Accupro ACC-BBL1801500 Boring Bar Solid Carbide Left Hand

Product Description

The ACCUPRO ACC-BBL1801500 is a solid carbide boring bar designed for precision internal boring operations on CNC and manual lathes. Built from micrograin solid carbide with a bright finish, it delivers consistent cutting performance in tight-bore applications. The bar features a left-hand cutting direction, a minimum bore diameter of 0.18 inches, and a maximum bore depth of 1.5 inches. With a 0.25-inch shank diameter and an overall length of 2.5 inches, this bar is sized for compact toolholders and small-bore work where rigidity and accuracy are critical.

This boring bar is suited for machining small-diameter internal features in ferrous and non-ferrous materials. Its micrograin carbide construction handles interrupted cuts and abrasive materials better than standard carbide grades. The left-hand configuration makes it appropriate for specific toolholder orientations or back-boring setups. Machinists working on precision components, valve bodies, hydraulic fittings, and similar small-bore parts will find this bar a practical fit for production and repair work.

Key Features

• Micrograin solid carbide construction for improved wear resistance and edge retention
• Left-hand cutting direction for back-boring or left-hand toolholder setups
• Minimum bore diameter of 0.18 inches enables access to very small internal features
• Maximum bore depth of 1.5 inches supports through and blind bore applications
• Bright finish coating with no additional coating buildup to maintain dimensional accuracy
• 0.25-inch shank diameter compatible with standard small-bore toolholders

Compatibility

Designed as an OEM-style replacement and standard tooling option for lathes and boring machines accepting a 0.25-inch shank boring bar with left-hand cutting orientation.

Installation Notes

Installation is performed by qualified machinists. Secure the shank firmly in the toolholder to the specified gripping length to minimize overhang and chatter. Power down and lock out the machine spindle before inserting or adjusting the boring bar. Inspect the cutting edge for chips or wear before each use, as solid carbide is brittle and should not be used if the edge is damaged.
