Accupro B3601250R Corner Radius Boring Bar Submicron Carbide

Product Description

The ACCUPRO B3601250R is a corner radius boring bar machined from submicron-grade solid carbide, designed for internal boring operations requiring a controlled corner radius profile. It cuts right-hand direction and handles minimum bore diameters starting at 0.36 inches, with a maximum bore depth of 1.25 inches. The 3/8-inch shank diameter and 2.5-inch overall length make it well-suited for compact setups on CNC lathes and boring machines. A bright finish coating is applied to the flute and shank. Corner radius range runs from 0.005 to 0.008 inches, giving machinists precise control over internal corner geometry on finished bores.

This boring bar is intended for use in precision machining environments where internal bore finish and corner radius accuracy are critical. Typical applications include producing close-tolerance bores in ferrous and non-ferrous workpieces on CNC turning centers or manual lathes. The submicron carbide grade supports demanding cuts where tool wear resistance and edge retention are priorities. It is selected by machinists, toolroom operators, and job shop technicians working on components that require consistent internal geometry across production runs.

Key Features

• Submicron solid carbide construction for superior wear resistance and edge retention
• Corner radius range of 0.005 to 0.008 inches for controlled internal corner profiling
• Minimum bore diameter of 0.36 inches suitable for small-bore internal work
• Maximum bore depth of 1.25 inches accommodates typical short-to-medium bore applications
• 3/8-inch shank diameter for compatibility with standard boring bar holders
• Bright finish coating on carbide substrate

Compatibility

Designed as a direct-fit replacement or toolroom addition for standard 3/8-inch boring bar holder setups used in CNC turning and manual lathe applications requiring right-hand internal corner radius cutting.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool turret or holder is locked before inserting or removing the boring bar. Secure the shank firmly in the boring bar holder to the holder manufacturer's specified clamping torque using appropriate tooling screws. Verify tool centerline height and overhang before beginning a cut to avoid chatter or premature edge failure.
