Walter 6955642 Turning Insert CCGT060204-FN2 WNN10

Product Description

The WALTER 6955642 is a CCGT-style carbide turning insert in the CCGT-FN2 series, designed for precision machining of non-ferrous metals. It carries a TiAlN coating applied via PVD process, providing wear resistance and thermal stability during high-speed cuts. The insert features an 80-degree diamond shape, a positive rake angle of 18 degrees, a 7-degree relief angle, and a honed cutting edge. With a 0.4 mm corner radius and a maximum depth of cut of 6.45 mm, it is suited for finishing and semi-finishing operations. Licensed machinists and CNC programmers working in job shops or production environments are the primary users of this insert.

This insert is engineered primarily for turning, facing, and boring of non-ferrous metals such as aluminum and copper alloys. It is also rated for secondary use on steel and stainless steel workpiece materials. The FN2 chip breaker geometry supports smooth chip evacuation during light to medium cuts. It is compatible with screw-clamping toolholders designed to accept CCGT-style inserts and fits standard indexable turning systems used on CNC lathes and machining centers.

Key Features

• TiAlN PVD coating for extended tool life on non-ferrous and steel applications
• 80-degree diamond insert shape with positive 18-degree rake angle for reduced cutting forces
• FN2 chip breaker geometry optimized for non-ferrous turning, facing, and boring
• Honed cutting edge for consistent surface finish on finishing passes
• 2 usable cutting edges per insert
• Screw-clamping retention method for secure, repeatable indexing

Compatibility

Designed for use in screw-clamping indexable toolholders that accept CCGT-style inserts. Suitable for CNC lathes and turning centers performing turning, facing, and boring operations on non-ferrous metals, steel, and stainless steel workpieces.

Installation Notes

Indexable insert installation and indexing should be performed by a qualified machinist with the machine in a full stop and lockout-tagout procedures followed. Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer specification. Inspect the toolholder seat and clamp for debris or damage before seating a new insert. Do not exceed the maximum depth of cut rating for the insert size.
