Accupro B3602000R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B3602000R is a corner radius boring bar designed for internal turning operations that require a controlled corner radius profile at the base of a bored feature. Machined from submicron-grade solid carbide, this bar offers the rigidity and wear resistance needed for tight-tolerance work in hardened materials and difficult-to-machine alloys. It handles a minimum bore diameter of 0.36 inches and reaches a maximum bore depth of 2 inches. The 3/8-inch shank diameter and 4-inch overall length suit it to CNC lathes and boring mills where tool overhang and clearance are critical setup factors. Machinists and toolroom operators use this bar when a square-shoulder insert won't produce the required blend radius.

This boring bar fits production and job-shop environments running internal diameter work on CNC turning centers or manual lathes equipped with a 3/8-inch boring bar holder. It is intended for right-hand cutting direction and is well suited to finish boring passes where a corner radius between 0.005 and 0.008 inches must be held consistently. Applications include precision bores in ferrous and non-ferrous workpieces where surface finish and dimensional accuracy at the bore floor are required.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life
• Corner radius range of 0.005 to 0.008 inches for controlled blend at bore base
• Minimum bore diameter of 0.36 inches suits small-diameter internal work
• Maximum bore depth of 2 inches covers a broad range of part geometries
• Bright/uncoated finish allows direct inspection of tool condition and edge prep
• Right-hand cutting direction for standard CNC lathe and boring mill setups

Compatibility

Designed for use in 3/8-inch boring bar holders on CNC turning centers and manual lathes configured for right-hand internal cutting operations.

Installation Notes

This boring bar is installed by qualified machinists or toolroom technicians. Power down and lock out the spindle before mounting or adjusting the bar in the tool holder. Ensure the shank is properly supported in the holder with minimal overhang beyond what the bore depth requires, as excessive overhang increases deflection and chatter. Follow the machine tool manufacturer's guidelines for boring bar clamping torque and tool offset entry before taking a cut.
