Sandvik Coromant 5725136 CNGA432 Ceramic Turning Insert

Product Description

The SANDVIK COROMANT 5725136 is an uncoated ceramic turning insert designed for high-speed hard turning and interrupted-cut machining operations. Carrying the CNGA432 T0320WG 6190 designation, this insert features an 80-degree diamond shape with a 0 degree relief angle and a clamp-and-pin holding method. The manufacturer grade is 6190, suited to demanding cutting conditions where ceramic tooling is specified. With a 0.5000-inch inscribed circle and a 1/32-inch (0.0313-inch) corner radius, this insert is sized for precision material removal. A licensed machinist or CNC tooling technician installs it in compatible CNGA-style toolholders. It is sold individually, with a minimum order quantity of 10 units.

This insert is applied in turning centers and CNC lathes where ceramic grade tooling is required, typically for high-temperature alloy, hardened steel, or cast iron finishing passes at elevated surface speeds. The chip breaker designation A and ISO code CNGA120408T01020WG 6190 identify the geometry for tool crib and program setup reference. It is appropriate for external turning operations where tight tolerances and surface finish are prioritized. Installation is performed by machinists and CNC setup technicians working with CNGA-compatible toolholders.

Key Features

• Uncoated (bright) ceramic insert material for high-speed cutting applications
• 80-degree diamond insert shape (shape code C) for versatile turning geometry
• 1/32-inch (0.0313-inch) corner radius for controlled surface finish
• Clamp and pin holding method for secure seating in compatible toolholders
• ISO code CNGA120408T01020WG 6190 for precise grade and geometry identification
• Tolerance code G and clearance code N per standard insert classification

Compatibility

Designed for use in CNGA-style toolholders accepting a 0.5000-inch inscribed circle, 3/16-inch thick diamond inserts with clamp and pin retention. Verify toolholder pocket specifications against the CNGA432 insert geometry before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use a torque wrench calibrated to the toolholder manufacturer's clamping specification for the clamp screw. Inspect the toolholder pocket and locating pin for wear or debris before seating the insert, and confirm the insert is fully seated before resuming cuts.
