Vargus 51175 Threading Insert 11 Tpi Un Solid Carbide

Product Description

The VARGUS 51175 is a laydown-style solid carbide threading insert designed for external UN thread forms at 11 threads per inch. Manufactured in the 3ER insert style with a 3/8 inch inscribed circle and a thickness of 3.60 mm (approximately 0.142 inches), this insert carries a TiAlN coating applied via PVD process. The 60-degree included angle and single-tooth profile make it well suited for producing precise UN thread forms on a lathe. It is intended for use by machinists and CNC turning specialists working with a broad range of workpiece materials, including steel, stainless, aluminum, cast iron, high-temp alloys, and non-ferrous metals.

The 51175 is used in CNC turning and manual lathe operations where right-hand external UN threads at 11 TPI are required. Its universal material compatibility covers a wide range of workpiece grades, making it a practical single-insert solution across job shop and production environments. The insert seats in standard 3ER-style toolholders. It is sold individually but carries a minimum order quantity of 10 units, making it suitable for stocking as a production consumable rather than a one-off replacement.

Designed for use in standard 3ER-style external threading toolholders. Intended for right-hand external UN thread applications at 11 TPI on CNC and manual turning equipment.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque and clamping specifications. Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before changing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Follow your facility's lockout/tagout procedure before performing any tooling changes on CNC or manual lathes.
