Vargus 50034 Carbide Thread Mill Insert 60 Degree 16-12 Tpi

Product Description

The VARGUS 50034 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 TiAlN coating, it delivers consistent performance on steel workpieces where tool life and edge integrity are critical. The insert covers a pitch range of 1.5 to 2.0 mm and a teeth-per-inch range of 16 to 12 TPI, making it a versatile option across common thread sizes. It is intended for use in CNC thread milling applications where a single insert style handles multiple pitches within its range.

This insert is suited for internal thread milling in ferrous materials, primarily steel (ISO material group P). It fits standard thread mill bodies that accept the 3UI insert style with a 3-size code and a 9.53 mm inscribed circle. Shops running production thread milling on CNC machining centers will find it appropriate for a range of metric and unified thread callouts within the 1.5-2.0 mm pitch and 16-12 TPI window. It is sold individually per package, with a minimum order quantity of 10 pieces.

Key Features

• Micrograin carbide substrate for improved edge strength and wear resistance
• TiAlN coating applied via PVD process for thermal resistance during dry or semi-dry cutting
• Partial profile 60-degree thread form covers both metric and unified thread standards within pitch range
• Pitch range of 1.5 to 2.0 mm with corresponding 16-12 TPI coverage
• 9.53 mm inscribed circle matches standard 3UI insert body seats
• Optimized for steel workpieces in internal threading applications

Compatibility

Designed for use in thread mill bodies that accept the 3UI insert style, size code 3, with a 9.53 mm inscribed circle. Compatible with internal partial profile 60-degree thread milling operations on steel and similar ferrous materials within the 1.5 to 2.0 mm pitch or 16 to 12 TPI range.

Installation Notes

Installation of thread mill inserts should be performed by a qualified machinist or toolroom technician. Ensure the thread mill body is fully de-energized and removed from the machine spindle before seating or replacing inserts. Use the manufacturer-specified torx or hex key for insert clamping screws and avoid over-torquing the clamping mechanism. Verify insert seating and tool runout before returning the assembly to service.
