Emuge GF643207.9517 Carbide Thread Mill Insert

Product Description

The EMUGE GF643207.9517 is a carbide thread mill insert designed for internal threading operations on CNC machining centers and milling machines. Finished with a TiAlN-T4 PVD coating, this insert is engineered to handle a pitch range of 2.5 to 5.5mm (approximately 4.5 to 10 TPI) and covers thread sizes from 4.2mm to 10mm in diameter. The GIGANT-IC insert style provides a rigid, high-contact seating geometry suited for demanding thread milling applications. This insert is a direct-fit replacement component for compatible EMUGE thread mill bodies and is installed by machinists and tool-crib technicians in precision machining environments.

This insert is intended for internal UN and ISO thread milling in materials classified under workpiece material codes K, M, N, P, and S - covering cast iron, stainless steel, non-ferrous alloys, steel, and heat-resistant superalloys. It is commonly used in job shop, aerospace, and general manufacturing environments where a single thread mill body handles multiple pitch ranges by swapping inserts. The non-conical geometry suits straight-thread applications rather than tapered thread forms.

Key Features

• TiAlN-T4 PVD coating for extended tool life in abrasive and hard-to-machine materials
• GIGANT-IC insert style with precision seating for repeatable thread accuracy
• Covers 2.5 to 5.5mm pitch range (4.5 to 10 TPI) in a single insert
• Compatible with UN and ISO internal thread forms
• Manufacturer Grade G629 carbide substrate for high wear resistance
• Non-conical geometry for straight internal thread milling

Compatibility

Designed for use with EMUGE GIGANT-IC thread mill bodies accepting this insert style. Suitable for machining workpiece material codes K, M, N, P, and S per the EMUGE material classification system.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or tooling technician. Always power down and lock out the spindle before handling inserts. Use the manufacturer-specified torque tool and clamping screw for the GIGANT-IC interface to ensure proper seating. Inspect the insert pocket and clamping screw for wear or debris before installing a new insert.
