The VALUE COLLECTION 383-0126 is a single-point tool bit designed for precision metal-cutting operations on lathes and boring setups. Manufactured to AL-5 industry standard dimensions, this square shoulder turning bit features a C6-grade solid carbide tip brazed to a square shank measuring 5/16 inches in height and 5/16 inches in width. The overall length is 2.25 inches. The left-hand cutting direction makes it suited for climb-cutting operations and specific turning orientations where a conventional right-hand bit cannot engage the workpiece correctly. Machinists and tool-and-die technicians are the primary installers of this style of bit.
This tool bit is used in manual and CNC lathe operations for boring, chamfering, and turning applications. It is appropriate for light to medium stock removal on a range of metals. The AL-5 style designation places it within a standardized form factor, making it a straightforward drop-in for toolholders designed to accept 5/16-inch square shank inserts. It is well-suited for job shops, maintenance machining, and production environments where consistent geometry and tip hardness are required.
Designed as an OEM-style replacement or direct-fit option for toolholders accepting 5/16-inch square shank, AL-style single-point tool bits in left-hand cutting configurations.
This tool bit is installed by machinists using standard lathe toolholders rated for 5/16-inch square shanks. Ensure the lathe spindle is fully stopped and the machine is powered down before seating or removing the tool bit. Confirm proper overhang and tool height alignment relative to workpiece centerline before taking a cut. Follow applicable shop safety procedures and machine manufacturer guidelines for tool clamping torque.
