Vargus 53652 Threading Insert 32 Tpi Unj Solid Carbide

Product Description

The VARGUS 53652 is a solid carbide laydown threading insert designed for external UNJ thread forms at 32 threads per inch. It features a 60-degree included angle and carries a TiAlN coating applied by PVD process, using the VTX micrograin carbide grade. The insert measures 9.53 mm inscribed circle (0.375 inches) with a thickness of 3.60 mm and is configured for right-hand cutting. It is engineered for use on CNC lathes and turning centers where controlled thread geometry and consistent surface finish are required by machinists and tooling specialists.

This insert is suited for producing external UNJ threads to MIL-S-8879C standards, a thread form commonly specified in aerospace and defense applications. The UNJ profile incorporates a controlled root radius that improves fatigue resistance in threaded fasteners. The universal primary workpiece material designation makes it applicable across a broad range of materials, including carbon steels, stainless steels, cast irons, non-ferrous alloys, high-temperature alloys, and titanium alloys. It is intended for use by machinists and CNC programmers working to aerospace or military thread specifications.

Compatibility

Designed as an OEM-style replacement threading insert in the 3ER insert style, size code 3, for use in compatible laydown threading toolholders accepting this insert geometry.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or replacing the insert. Use the appropriate torx or clamping key specified by the toolholder manufacturer to achieve correct clamping force without over-torquing. Verify thread form and pitch against part drawing requirements before beginning production cuts.
