Sandvik Coromant 5725415 CNMG642-MM 2035 Turning Insert

Product Description

The SANDVIK COROMANT 5725415 is a CNMG-style indexable turning insert designed for general and finish turning operations on CNC lathes and turning centers. Manufactured from solid carbide with a TiAlN and TiN dual-layer coating, this insert delivers wear resistance and thermal stability across a range of workpiece materials. It features an 80-degree diamond shape (Insert Shape Code C), a 3/4-inch inscribed circle, and a 1/32-inch corner radius. The chip breaker geometry is designated MM, suited for medium machining conditions. Licensed machinists and CNC turning specialists install this insert as a direct indexable replacement in compatible toolholders.

This insert is suited for medium-duty turning applications on CNC lathes operating in production and job-shop environments. The CNMG 19 06 08-MM 2035 ISO designation confirms its fit within the CNMG 642 form factor. The 2035 manufacturer grade is optimized for use in conditions requiring a balance of toughness and wear resistance. The clamp and pin holding method makes it compatible with standard CNMG-style negative-rake toolholders used in both roughing and finishing passes depending on depth of cut and feed rate selection.

Key Features

• TiAlN and TiN dual-layer coating for thermal and abrasion resistance
• 80-degree diamond insert shape for versatile turning and light facing operations
• 1/32-inch corner radius for controlled surface finish on medium cuts
• MM chip breaker geometry designed for medium machining conditions
• Clamp and pin holding method for rigid, repeatable seating in the toolholder
• ISO code CNMG 19 06 08-MM 2035 for cross-reference with standard toolholder catalogs

Compatibility

Designed as a direct indexable replacement for CNMG 642-style negative-rake toolholders using clamp and pin insert retention. Specific model compatibility should be verified against the toolholder manufacturer's insert geometry requirements using the ISO code CNMG 19 06 08-MM 2035.

Installation Notes

Installation should be performed by a qualified machinist with the machine spindle fully stopped and the turret locked out per shop lockout/tagout procedures. Seat the insert fully against the toolholder pocket before tightening the clamp; partial seating causes premature edge failure. Inspect the toolholder pocket for wear or debris before indexing to a fresh cutting edge. Follow the toolholder manufacturer's recommended clamping torque specifications for CNMG-style inserts.
