The VALUE COLLECTION 383-8506 is a square shank boring tool bit conforming to the TSC-5 industry standard. It features a solid carbide tip graded C6, suited for general-purpose boring operations in metal cutting applications. The shank measures 5/16 inches in both height and width, and the overall length is 1.5 inches. A neutral cutting direction makes this bit appropriate for straight boring passes without a left or right hand orientation preference. Machinists and tool and die professionals install this type of bit in boring bars and related holders for internal diameter work on lathes and machining centers.
This tool bit is designed for boring applications in machining environments, including job shops and production floors. The TSC-5 standard geometry ensures compatibility with holders and boring bars built to that specification. The 1/64 inch nose radius provides a controlled surface finish during boring passes. The compact 1.5 inch overall length suits smaller boring bar setups where clearance is limited.
Designed as an OEM-style replacement or direct-fit tool bit for boring bars and holders built to the TSC-5 industry standard with a 5/16 inch square shank bore.
Installation is performed by machinists using appropriate boring bar holders that accept a 5/16 inch square shank. Secure the tool bit with the set screw torqued to the holder specification before engaging the workpiece. Ensure the machine spindle is fully stopped and the machine is in a locked-out state before installing or removing the bit. Follow your facility's tooling and machine guarding procedures throughout setup.
