Accupro B1601000R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B1601000R is a corner radius boring bar designed for precision internal boring operations on small-diameter features. Machined from submicron-grade solid carbide, it delivers the rigidity and wear resistance needed for tight-tolerance work in hardened or abrasive materials. The bar cuts right hand and accepts a minimum bore diameter of 0.16 inches, with a maximum bore depth of 1 inch. Corner radius range runs from 0.0050 to 0.0080 inches, making it well suited for applications where a controlled blend radius at the bottom of a bored feature is required. Shank diameter is 3/16 inches with an overall length of 2 inches. A bright finish coating is applied at the factory.

This boring bar is used in CNC machining centers, manual lathes, and small-bore turning operations where access is limited and dimensional control is critical. It is a common choice for tool and die work, mold component machining, and precision part production where bore finish and corner geometry must be held to close tolerances. Right-hand cutting orientation suits standard spindle rotation on most turning and milling setups. Its compact shank and short overall length make it practical for deep-reach situations within the 1-inch depth limit.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life
• Minimum bore diameter of 0.16 inches for small-feature internal machining
• Corner radius range of 0.0050 to 0.0080 inches for controlled blend geometry
• Right-hand cutting direction compatible with standard spindle rotation
• Bright finish coating applied as manufactured
• Compact 3/16-inch shank diameter and 2-inch overall length for confined setups

Compatibility

Designed as a direct-fit replacement or tooling addition for right-hand boring bar holders accepting a 3/16-inch shank diameter in CNC turning centers, manual lathes, and small-bore milling setups.

Installation Notes

Installation is performed by qualified machinists familiar with boring bar setup and workholding procedures. Ensure the machine spindle is fully stopped and all power is isolated before mounting or removing the bar from the tool holder. Confirm shank seating depth and runout with a dial indicator before taking a first cut. Follow the machine tool manufacturer guidelines for toolholder clamping torque and overhang limits appropriate to this shank diameter.
