist or tooling technician using the appropriate torque wrench on the clamping screw — always follow the tool holder manufacturer's torque specification for the screw size used. Ensure the machine spindle is fully stopped and the lathe is locked out before indexing or replacing inserts. Inspect the insert pocket and seating surfaces for chips or debris before seating a new insert, as contamination can cause premature edge failure or poor surface finish. Dispose of worn carbide inserts according to applicable local regulations for cutting tool waste.
