Accupro ACC-BB4901000A Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB4901000A is a right-hand boring bar ground from micrograin solid carbide for precision internal diameter machining. It features a 0.490-inch minimum bore diameter and a 1-inch maximum bore depth, making it well suited for tight-tolerance bore work in small-diameter applications. The 1/2-inch shank diameter provides rigid coupling to standard boring tool holders. Overall length is 3 inches. Machinists and toolroom technicians reach for this bar when consistent surface finish and dimensional accuracy are required in CNC or manual turning and boring operations.

This boring bar is intended for use in machine shops, toolrooms, and production environments where small-bore internal turning is performed. It is appropriate for ferrous and non-ferrous workpieces where micrograin carbide geometry delivers the edge retention and rigidity needed to hold close tolerances. Typical applications include finish boring of housings, bushings, and bored holes requiring precise diameter control in light to moderate cutting conditions.

Key Features

• Micrograin solid carbide construction for superior edge retention and rigidity
• Right-hand cutting direction for standard lathe and boring head setups
• 0.490-inch minimum bore diameter for small-bore applications
• 1-inch maximum bore depth suitable for shallow precision bores
• 1/2-inch shank diameter for secure mounting in compatible tool holders
• 3-inch overall length for compact tooling configurations

Compatibility

Designed as a direct-fit boring bar for tool holders and boring heads accepting a 1/2-inch round shank in CNC and manual turning centers.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or removing the boring bar. Ensure the shank is fully seated and clamped securely in the tool holder to the holder manufacturer's specifications before resuming operation. Inspect the cutting edge for chips or wear before each use.
