Value Collection 383-6206 ER-4 Single-point Tool Bit

Product Description

The VALUE COLLECTION 383-6206 is an ER-4 style single-point tool bit designed for offset threading and V-grooving applications on metal lathes and threading equipment. The bit features a solid carbide tip rated at C6 grade, providing the hardness and wear resistance required for threading steel, cast iron, and similar ferrous materials. With a 60-degree included angle, it cuts standard thread forms and V-grooves cleanly. The shank measures 0.25 inches in height and 0.25 inches in width, with an overall length of 2 inches. Right-hand cutting direction. Machinists and toolroom operators working with manual or CNC lathes will find this bit suited to threading and shoulder-approach grooves where tool clearance is a priority.

This tool bit is intended for use in threading and V-grooving operations, particularly where threading to a shoulder is required. The ER-4 style offset geometry allows the cutting edge to approach workpiece shoulders more closely than a straight tool bit, reducing the relief needed between threads and a mating face. Typical applications include threading on small-diameter stock, production lathe work, and toolroom turning operations. The compact 0.25-inch shank fits standard tool holders and lantern-style toolposts configured for quarter-inch shank tooling.

Compatibility

Designed as an OEM-style replacement or standard toolroom insert for tool holders and toolposts accepting a 0.25-inch square shank single-point tool bit.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the tool bit in a compatible tool holder, ensuring the shank is fully seated and clamping screws are tightened to the tool holder specification. Power down and lock out the lathe spindle before mounting or adjusting the bit. Handle solid carbide tooling carefully to avoid chipping the cutting edge against hard surfaces.
