Walter 6955645 Turning Insert CCGT09T304-FN2 WNN10

Product Description

The WALTER 6955645 is a CCGT-style carbide turning insert with ISO designation CCGT09T304-FN2 WNN10, engineered primarily for non-ferrous metal machining. It features a TiAlN PVD coating applied through a physical vapor deposition process and carries the FN2 chip breaker geometry. The insert has an 80-degree diamond shape, a positive rake angle of 18 degrees, and a honed cutting edge for clean, controlled cuts. With a 0.4 mm corner radius and a maximum depth of cut of 9.67 mm, it is suited for finishing and light-to-medium turning operations. Licensed CNC machinists and toolroom professionals install and index this insert in compatible CCGT-style toolholders.

This insert is designed for turning, facing, and boring operations. Its primary workpiece material is non-ferrous metal, making it a strong choice for aluminum, copper, and similar alloys. It also carries secondary ratings for steel and stainless steel applications under material grades P01 and M01. The neutral hand orientation makes it adaptable across a range of setups. The screw-type insert holding method is standard for CCGT-style toolholders commonly used in CNC turning centers and manual lathes.

Key Features

• TiAlN PVD coating optimized for non-ferrous metal cutting performance
• FN2 chip breaker geometry for controlled chip evacuation in finishing cuts
• 80-degree diamond insert shape with positive 18-degree rake angle
• Honed cutting edge style for reduced built-up edge on aluminum and non-ferrous alloys
• 2 cutting edges per insert; neutral hand for versatile toolholder compatibility
• Screw-type holding method for secure, repeatable indexing

Compatibility

Designed for use in CCGT-style screw-on toolholders conforming to ANSI and ISO standards. Compatible with turning, facing, and boring applications on non-ferrous metals as primary workpiece material, with secondary compatibility for steel and stainless steel per ISO material grades N10, P01, and M01.

Installation Notes

Indexing and installation should be performed by a qualified machinist with the machine powered off and the spindle fully stopped. Use the correct torque driver for the CCGT screw-type clamping system to avoid seat damage or insert fracture. Inspect the insert pocket and seating surface for chips or debris before indexing a new cutting edge. Follow the toolholder manufacturer guidelines and applicable shop safety protocols when handling carbide inserts, as edges are sharp and the substrate is brittle.
