Accupro B3603000R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B3603000R is a corner radius boring bar designed for precision internal turning operations on CNC lathes and machining centers. Machined from submicron-grade solid carbide, this bar delivers the rigidity and wear resistance needed for tight-tolerance bores. It accepts a minimum bore diameter of 0.36 inches and reaches a maximum bore depth of 3 inches, making it suitable for a wide range of internal profiling and finishing passes. The right-hand cutting direction suits standard spindle rotation setups. With a corner radius range of 0.0050 to 0.0080 inches, this bar produces clean, controlled blends at bore transitions without stress risers.

This boring bar is used in job shops, production machining environments, and toolrooms where internal diameter work demands consistent dimensional accuracy. It is well suited to finishing operations on steel, stainless, aluminum, and similar machinable materials where a controlled corner radius is a print requirement. The 3/8-inch shank diameter fits standard boring bar holders and quick-change tooling systems commonly found on manual and CNC turning equipment. The 4-inch overall length provides clearance for typical chuck and turret setups.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life
• Corner radius range of 0.0050 to 0.0080 inches for controlled bore-floor transitions
• Minimum bore diameter of 0.36 inches suits small to mid-range internal work
• Maximum bore depth of 3 inches covers common production bore lengths
• Right-hand cut orientation for standard spindle rotation
• Bright finish coating - no additional coating interference with dimensional tolerances

Compatibility

Designed as a direct-fit boring bar for standard 3/8-inch boring bar holders and quick-change tooling systems on CNC and manual turning equipment. Confirm holder bore size and overhang requirements before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing the bar from the holder. Minimize overhang beyond the holder to reduce chatter and deflection during the cut. Follow the machine tool manufacturer guidelines for tool clamping torque and runout inspection prior to cutting.
