Value Collection 383-8702 Boring Tool Bit TRC-5 5/16 in

Product Description

The VALUE COLLECTION 383-8702 is a single-point round shank boring tool bit conforming to industry standard TRC-5. Built with a C2 solid carbide tip brazed to a neutral cutting geometry, this bit delivers consistent stock removal in boring operations where precision and tip durability are priorities. The shank measures 5/16 inches in both height and width, and overall length is 1-1/2 inches. The 1/64-inch nose radius suits general-purpose boring where a fine surface finish is required. Machinists and tooling technicians install this bit in boring bars and holders sized to accept a 5/16-inch round shank.

This tool bit is suited to light-duty boring applications on lathes and boring mills in job shop, maintenance, and production environments. The TRC-style round shank design fits standard boring bar holders for 5/16-inch shanks. The neutral cutting direction allows the bit to be oriented for both left-hand and right-hand cutting setups, making it adaptable across a range of setups without requiring a dedicated handed bit. Typical work materials for C2 grade carbide include cast iron, non-ferrous metals, and general-purpose steels at moderate cutting speeds.

Key Features

• C2 grade solid carbide tip for extended wear resistance compared to high-speed steel
• Neutral cutting direction for flexible left- or right-hand setup orientation
• TRC-5 industry standard number for straightforward cross-referencing and replacement
• 1/64-inch nose radius suited to general-purpose boring surface finish requirements
• Compact 1-1/2-inch overall length fits tight boring bar configurations
• 5/16-inch square shank profile fits standard round shank boring holders

Compatibility

Designed as a replacement or direct-fit boring tool bit for boring bars and holders accepting a 5/16-inch round shank, conforming to TRC-5 industry standard dimensions.

Installation Notes

Installation is performed by machinists or tooling technicians. Power down and lock out the machine spindle before seating or removing the bit from the boring bar holder. Secure the shank fully within the holder bore and tighten set screws to the holder manufacturer specification before engaging the cut. Inspect the carbide tip for cracks or chipping before each use, as damaged carbide can fracture under cutting load.
