Value Collection 383-4046 Threading Tool Bit E-8 C6 Carbide

Product Description

The VALUE COLLECTION 383-4046 is a single-point threading tool bit designed for precision metal cutting operations on lathes and turning centers. Built to industry standard E-8 specifications, it features a solid carbide tip rated C6 grade, delivering the hardness and wear resistance required for threading, chamfering, undercutting, and V-grooving applications. The shank measures 1/2 inch in height and 1/2 inch in width, with a 3.5 inch overall length. The neutral cutting direction makes it suitable for a range of setups without favoring a left- or right-hand cut. Machinists and tool-and-die professionals rely on this tool bit for consistent, repeatable results in production and job-shop environments.

This tool bit is suited for threading and profiling operations on a lathe or CNC turning center. The 60-degree included angle matches standard thread form geometry for common unified and metric thread profiles. Applicable cutting operations include chamfering, threading, undercutting, and V-grooving, making it a versatile choice when a single tool bit must handle multiple finishing and threading tasks on a workpiece. It fits standard E-series tool holders accepting a 1/2 inch shank.

Key Features

• Industry standard E-8 designation for direct replacement in compatible E-series holders
• C6 solid carbide tip for high wear resistance and extended tool life in ferrous and non-ferrous cutting
• 60-degree included angle supports standard threading, V-grooving, and chamfering profiles
• Neutral cutting direction accommodates flexible setup orientation
• Compact 3.5 inch overall length suits tight toolpost and turret clearances
• Consistent 1/2 inch square shank for rigid, repeatable seating in the tool holder

Compatibility

Designed as an OEM-style replacement or direct-fit tool bit for E-series single-point tool holders accepting a 1/2 inch square shank, conforming to industry standard number E-8.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Before changing or indexing a tool bit, power down the lathe or turning center and confirm the spindle is fully stopped. Seat the shank fully in the tool holder and secure all clamping screws evenly before resuming operation. Verify tool height alignment to centerline before taking a cut, as improper height affects thread form accuracy and tool life.
