Value Collection 47112 Ar Square Shoulder Turning Tool Bit

Product Description

The VALUE COLLECTION 47112 is a solid carbide single-point tool bit ground to the AR style for square shoulder turning operations on the lathe. It features a 1 x 1 inch square shank cross-section and a 7 inch overall length, making it a standard-size insert-free brazed bit suited for shops running conventional toolholders. The tip material is solid carbide grade K21, which provides the hardness and wear resistance needed for ferrous and non-ferrous interrupted cuts. A 1/32 inch nose radius balances surface finish quality with edge strength. Right-hand cutting orientation is built into the geometry.

This tool bit is used in turning and boring operations on manual and CNC lathes where a brazed solid carbide AR-style bit is required. Typical applications include square shoulder turning, chamfering, and general-purpose boring in a production or job-shop environment. Machinists and tool-and-die technicians working with steel, cast iron, and non-ferrous alloys will find the K21 carbide grade appropriate for moderate to high cutting speeds at standard depth-of-cut ranges.

Key Features

• Solid carbide tip, grade K21 for wear resistance in turning and boring
• AR tool bit style with right-hand cutting direction
• 1 x 1 inch square shank cross-section fits standard AR toolholders
• 7 inch overall length meets common lathe tool post requirements
• 1/32 inch nose radius suitable for general-purpose finish and roughing passes
• Rated for boring, chamfering, and square shoulder turning applications

Compatibility

Designed as a direct-fit replacement or working spare for standard AR-style toolholders accepting a 1 x 1 inch shank. Industry Standard Number AR-16 applies to this geometry.

Installation Notes

Installation is performed by a machinist or toolroom technician. The tool bit must be clamped securely in a matched AR-style toolholder with set screws torqued according to the toolholder manufacturer's specification. Confirm shank seating and center height before taking a cut. Inspect the carbide tip for chipping or cratering before each use and replace the bit if the cutting edge shows visible wear or damage.
