Emuge GF643205.9517 Carbide Thread Mill Insert Tin

Product Description

The EMUGE GF643205.9517 is a carbide thread mill insert designed for internal thread milling operations across UN and ISO thread standards. Manufactured to EMUGE grade G621, this insert carries a Titanium Nitride (TiN) coating that improves surface hardness and extends tool life in demanding cutting applications. It covers a pitch range of 2.5 to 5.5mm (10 to 4.5 TPI) and features an 8.50mm width, making it a versatile option for shops running a range of thread sizes on a single holder. The GIGANT-IC insert style is a recognized EMUGE system format. Installation is performed by machinists and toolroom technicians in CNC machining environments.

This insert is suited for internal thread milling on a broad range of workpiece materials. The universal primary workpiece material designation covers material codes K, M, N, P, and S, which correspond to cast iron, stainless steel, non-ferrous metals, steel, and heat-resistant superalloys respectively. Typical applications include production machining on CNC machining centers where a single insert must handle multiple thread pitches within the 2.5 to 5.5mm range. The non-conical geometry confirms a straight-profile insert seat.

Key Features

• Carbide substrate at EMUGE grade G621 for wear resistance in universal workpiece materials
• Titanium Nitride (TiN) coating improves surface hardness and reduces built-up edge
• Covers 2.5 to 5.5mm pitch range (10 to 4.5 TPI) for multi-pitch thread milling with one insert
• Compatible with UN and ISO internal thread standards
• GIGANT-IC insert style for use with corresponding EMUGE thread mill bodies
• Non-conical geometry with 8.50mm width for consistent seating and repeatability

Compatibility

Designed for use with EMUGE GIGANT-IC series thread mill bodies that accept the GF643205.9517 insert format. Confirm holder compatibility with EMUGE tooling documentation before ordering.

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine spindle fully stopped and the CNC program placed in a safe hold state. Use the correct EMUGE torque key or insert screw driver specified for the GIGANT-IC holder to seat the insert properly - do not use improvised tools that may damage the seating pocket. Inspect the insert pocket for chips or contamination before installing the new insert. Follow your facility safety procedures and machine manufacturer guidelines for tooling changes.
