Sandvik Coromant 5726194 Turning Insert CPMT21.52-MM 2025

Product Description

The SANDVIK COROMANT 5726194 is a CPMT-style solid carbide turning insert in the CoroTurn 111 series, designed for precision metal-cutting operations on CNC lathes and turning centers. The insert carries a multi-layer CVD coating of TiCN, Al2O3, and TiN, which builds wear resistance, thermal stability, and edge life on demanding workpiece materials. With an 80-degree diamond shape, a 0.0313-inch corner radius, and a neutral hand orientation, it suits a range of external turning, facing, and profiling passes. The MM chip breaker geometry is optimized for stainless steel applications where chip control and cutting-edge security are critical priorities for production machinists and toolroom technicians.

This insert is sized for use in CoroTurn 111 toolholders that accept CPMT-style inserts with a 1/4-inch inscribed circle. The MM chip breaker geometry and grade 2025 designation make it particularly well suited for continuous to light interrupted cuts on stainless steel and similar ISO M workpiece materials. It is a screw-held insert, making it a straightforward swap in compatible CPMT toolholder pockets on both manual and CNC turning machines. This SKU is sold individually with a minimum order quantity of 10 units per order.

Key Features

• Multi-layer CVD coating: TiCN, Al2O3, and TiN for extended tool life on stainless steel
• 80-degree diamond insert shape with 11-degree relief angle (clearance code P) for good accessibility on external profiles
• MM chip breaker geometry engineered for reliable chip control on ISO M materials
• Neutral hand orientation works in both left- and right-hand CPMT toolholder setups
• Screw-held mounting method (tolerance code M) for secure, repeatable seating in the pocket
• 2 cutting edges per insert for cost-effective edge utilization

Compatibility

Designed for use in CoroTurn 111 series toolholders that accept CPMT insert style with a 1/4-inch inscribed circle and screw-held clamping. ISO code CPMT 06 02 08-MM 2025 can be used to cross-reference compatible toolholder pockets.

Installation Notes

Installation is performed by a machinist or toolroom technician on a powered-down, de-energized machine with the spindle locked. Remove the clamping screw, lift out the worn insert, seat the new insert fully into the pocket, and torque the screw to the toolholder manufacturer's specified value. Inspect the cutting edge and chip breaker orientation before resuming cuts. Handle carbide inserts with care to avoid chipping the cutting edge during indexing.
