Sumitomo 196CCGY Turning Insert WNMG431EEF AC6030M Carbide

Product Description

The SUMITOMO 196CCGY is a solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured to ANSI code WNMG431EEF and ISO code WNMG080404N-EF, it carries the AC6030M grade with a CVD coating for extended tool life under demanding cutting conditions. The insert features an 80-degree trigon (W) shape with a neutral hand orientation and a negative rake geometry. With a 1/2-inch inscribed circle and a 1/64-inch corner radius, this insert is suited for general-purpose turning operations where surface finish and edge consistency are critical. Machinists and CNC operators install this insert in compatible toolholders as a precision cutting consumable.

The 196CCGY is engineered primarily for turning stainless steel workpieces, making it a go-to insert for shops handling austenitic or duplex stainless grades. The EEF chip breaker geometry is optimized for controlling chips in these difficult-to-machine materials. It fits into WNMG-style insert seats in standard turning toolholders and boring bars. This insert belongs to the Sumitomo TN series and is held in place by a clamp and pin clamping method, which is standard on most WNMG-format toolholder bodies. Sold individually per package with a minimum order quantity of 10 pieces.

Key Features

• AC6030M grade with CVD coating for wear resistance on stainless steel
• 80-degree trigon insert shape (ANSI WNMG431EEF) with negative rake geometry
• EEF chip breaker designed for chip control in stainless steel turning
• 1/64-inch corner radius for balanced edge strength and surface finish
• Clamp and pin holding method for secure seating in compatible toolholders
• Compliant with ANSI and ISO 13399 standards for insert identification

Compatibility

Designed as a direct-fit replacement for WNMG431-style insert seats in standard WNMG-format turning toolholders and boring bars. Compatible toolholders must accept a clamp and pin clamping method with a 0.2031-inch hole diameter.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before changing inserts. Seat the insert firmly against all pocket walls before tightening the clamp to ensure proper indexing and edge engagement. Inspect the insert pocket for wear or debris prior to installation, as a damaged pocket will reduce tool life and dimensional accuracy.
