Vargus 50355 Carbide Thread Mill Insert 9-12 Tpi

Product Description

The VARGUS 50355 is a carbide thread mill insert designed for internal threading operations using a partial profile 60-degree thread form. Manufactured from micrograin carbide with a PVD-applied TiCN coating, this insert delivers wear resistance and thermal stability in demanding milling applications. It covers a pitch range of 2.00 to 2.50 mm (9 to 12 TPI), making it suitable for cutting a span of common thread sizes in a single insert geometry. The insert style is 2UI with an inscribed circle of 6.35 mm. It is installed by toolroom machinists and CNC operators working in precision thread milling setups.

This insert is intended for internal thread milling on superalloy and titanium workpieces, identified by workpiece material code N. Its micrograin carbide substrate and TiCN coating are well-matched to the high-temperature and abrasive conditions common when machining these materials. Typical applications include threading bores in aerospace components, high-strength fastener housings, and other precision parts where a partial profile 60-degree thread form is required. The 2.00 to 2.50 mm pitch range covers metric thread sizes commonly encountered in these industries.

Key Features

• Micrograin carbide substrate provides fine grain structure for edge strength and wear resistance
• PVD TiCN coating reduces friction and extends tool life in superalloy and titanium cuts
• Partial profile 60-degree thread form mills internal threads across a pitch range without changing inserts
• Covers 2.00 to 2.50 mm pitch (9 to 12 TPI) for multi-size threading flexibility
• 6.35 mm inscribed circle fits standard 2UI insert seats on compatible thread mill bodies
• Manufacturer grade VBX optimized for difficult-to-machine N-group workpiece materials

Compatibility

Designed for use in thread mill bodies that accept the 2UI insert style with a 6.35 mm inscribed circle. Suited for internal partial profile 60-degree thread milling on superalloy and titanium workpieces.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolsetter. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torque driver and insert screw specified by the thread mill body manufacturer - do not overtighten, as carbide inserts are brittle and susceptible to fracture under excessive clamping load. Inspect the insert pocket for chips or damage before seating a new insert.
