Value Collection 383-8706 TRC-5 Boring Tool Bit C6 Carbide

Product Description

The VALUE COLLECTION 383-8706 is a single-point round shank boring tool bit conforming to industry standard TRC-5. It features a C6-grade solid carbide tip brazed to a neutral cutting geometry, making it well suited for internal boring operations on a variety of workpiece materials. The shank measures 5/16 inches in height and 5/16 inches in width, with an overall length of 1.5 inches. The nose radius is 1/64 inch. Machinists and toolroom operators select this style for precision boring passes where a neutral rake keeps cutting forces balanced and predictable. The compact overall length suits smaller boring bar holders and light-duty CNC or manual lathe setups.

This tool bit is designed for boring applications in machine shop, production, and maintenance environments. The TRC-style round shank fits standard round-bore tool holders common on engine lathes and small machining centers. Its neutral cutting direction accommodates straight-in boring approaches without preferential lead angle, giving the operator flexibility in setting up the cut. The C6 carbide grade provides a balance of hardness and toughness appropriate for general-purpose machining of cast iron, non-ferrous metals, and similar materials.

Compatibility

Designed as a TRC-5 industry-standard replacement or direct-use single-point tool bit for round shank boring bar holders accepting a 5/16 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists. Secure the shank fully in the boring bar holder and verify that the tool is clamped before initiating any spindle rotation. Confirm that the machine is powered off and the spindle is locked before inserting or removing the tool bit. Do not exceed the holder manufacturer's recommended depth of engagement for the shank diameter.
