Accupro ACC-LC312080 Cut-off Grooving Tool Bit 5/16 in Lh

Product Description

The ACCUPRO ACC-LC312080 is a single point tool bit designed for cut-off and grooving operations on manual and CNC lathes. Manufactured to LC style geometry with a solid carbide tip, it delivers consistent edge retention and dimensional accuracy in ferrous and non-ferrous turning applications. The shank measures 5/16 inches in both width and height, and the tool has an overall length of 6 inches. The tip width and thickness each measure 0.080 inches, making it suited for narrow grooving and part-off work where precise slot width control is required. This tool is installed by machinists and toolroom technicians working in production or job-shop environments.

The ACC-LC312080 is configured for left-hand cutting direction, following LC style toolholder geometry. It is used in applications requiring cut-off or grooving on a lathe, typically in light-to-medium duty turning setups. The solid carbide tip provides performance in both continuous and interrupted cut scenarios where high-speed steel alternatives would wear prematurely. It is packaged individually and ordered in single-unit quantities, making it practical for targeted tool replacement or low-volume toolroom stocking.

Key Features

• LC style single point geometry for cut-off and grooving operations
• Solid carbide tip for extended edge life versus high-speed steel alternatives
• Left-hand cutting direction for correct chip flow in standard LC toolholder setups
• Tip width and thickness of 0.080 inches for narrow-slot grooving and part-off work
• 5/16 inch square shank fits standard LC-style toolholders
• 6-inch overall length provides toolholder clearance in typical lathe setups

Compatibility

Designed as a direct-fit replacement for LC style single point toolholders requiring a 5/16 inch square shank, left-hand cut-off and grooving tool bit. Industry standard number LC-312080 applies.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The machine spindle must be fully stopped and the lathe powered down before changing or seating tool bits. Ensure the tool bit is seated squarely in the toolholder and clamping screws are tightened evenly to prevent tip chipping during initial cuts. Inspect the carbide tip for cracks or edge damage before use, as a compromised carbide edge can fracture under cutting load.
