Accupro B110200R Corner Radius Boring Bar Submicron Carbide

Product Description

The ACCUPRO B110200R is a corner radius boring bar designed for precision internal boring operations requiring tight corner geometry control. Machined from submicron-grade solid carbide, it delivers the rigidity and wear resistance needed for accurate, repeatable cuts in small-diameter bores. The bar has a minimum bore diameter of 0.11 inches and a maximum bore depth of 13/64 inches (0.200 inches), with a corner radius range of 0.0030 to 0.0050 inches. The bright finish coating reduces friction and aids chip evacuation. At 1-1/2 inches overall length with a 1/8-inch shank diameter, this bar is suited for small, precise applications where tool geometry and runout tolerance are critical.

This boring bar is used in CNC machining centers, manual lathes, and precision boring setups where small internal diameters with controlled corner radii are required. It is commonly applied in tool and die, mold making, and precision component manufacturing. The right-hand cutting direction makes it compatible with standard spindle rotation. Its compact size and submicron carbide construction make it a reliable choice for machinists working with ferrous and non-ferrous materials in tight bore applications.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life
• Corner radius range of 0.0030 to 0.0050 inches for controlled internal geometry
• Minimum bore diameter of 0.11 inches suits small, tight-tolerance applications
• Maximum bore depth of 13/64 inches (0.200 inches)
• Bright finish coating reduces friction and promotes chip flow
• Right-hand cut configuration for standard spindle rotation setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for 1/8-inch shank boring bar setups on CNC lathes, machining centers, and manual boring equipment requiring right-hand cut, corner radius geometry.

Installation Notes

Installation should be performed by a qualified machinist following the equipment manufacturer's tool-holding specifications. Secure the 1/8-inch shank firmly in the appropriate tool holder or boring head, ensuring minimal overhang to reduce deflection. Power down and lock out the machine before mounting or removing the boring bar. Verify spindle rotation direction matches the right-hand cut orientation before initiating a cut.
