Accupro ACC-BB080150G Boring Bar Micrograin Carbide Tin

Product Description

The ACCUPRO ACC-BB080150G is a solid carbide boring bar designed for precision internal boring operations on CNC and manual lathes. Built from micrograin solid carbide and finished with a titanium nitride (TiN) coating, this bar delivers consistent cutting performance in tight-tolerance bore applications. It accepts a minimum bore diameter of 0.08 inches and reaches a maximum bore depth of 0.15 inches. The right-hand cutting direction suits standard lathe setups. With a shank diameter of 0.125 inches and an overall length of 1.5 inches, this tool is sized for small-bore work where rigidity and dimensional accuracy are critical.

This boring bar is suited for machining small-diameter internal features in ferrous and non-ferrous materials. It is a practical choice for prototype work, short-run production, and repair machining where a compact, high-hardness cutting tool is required. The TiN coating extends tool life by reducing friction and heat buildup at the cutting edge. Machinists working on watch components, medical parts, hydraulic fittings, or similar precision small-bore applications will find this tool appropriate for their setups.

Key Features

• Micrograin solid carbide construction provides superior hardness and edge retention compared to standard carbide grades
• TiN finish coating reduces friction and improves tool life in high-cycle boring operations
• Minimum bore diameter of 0.08 inches enables work in very small internal features
• Right-hand cutting direction compatible with standard lathe rotation
• Compact 0.125-inch shank diameter and 1.5-inch overall length for use in tight setups and small machine spindles
• Single-piece solid carbide body eliminates insert seating variability

Compatibility

Designed as an OEM-style replacement or direct-fit tooling solution for lathes and boring machines that accept a 0.125-inch round shank boring bar with right-hand cutting direction.

Installation Notes

Installation and setup should be performed by a qualified machinist familiar with lathe tooling and boring bar protocols. Secure the shank firmly in the tool holder and verify overhang is minimized to reduce vibration during the cut. Power down and lock out the machine spindle before mounting or removing the boring bar. Follow applicable shop safety procedures and machine manufacturer guidelines when setting cutting parameters.
