Value Collection 383-6202 ER-4 Single-point Tool Bit

Product Description

The VALUE COLLECTION 383-6202 is a single-point threading tool bit designed for offset threading and V-grooving operations on metal lathes and turning centers. Built to ER-4 industry standards, it features a C2-grade solid carbide tip brazed to a steel shank, delivering the hardness and wear resistance required for threading steel, cast iron, and similar ferrous materials. The shank measures 1/4 inch in height and 1/4 inch in width, with an overall length of 2 inches. The 60-degree included angle matches standard unified and metric thread forms. Right-hand cutting direction means the tool advances from right to left along the workpiece.

This tool bit is suited for threading and V-grooving to shoulder on manual engine lathes and CNC turning centers in job shops, maintenance shops, and production environments. The compact 1/4-inch shank fits standard ER-style tool holders and small-bore turning setups. Machinists and tool and die makers working on threaded fasteners, fittings, and shouldered components are the primary users. The ER-4 designation matches a recognized industry standard, making sourcing and replacement straightforward.

Installation Notes

Installation is performed by machinists or toolroom technicians. Secure the tool bit firmly in the appropriate ER-4 tool holder and verify shank seating before operation. Confirm the lathe spindle is fully stopped and the machine is in a safe, locked-out state before changing or adjusting tool bits. Follow the machine manufacturer guidelines for tool protrusion and clamping torque as specified in the equipment manual.
