Kennametal 5666376 Milling Insert GH1 Solid Carbide Zdet

Product Description

The KENNAMETAL 5666376 is a solid carbide milling insert in a parallelogram shape designed for precision metal removal in milling applications. Built to ANSI and ISO standards under style designation ZDET, this insert features a bright uncoated micrograin carbide construction and a positive rake geometry with a sharp cutting edge style. With a 15-degree relief angle and a corner radius of 0.066 inches, it delivers clean, controlled cuts. The insert is held in place by screw clamping and is suited for use by machinists and tooling technicians working with indexable milling cutter bodies.

This insert is intended for right-hand milling operations targeting cast iron and non-ferrous metal workpieces. It fits the KENNAMETAL 5720VZD16 cutter series and carries the ANSI and ISO code ZDET16M516FR721. The 721 chip breaker geometry supports chip control in these material categories. It is a single-sided insert with two cutting edges, making it a practical indexable option for production and maintenance machining environments. The insert size code is 16M516.

Key Features

• Solid carbide micrograin construction in manufacturer grade GH1 for wear resistance in cast iron and non-ferrous applications
• Positive rake geometry with sharp cutting edge style for reduced cutting forces
• 15-degree relief angle and 0.066-inch corner radius for precise edge engagement
• Two cutting edges per insert with right-hand orientation for extended tool life per insert
• Bright uncoated finish suitable for non-ferrous metals where coatings may cause adhesion issues
• Screw-held mounting compatible with KENNAMETAL 5720VZD16 cutter series

Compatibility

Designed for use with the KENNAMETAL 5720VZD16 cutter series. ANSI and ISO designation ZDET16M516FR721 confirms fitment. Primary workpiece materials are cast iron and non-ferrous metal.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key as specified by the cutter body manufacturer to seat the clamping screw. Inspect the cutter pocket and seating surface for damage or debris before installing a new insert.
