Value Collection 383-4002 Threading Tool Bit E-4 C2 Carbide

Product Description

The VALUE COLLECTION 383-4002 is a single-point threading tool bit designed for precision cutting operations on lathes and similar turning equipment. Built to the E-4 industry standard, this bit features a C2-grade solid carbide tip and a neutral cutting direction, making it suitable for straight-in threading, chamfering, undercutting, and V-grooving operations. 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 on the tip conforms to standard thread-form geometry. Machinists and tool-and-die technicians typically use this style of bit in production and maintenance shop environments.

This tool bit is intended for threading and profile-cutting applications where a neutral rake geometry is required. Common uses include external and internal thread cutting, chamfer preparation, undercut relief work, and V-groove profiling on metal workpieces. The E-style shank format fits standard toolholders rated for 1/4-inch shank inserts. It is appropriate for use in job shops, maintenance facilities, and light manufacturing operations.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the tool bit from the holder. Secure the shank fully in the toolholder before resuming operation. Do not exceed the feed rates, speeds, or depth-of-cut limits specified for C2-grade carbide in the material being machined.
