Accupro B3601800R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B3601800R is a corner radius boring bar designed for precision internal turning and boring operations on CNC and manual lathes. Machined from submicron-grade solid carbide, this right-hand cut tool delivers the rigidity and wear resistance required for tight-tolerance bores in ferrous and non-ferrous materials. It handles a minimum bore diameter of 0.36 inches and a maximum bore depth of 1.8 inches. The 3/8-inch shank diameter and 3-inch overall length make it well-suited for small-bore finishing work where tool deflection and surface finish are critical. The bright finish coating reduces friction and supports chip evacuation during the cut.

This boring bar is used in production machining and job shop environments where small-diameter internal features require controlled corner radii. It is appropriate for finish boring operations in tight cavities where standard boring tools cannot achieve the required corner geometry. The corner radius range of 0.0050 to 0.0080 inches makes it suitable for applications demanding minimal stress concentration at bore transitions. Machinists and tooling technicians working on precision components in aerospace, medical, and general metalworking applications will find this tool applicable to their internal turning setups.

Key Features

• Submicron solid carbide construction for superior hardness and thermal resistance in demanding cuts
• Right-hand cutting direction for standard lathe and boring head configurations
• Corner radius range of 0.0050 to 0.0080 inches for controlled internal corner geometry
• Bright finish coating reduces friction and aids chip flow during bore operations
• 3/8-inch shank diameter with 3-inch overall length for compact, rigid tool setup
• Minimum bore diameter of 0.36 inches with maximum bore depth of 1.8 inches

Compatibility

Designed as a standard replacement or addition for tooling setups requiring a 3/8-inch shank corner radius boring bar in right-hand cut orientation on CNC lathes, manual lathes, and boring heads accepting that shank size.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the machine tool manufacturer's setup procedures. Secure the shank firmly in the tool holder to the manufacturer's specified clamping torque to minimize overhang deflection. Ensure the machine spindle is fully stopped and the control is placed in an appropriate safe state before installing or removing the bar. Verify tool centerline height alignment before taking the first cut to avoid chatter and premature edge wear.
