Vargus 50018 Carbide Thread Mill Insert 16-12 Tpi

Product Description

The VARGUS 50018 is a carbide thread mill insert engineered for internal threading operations requiring a partial profile 60-degree thread form. Designed with a TiCN finish applied via PVD coating, this insert carries a micrograin carbide substrate under the VBX manufacturer grade designation. It covers a pitch range of 1.5 to 2.0 mm, equivalent to 16 to 12 TPI, making it well-suited for moderate-pitch internal thread milling in a single tool path. The insert style is 2UI with an inscribed circle of 6.35 mm. Machinists and tooling specialists working in CNC milling environments install this insert into compatible thread mill bodies for precision thread generation.

This insert is intended for thread milling applications involving non-ferrous metals, superalloys, and titanium workpieces, corresponding to workpiece material code N. It is used in CNC machining centers performing internal thread milling where a partial profile 60-degree standard is required. The 1.5 to 2.0 mm pitch range suits a broad range of fastener thread sizes commonly encountered in aerospace, medical, and precision manufacturing work. The VBX grade with TiCN PVD coating provides wear resistance appropriate for the listed workpiece materials.

Key Features

• Partial profile 60-degree thread standard covers a wide range of metric and unified internal thread forms
• Pitch range of 1.5 to 2.0 mm (16 to 12 TPI) in a single insert reduces tooling changeovers
• 2UI insert style with 6.35 mm inscribed circle for use in compatible VARGUS thread mill bodies
• VBX manufacturer grade optimized for non-ferrous metals, superalloys, and titanium

Compatibility

Designed for use with compatible VARGUS 2UI-style thread mill bodies accepting a size-2 insert with a 6.35 mm inscribed circle. No additional specific compatible model numbers were provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with CNC thread milling operations. Ensure the machine spindle is fully stopped and the tool is secured in the holder before seating or removing the insert. Follow the tool body manufacturer torque guidelines for clamping screws and inspect seating surfaces for debris before installation. Refer to applicable shop safety procedures and machine tool documentation when handling carbide inserts, as edges are sharp.
