Value Collection 383-6222 ER-8 Offset Threading Tool Bit

Product Description

The VALUE COLLECTION 383-6222 is a single-point tool bit designed for offset threading and V-grooving operations on metalworking lathes and threading machines. Built to the ER-8 industry standard, it features a C2-grade solid carbide tip brazed to a right-hand cutting configuration. The shank measures 0.5 inches in height and 0.5 inches in width, with an overall length of 3.5 inches. The 60-degree included angle makes it well suited for cutting standard thread profiles and V-groove forms. Machinists and toolroom operators use this bit for threading up to the shoulder, where clearance and precision matter most.

This tool bit is applied in threading and V-grooving operations on manual and CNC lathes in job shop, production machining, and maintenance environments. The ER-8 style is a recognized industry standard for single-point threading inserts and brazed-tip tool bits, making it a straightforward drop-in for setups already tooled to that specification. Its right-hand cutting direction suits standard lathe rotation for external threading applications.

Key Features

• ER-8 industry standard designation for direct toolholder compatibility
• C2-grade solid carbide tip for wear resistance in steel and cast iron threading
• 60-degree included angle for standard thread and V-groove profiles
• Right-hand cutting direction for conventional lathe rotation
• Offset threading style allows threading close to shoulders and flanges
• Compact 3.5-inch overall length for use in tight setups

Compatibility

Designed as an OEM-style replacement or standard toolroom addition for lathes and threading setups accepting ER-8 single-point tool bits with a 0.5-inch square shank.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the tool bit firmly in a compatible ER-8 toolholder or boring bar before operation, and verify that the cutting edge is set at the correct center height for the workpiece. Power down and lock out the lathe before changing or repositioning any tool bit. Inspect the carbide tip for chipping or wear before each use.
