Value Collection 383-6212 ER-6 Single-point Threading Tool Bit

Product Description

The VALUE COLLECTION 383-6212 is an ER-style single-point tool bit designed for offset threading and V-grooving operations on a lathe. The bit features a solid carbide tip rated at grade C2, providing the hardness and wear resistance needed for threading ferrous and non-ferrous materials. The shank measures 3/8 inches in both height and width, and the overall length is 2.5 inches. The 60-degree included angle makes it suitable for standard thread-form cutting. The right-hand cutting direction means material is fed from right to left during the cut. Machinists and toolroom operators use this style of bit for threading to a shoulder where clearance is limited.

This tool bit is intended for use in manual and CNC lathes equipped to accept a 3/8-inch square shank tool holder. The ER-6 designation identifies the tool bit profile, which is matched to offset threading and V-grooving to a shoulder. It is suited for job shop threading work, maintenance machining, and production threading where a solid carbide tip is preferred over brazed or inserted alternatives. The compact 2.5-inch overall length fits standard toolposts commonly found on manual engine lathes and small CNC turning centers.

Key Features

Compatibility

Designed as a direct-fit replacement for ER-6 style offset threading tool bit applications requiring a 3/8-inch square shank and right-hand cutting direction.

Installation Notes

Installation is performed by a machinist or toolroom operator. Secure the tool bit firmly in the tool holder before engaging the workpiece, and verify the cutting edge is set at the correct center height relative to the spindle axis. Inspect the carbide tip for chips or cracks before use, and never use a damaged tip. Power down and lock out the lathe before changing or adjusting tool bits in the toolpost.
