Kennametal 5665949 Milling Insert GH1 Solid Carbide

Product Description

The KENNAMETAL 5665949 is a solid carbide milling insert in a parallelogram shape, designed for high-performance material removal in milling operations. Manufactured to the GH1 grade using a micrograin carbide substrate, this insert features a bright, uncoated finish and a positive rake geometry that reduces cutting forces and promotes clean chip evacuation. With 2 cutting edges, a 15-degree relief angle, and a sharp cutting edge style, it is built for precision milling of cast iron and non-ferrous metals. The insert is held in place via a screw-lock method and is designed for right-hand operation. Licensed HVAC techs, machinists, and tooling professionals specify this type of insert for demanding face and shoulder milling applications.

This insert is suited for use in face milling, shoulder milling, and general-purpose milling of cast iron and non-ferrous metal workpieces in both production and job-shop environments. It conforms to ANSI and ISO standards under the code ZDET16M508FR721 and is compatible with the 5720VZD16 cutter series. The 721 chip breaker geometry supports controlled chip formation across a range of feed rates and depths of cut typical in industrial milling setups.

Key Features

• Solid micrograin carbide construction for wear resistance and edge stability
• GH1 manufacturer grade with bright, uncoated finish — no coating delamination risk
• Positive rake geometry reduces cutting forces on cast iron and non-ferrous workpieces
• 15-degree relief angle with sharp cutting edge style for clean, precise cuts
• 2 cutting edges per insert for extended tool life per piece
• Screw-lock holding method provides secure, repeatable seating in compatible cutter bodies

Compatibility

Compatible with the 5720VZD16 cutter series. ANSI and ISO insert code ZDET16M508FR721. Designed as an OEM-style replacement insert for ZDET-series milling cutter bodies accepting size 16 parallelogram inserts.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the cutter body manufacturer's torque and seating procedures. Power down and lock out the machine spindle before replacing any insert. Inspect the cutter body pocket and clamping screw for damage or contamination before seating the new insert. Use the correct Torx or hex key specified by the cutter body manufacturer — do not substitute driver sizes.
