Accupro B1801100A Boring Bar 0.18in Min Bore Solid Carbide

Product Description

The ACCUPRO B1801100A is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade carbide and coated with AlTiN for heat resistance and extended tool life, it handles tight-tolerance bore work in hardened steels, stainless alloys, and cast iron. The right-hand cutting geometry suits standard spindle rotation. With a 0.18-inch minimum bore diameter and 1/4-inch shank, this bar fits compact toolholders used in small-bore finishing applications. Overall length is 2.5 inches, keeping the tool rigid and chatter-resistant at depth.

This boring bar is suited for production machining, toolroom work, and repair-shop turning where small internal diameters require tight surface finish and dimensional accuracy. It is most commonly installed in CNC turning centers, engine lathes, and Swiss-style machines using 1/4-inch shank boring bar holders. The 1.1-inch maximum bore depth accommodates through-bores and blind bores in short to medium workpieces. Machinists working in aerospace, automotive, hydraulic component, and general precision machining shops will find this bar appropriate for finishing passes on small bores.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance in difficult materials
• AlTiN coating provides oxidation resistance and reduces heat buildup at the cutting edge
• 0.18-inch minimum bore diameter for small internal features
• Right-hand cutting direction for standard spindle rotation
• 1/4-inch shank diameter fits common compact boring bar holders
• 2.5-inch overall length minimizes overhang and reduces deflection

Compatibility

Designed for use in 1/4-inch shank boring bar holders on CNC turning centers, engine lathes, and similar machine tools requiring small-bore internal turning capability.

Installation Notes

Installation should be performed by a qualified machinist familiar with turning tool setup and machine tool operation. Secure the shank fully within the toolholder to the recommended minimum engagement depth before operation. Ensure the machine spindle is fully stopped and the machine is in a safe state before changing or adjusting tooling. Follow the machine manufacturer guidelines and applicable shop safety procedures when setting tool offsets and running first-piece verification cuts.
