Value Collection 383-6232 ER-5 Threading Tool Bit 5/16 in

Product Description

The VALUE COLLECTION 383-6232 is an ER-style single-point tool bit designed for offset threading and V-grooving operations on a lathe or threading machine. Built to ER-5 industry standards, it features a solid carbide tip rated C2 grade, delivering the hardness and edge retention needed for threading ferrous and non-ferrous materials. The shank measures 5/16 inches in height and 5/16 inches in width, with an overall length of 2.25 inches. The 60-degree included angle makes it suitable for standard unified thread forms. Right-hand cutting direction suits conventional threading setups where the tool feeds from right to left.

This tool bit is intended for threading and V-grooving to shoulder applications where precise thread profile control is required. It is commonly used in production machine shops, maintenance and repair operations, and toolroom environments. The ER-5 designation aligns it with standard toolholder systems that accept this insert style. Machinists working on small-diameter workpieces will find the 5/16-inch shank size appropriate for compact tooling setups on bench lathes and turret lathes.

Key Features

• ER-5 industry standard designation for direct replacement and toolholder compatibility
• C2 solid carbide tip for hardness and wear resistance across threading applications
• 60-degree included angle for standard unified and V-groove thread profiles
• Right-hand cutting direction for conventional left-to-right feed threading operations
• Compact 2.25-inch overall length suited to small-shank tooling setups
• Offset threading style allows threading close to shoulders without interference

Compatibility

Designed as a standard ER-5 single-point threading tool bit for use in toolholders and lathes accepting a 5/16-inch square shank. Suited for threading and V-grooving to shoulder applications on compatible manual and CNC turning equipment.

Installation Notes

Installation should be performed by a qualified machinist familiar with single-point threading setups. Ensure the lathe spindle and feed drive are fully stopped and the machine is locked out before securing the tool bit in the holder. The tool bit must be set to center height relative to the workpiece axis before commencing threading passes. Refer to the machine manufacturer guidelines and applicable ANSI safety standards for tooling setup procedures.
