Sandvik Coromant 8432049 Cnmg Turning Insert 1205 Carbide

Product Description

The SANDVIK COROMANT 8432049 is a CNMG-style indexable turning insert designed for high-performance metal cutting operations. Built from carbide substrate and finished with a PVD AlTiN coating, this insert is engineered to handle demanding turning applications, particularly in stainless steel and super-alloys including titanium. The ISO designation is CNMG 12 04 08-SM 1205, with the SM chip breaker geometry optimizing chip control and surface finish across a range of cutting parameters. With 4 cutting edges per insert and a diamond 80-degree insert shape, it delivers consistent performance in both roughing and finishing passes.

This insert is suited for CNC lathe and turning center operations in job shops, production machining facilities, and aerospace or medical component manufacturing environments where stainless steel and titanium alloys are common workpiece materials. The neutral hand orientation makes it adaptable to a wide variety of toolholder setups. Installation is performed by licensed machinists and CNC operators working with compatible CNMG toolholders using screw or clamp holding methods.

Key Features

• PVD AlTiN coating for improved wear resistance and heat management in stainless and super-alloy cutting
• SM chip breaker geometry optimized for controlled chip formation and reduced built-up edge
• Diamond 80-degree insert shape (CNMG) provides strong cutting edge geometry with 4 usable edges
• Inscribed circle of 0.5000 inches (12.70 mm) and corner radius of 0.0313 inches (0.79 mm)
• Neutral hand orientation compatible with a broad range of CNMG toolholders
• Screw and clamp holding method for secure, repeatable insert indexing

Compatibility

Designed as an OEM-style replacement for CNMG 12 04 08-SM 1205 tooling setups. Compatible with toolholders accepting CNMG inserts with a screw or clamp holding method. Primary workpiece material is stainless steel; secondary workpiece material is super-alloys and titanium.

Installation Notes

This insert is installed and indexed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torx or hex key for the clamping screw and do not overtighten. Inspect the toolholder seat and shim for damage before seating a new insert.
