Value Collection 383-0142 AL-7 Left Hand Tool Bit C2 Carbide

Product Description

The VALUE COLLECTION 383-0142 is a single-point tool bit designed for precision metal cutting operations in machine shop and production environments. Built to the AL-7 industry standard, this left-hand, square shoulder turning bit features a C2 solid carbide tip brazed onto the shank. The 7/16-inch shank height and 7/16-inch shank width provide a rigid, square cross-section that seats securely in standard tool holders. At 3 inches overall length, it is sized for typical lathe and boring bar applications. Machinists and toolroom operators select this style of bit for reliable chip control and consistent edge geometry on ferrous and non-ferrous materials.

This tool bit is suited for boring, chamfering, and turning operations on manual and CNC lathes, turret lathes, and similar single-point turning setups. The left-hand cutting direction makes it the correct choice for right-to-left pass operations, undercutting, and back-facing work where a right-hand bit cannot reach. It is appropriate for light to medium cutting conditions typical of job shops, maintenance machine shops, and production turning cells.

Key Features

• AL-7 industry standard geometry for consistent interchangeability with compatible tool holders
• C2 solid carbide tip grade suited for general-purpose turning of cast iron, non-ferrous metals, and similar materials
• Left-hand cutting direction for right-to-left passes, undercutting, and back-facing operations
• Square shoulder turning style provides stable tool holder contact and predictable cutting geometry
• 3-inch overall length fits standard single-point tool posts and turret holders
• 7/16-inch square shank minimizes deflection during boring, chamfering, and turning cuts

Compatibility

Designed as an OEM-style replacement or direct-fit tool bit for machine tool holders accepting AL-7 style single-point bits with a 7/16-inch square shank.

Installation Notes

Installation is performed by qualified machinists. Secure the bit firmly in the tool holder or tool post, ensuring the shank is fully seated with no overhang beyond what the operation requires, to minimize chatter and deflection. Power down and lock out the machine before loading or adjusting the tool bit. Inspect the carbide tip for cracks or chipping before each use and replace any bit showing edge damage to prevent workpiece damage or tool failure.
