Walter 7469770 Milling Insert SDHT1204AZN-G88 WXN15 Carbide

Product Description

The WALTER 7469770 is a solid carbide milling insert carrying ANSI and ISO designation SDHT1204AZN-G88 in manufacturer grade WXN15. It is a square-style, single-sided insert designed for use in milling cutters in the M4000 series. The insert features a TiCN coating applied via PVD process, a positive rake angle of 20 degrees, and a sharp cutting edge style. With four usable cutting edges and a neutral hand orientation, it is suited for high-efficiency milling of non-ferrous metals. Licensed machinists and CNC tooling technicians are the primary installers and users of this insert.

This insert is engineered specifically for primary workpiece material code N, covering non-ferrous metals such as aluminum alloys, copper, and similar materials. It fits into the WALTER M4000 cutter series and is identified by insert size code 1204, with a 0.5000 inch inscribed circle and a 3/16 inch thickness. The G88 chip breaker geometry supports controlled chip formation during milling operations. It is appropriate for both horizontal and vertical milling machine setups in production and job-shop environments.

Key Features

• Solid carbide substrate with PVD-applied TiCN coating for extended tool life on non-ferrous materials
• Square insert shape (SDHT style) with 90-degree included angle and positive 20-degree rake for reduced cutting forces
• Four cutting edges per insert, neutral hand orientation for flexible cutter loading
• G88 chip breaker designed for controlled chip evacuation in non-ferrous milling
• Maximum depth of cut of 0.5000 inch (0.5000 decimal inch)
• Corner radius of 0.0120 inch and 15-degree relief angle for sharp, precise edge engagement

Compatibility

Compatible with WALTER M4000 series milling cutters. Insert is held by screw-clamp method. ANSI and ISO code SDHT1204AZN-G88 WXN15 applies for cross-referencing to equivalent cutter bodies accepting the SDHT 1204 insert form factor.

Installation Notes

Installation is performed by CNC machinists or tooling technicians during cutter body setup or insert indexing. Always power down and lock out the machine spindle before seating or indexing inserts. Use the correct torx or hex key specified by the cutter body manufacturer when tightening the clamping screw - do not overtighten. Inspect the insert pocket seating surface and clamp for debris or wear before loading a new insert.
