Accupro 31-MG Single Point Tool Bit Ar Square Shoulder

Product Description

The ACCUPRO 31-MG is a single point tool bit ground from micrograin solid carbide and configured in the AR style for right-hand square shoulder turning operations. The 3/4-inch square shank fits standard tool holders designed for that size class, and the 4.5-inch overall length provides the reach and rigidity needed for boring, chamfering, and turning applications. The 1/32-inch nose radius delivers a controlled surface finish on ferrous and non-ferrous workpieces. Industry standard number AR-12 makes cross-referencing with tooling catalogs straightforward. Machinists and toolroom operators working on manual or CNC lathes use this bit where consistent carbide performance and repeatable geometry are required.

This tool bit is suited for lathe work in job shop, production, and maintenance machining environments. Typical applications include external turning, shoulder facing, and light boring passes on a range of materials. The AR-style geometry is a widely recognized industry configuration, making it a direct fit wherever AR-12 standard tooling is specified. It is sold and packaged as a single unit, making it practical for both replacement of a worn bit and new tooling setups.

Compatibility

Designed as an OEM-style replacement or new-setup tool bit for lathes and turning centers that accept 3/4-inch square shank AR-style single point tooling per industry standard AR-12.

Installation Notes

This tool bit is installed and serviced by machinists and toolroom technicians. Secure the shank firmly in a qualified tool holder or boring bar before engaging the spindle, and verify that shank seating and overhang comply with the machine tool manufacturer's guidelines. Always stop the spindle and confirm the machine is in a safe, de-energized state before changing or adjusting any cutting tool. Follow applicable shop safety standards and machine-specific operating procedures when setting tool height and cutting parameters.
