Value Collection 383-4006 Threading Tool Bit E-4 1/4 in

Product Description

The VALUE COLLECTION 383-4006 is a single-point threading tool bit designed for precision cutting operations on lathes and manual machining equipment. Built to Industry Standard E-4 with a style E profile, this tool bit features a solid carbide tip rated C6 for wear resistance in demanding applications. The neutral cutting direction allows straight-in engagement without left or right hand bias. At 2 inches overall length with a 1/4 inch square shank, it is sized for smaller toolholders and bench lathes. Machinists and tool and die professionals install this type of bit when thread-cutting, chamfering, undercutting, or V-grooving operations are required.

This tool bit is suited for threading and form-cutting work on manual lathes, CNC lathes, and turret setups where an E-style single-point bit is specified. The 60-degree included angle makes it appropriate for standard unified thread forms as well as V-groove and chamfer cuts. Typical applications include threading external and internal features, undercutting relief grooves, and cutting chamfers on turned components in job shop, production, and maintenance machining environments.

Key Features

• C6 solid carbide tip for hardness and wear resistance in threading applications

Compatibility

Designed as an OEM-style replacement or direct specification fit for toolholders and turret blocks accepting an E-4 style single-point tool bit with a 1/4 inch square shank.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the lathe or machining center before seating or adjusting the tool bit in the holder. Set tool height to centerline of the workpiece and confirm the tip is properly supported in the holder before resuming cuts. Carbide tips are brittle and should not be subjected to interrupted cuts or heavy feed rates beyond the tool geometry rating.
