Accupro ACC-LC312040 Cut-off Tool Bit Left Hand

Product Description

The ACCUPRO ACC-LC312040 is a single-point LC-style tool bit designed for cut-off and grooving operations on metal lathes and turning centers. The bit features a solid carbide tip with a 0.040-inch tip thickness and 0.040-inch tip width, suited for narrow-groove and parting work requiring precise dimensional control. The shank measures 5/16 inch in height and 5/16 inch in width, with an overall length of 6 inches. The left-hand cutting direction suits specific toolpost orientations and lathe configurations. Machinists and toolroom operators working in production and job-shop environments are the primary users of this tool bit.

This tool bit is intended for cut-off and grooving applications in metal turning operations. Its LC-style geometry and solid carbide tip make it a practical choice for parting stock and cutting narrow grooves in ferrous and non-ferrous materials. The left-hand cutting direction accommodates setups where the tool engages the workpiece from the opposite side of a standard right-hand configuration. Typical installations are found in manual lathes and CNC turning centers in both production and maintenance machining environments.

Key Features

• Solid carbide tip for extended wear resistance in cut-off and grooving applications
• LC-style single-point geometry optimized for parting and narrow-groove operations
• Left-hand cutting direction for specific toolpost and lathe orientations
• Tip thickness and tip width both at 0.040 inches for precise, consistent groove sizing
• 5/16 inch square shank cross-section for standard toolholder fitment
• 6-inch overall length provides reach and rigidity in typical lathe setups

Compatibility

Designed as an OEM-style replacement and standard toolroom cutting tool for LC-style single-point tool bit holders accepting a 5/16 inch square shank.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. The tool bit should be secured firmly in a compatible toolholder or toolpost, ensuring the shank seats fully and the cutting edge is set at the correct center height for the workpiece. The machine spindle must be brought to a full stop and the lathe powered down before changing or adjusting tool bits. Do not exceed the toolholder manufacturer's recommended depth-of-cut or feed rate for carbide-tipped cut-off tools.
