Value Collection 383-6216 ER-6 Offset Threading Tool Bit

Product Description

The VALUE COLLECTION 383-6216 is a single-point ER-style offset threading tool bit designed for threading and V-grooving operations on lathes and turning centers. Built with a C6 solid carbide tip brazed to a steel shank, this bit delivers the hardness and wear resistance required for cutting threads in ferrous and non-ferrous materials. The shank measures 3/8 inches in height and 3/8 inches in width, with an overall length of 2.5 inches. The 60-degree included angle is standard for unified and metric thread forms. Machinists and tool-and-die professionals install this style of bit in lathe tool posts for precision threading passes.

This tool bit suits turning applications where threading or V-grooving to a shoulder is required. The right-hand cutting direction means the tool advances from right to left toward the chuck, which is the standard orientation for the majority of external and internal threading operations on manual and CNC lathes. The ER-6 industry standard designation makes it straightforward to source as a direct drop-in replacement in shops already running ER-series tooling. It is appropriate for general-purpose production threading in light to medium-duty turning environments.

Key Features

• C6 solid carbide tip for extended wear life in threading applications
• 60-degree included angle compatible with unified and metric thread forms
• Offset threading style enables threading and V-grooving to a shoulder
• Right-hand cutting direction for standard lathe feed orientation
• 3/8 inch square shank fits common lathe tool post holders
• Compact 2.5-inch overall length for use in tooling setups with limited clearance

Compatibility

Designed as an OEM-style replacement for ER-6 single-point threading tool bits used in standard 3/8 inch tool post holders on manual and CNC lathes.

Installation Notes

Installation is performed by qualified machinists. Before mounting, power down and lock out the lathe spindle drive per the machine manufacturer's lockout/tagout procedure. Secure the shank firmly in the tool post holder so the carbide tip is on center with the workpiece axis. Inspect the carbide tip for chips or cracks before each use — a damaged tip should not be placed in service.
