Accupro B080150R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B080150R is a corner radius boring bar designed for precision internal machining in tight-bore applications. Manufactured from submicron-grade solid carbide, it delivers the rigidity and wear resistance required for consistent, accurate cuts in hardened and abrasive materials. The bar features a right-hand cutting direction and a bright finish with no additional coating. With a minimum bore diameter of 0.08 inches and a maximum bore depth of 0.15 inches, this tool is built for small-diameter, shallow-bore work where dimensional accuracy is critical. Machinists and toolroom technicians use it wherever a controlled corner radius profile is required at the bore entry or bottom.

This boring bar fits CNC turning centers, manual lathes, and small boring machines equipped to accept a 1/8-inch shank. It is suited for precision shops, mold and die work, and aerospace or medical component machining where fine bore tolerances and repeatable corner geometry are essential. The 0.003 to 0.005 inch corner radius range allows for controlled edge-break and stress-relief profiles in bored features. It is sold individually and is appropriate for applications where a submicron carbide grade is specified for extended tool life in challenging materials.

Key Features

• Submicron solid carbide construction for high rigidity and wear resistance in small-bore applications
• Right-hand cutting direction for standard lathe and boring machine setups
• 0.08 inch minimum bore diameter suitable for tight internal features
• 0.003 to 0.005 inch corner radius range for precise edge geometry control
• Bright finish with no coating for clean chip flow and dimensional predictability
• Compact 1-1/2 inch overall length reduces overhang and deflection risk

Compatibility

Designed for use in lathes and boring machines accepting a 1/8-inch round shank boring bar, with a maximum bore depth of 0.15 inches and a minimum bore diameter of 0.08 inches.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before mounting the bar. Secure the shank with appropriate clamping force per the toolholder manufacturer specification to prevent slippage during cuts. Confirm bore depth and diameter are within the tool rating before beginning any operation to avoid overloading the carbide.
