Accupro 130-MG Single Point Tool Bit Lh Square Shoulder

Product Description

The ACCUPRO 130-MG is a left-hand, single point tool bit designed for square shoulder turning operations on aluminum and similar non-ferrous materials. The cutting tip is micrograin solid carbide, ground to a 1/32 inch nose radius for clean, precise finishes. The shank measures 3/4 inch wide by 3/4 inch high, with an overall length of 4-1/2 inches. This tool bit is intended for use in production and job-shop turning applications where consistent chip geometry and edge retention matter. It is installed by machinists and tool-and-die professionals working on CNC or manual lathes and boring setups.

The 130-MG is suited for boring, chamfering, and turning operations, particularly in applications requiring a left-hand cutting direction. The AL tool bit style and square shoulder profile make it a practical choice for facing passes and shoulder work on aluminum workpieces. The micrograin carbide grade provides a fine grain structure that supports sharper cutting edges and improved surface finish over standard carbide grades. The industry standard designation for this tool is AL-12.

Key Features

• Micrograin solid carbide tip for superior edge retention and finish quality
• Left-hand cutting direction for specific lathe setups requiring reverse-feed tooling
• Square shoulder turning geometry suitable for boring, chamfering, and straight turning
• 3/4 inch by 3/4 inch shank for rigid tool holding in standard tool posts and blocks
• 1/32 inch nose radius for precise corner geometry on finished cuts
• 4-1/2 inch overall length providing adequate reach for most standard turning applications

Compatibility

Designed as an OEM-style single point tool bit for use in standard tool holders accepting a 3/4 inch square shank, compatible with manual and CNC lathes configured for left-hand cutting operations on aluminum and similar materials.

Installation Notes

This tool bit is installed by qualified machinists following standard lathe setup procedures. Ensure the machine is powered down and spindle rotation is locked before seating or adjusting the tool bit in the holder. Set tool height on center using a reference gauge before beginning a cut. Secure the shank firmly in the tool post or block to prevent chatter and protect the carbide tip from impact damage.
