Sandvik Coromant 7080698 Turning Insert CCMT432-PM 4335

Product Description

The SANDVIK COROMANT 7080698 is a solid carbide turning insert in the CCMT432-PM geometry, part of the CoroTurn 107 series. It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous and interrupted steel turning operations. The insert carries an 80-degree diamond shape (C), a 7-degree relief angle (clearance code C), and a 1/32 inch (0.0313 inch) corner radius. The inscribed circle measures 1/2 inch (0.5000 inch) and insert thickness is 3/16 inch (0.1875 inch). The PM chip breaker geometry is engineered for steel cutting applications. Screw clamping is the designated holding method. Licensed machinists and CNC turning specialists are the primary installers of this insert.

This insert is designed for external turning on steel workpieces, corresponding to ISO material group P. It suits light to medium roughing and finishing passes on CNC lathes and turning centers where consistent chip control and edge security are required. The ISO designation for this insert is CCMT 12 04 08-PM 4335. The 4335 grade and CVD coating combination targets steel components where tool life and surface finish consistency are priorities. It is sold individually with a minimum order quantity of one.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal protection on steel
• 80-degree diamond insert shape (CCMT) with neutral hand orientation
• PM chip breaker geometry suited for steel turning in ISO material group P
• 1/32 inch corner radius for a balance of edge strength and surface finish
• Screw clamping (hole diameter 0.2165 inch) for secure, repeatable seating in compatible toolholders
• Two cutting edges per insert

Compatibility

Designed for use in CoroTurn 107 series toolholders that accept CCMT432 (ISO: CCMT 12 04 08) screw-clamp inserts. Consult the toolholder documentation to verify seat geometry and clamping screw compatibility before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing the insert. Use the correct Torx or hex key to tighten the clamping screw to the toolholder manufacturer's specification — do not overtighten, as this can fracture the carbide. Inspect the insert pocket seat for chips or debris before seating the new insert to ensure proper contact and runout.
