Accupro 36-MG AR-16 Single-point Tool Bit Solid Carbide

Product Description

The ACCUPRO 36-MG is a single-point tool bit designed for square shoulder turning operations on metal lathes and boring machines. Built to AR-16 industry standards, it features a micrograin solid carbide tip brazed to a rigid steel shank measuring 1 inch in height and 1 inch in width, with an overall length of 7 inches. The right-hand cutting direction and 1/32-inch nose radius make it well suited for finish turning, chamfering, and boring passes where tight tolerances and clean surface finishes are required. At 1.6 pounds, the shank provides enough mass to resist chatter during aggressive material removal.

This tool bit is used in manual and CNC turning applications across job shops, production machining, and toolroom environments. Typical operations include external diameter turning, chamfering, and light to moderate boring on ferrous and non-ferrous metals. The micrograin carbide grade offers a good balance of hardness and toughness, making it appropriate for interrupted cuts and materials that cause rapid edge wear on standard carbide grades. It is typically installed by machinists and tool-and-die professionals in lathe tool posts or boring bar holders.

Key Features

• AR-16 industry standard tool bit for broad holder compatibility
• Micrograin solid carbide tip for improved wear resistance and edge retention
• Right-hand cutting direction for standard lathe setups
• 1/32-inch nose radius suited for finish and semi-finish turning passes
• Rated for boring, chamfering, and turning applications
• 7-inch overall length with 1-inch square shank for rigid tool post mounting

Compatibility

Designed as an AR-16 standard single-point tool bit compatible with tool posts and holders that accept 1-inch square shank, right-hand turning inserts in AR-style configurations.

Installation Notes

Installation is performed by machinists using standard lathe tool posts or turrets rated for 1-inch square shank tooling. Power down and lock out the lathe spindle before seating or adjusting the tool bit in the holder. Ensure the cutting edge is set on center with the workpiece axis before engaging the cut. Inspect the carbide tip for chipping or cratering before each use, as damaged edges can cause workpiece damage and unexpected tool failure.
