Value Collection 383-8312 GL-10 Tool Bit Left Hand Carbide

Product Description

The VALUE COLLECTION 383-8312 is a single-point, offset end-cutting tool bit designed for lathe turning and facing operations. Built to the GL-10 industry standard, it features a C2-grade solid carbide tip brazed to a steel shank, providing the hardness and wear resistance needed for production turning on steel, cast iron, and similar materials. The shank measures 5/8 inches in height and 5/8 inches in width, with an overall length of 4 inches. A 1/32-inch nose radius gives the cutting edge a controlled, repeatable finish geometry suited for shoulder turning and work performed close to the chuck jaw.

This tool bit is configured for left-hand cutting direction, making it appropriate for right-to-left turning passes on a manual or CNC lathe. The GL-style offset end-cutting geometry is commonly used in turning and facing-to-shoulder applications, as well as operations that require the cutting tool to work in close proximity to the chuck jaw or a workpiece shoulder. It is typically installed by machinists and toolroom operators in job shop, maintenance machining, and light production environments.

Key Features

• GL-10 industry standard designation for consistent toolholder compatibility
• C2-grade solid carbide tip for wear resistance on steel and cast iron
• Offset end-cutting geometry for shoulder turning and chuck-clearance work
• Left-hand cutting direction for right-to-left lathe passes
• 1/32-inch nose radius for controlled surface finish
• Compact 4-inch overall length suited for standard tool post holders

Compatibility

Designed as an OEM-style replacement or direct-fit single-point tool bit for GL-10 standard toolholders used in manual and CNC lathe applications.

Installation Notes

Installation is performed by machinists using a standard tool post or boring bar holder sized for a 5/8-inch shank. Ensure the lathe is fully powered down and the spindle is locked before seating or adjusting the tool bit. Set tool height to centerline using shims or an adjustable holder before taking a cut. Do not exceed the cutting parameters appropriate for the workpiece material and C2 carbide grade.
