Accupro B050400A Boring Bar 0.05 in Min Bore Solid Carbide

Product Description

The ACCUPRO B050400A is a submicron solid carbide boring bar designed for small-diameter internal boring operations on CNC lathes and turning centers. It features a right-hand cutting direction and an AlTiN (aluminum titanium nitride) finish coating, which improves heat resistance and extends tool life in dry and semi-dry cutting conditions. With a minimum bore diameter of 0.05 inches and a maximum bore depth of 0.4 inches, this bar is suited for tight-tolerance micro-boring work. The 1/8-inch shank diameter and 1-1/2-inch overall length make it a compact tool for precision machining applications in production and job-shop environments.

This boring bar is intended for machinists and toolroom operators performing small-bore finish and semi-finish operations on lathes, turning centers, and boring mills. It handles ferrous and non-ferrous workpiece materials where close diameter tolerances and smooth surface finishes are required. The AlTiN coating makes it particularly effective in harder materials and elevated-temperature cutting conditions. It is a single-piece, solid carbide construction with no inserts to index or replace, which simplifies setup and reduces runout in micro-bore applications.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance in micro-boring
• AlTiN coating improves heat resistance and extends tool life in demanding cuts
• Right-hand cutting direction for standard CNC lathe and turning center use
• Minimum bore diameter of 0.05 inches suits tight-clearance and small-hole applications
• Maximum bore depth of 0.4 inches with a compact 1-1/2-inch overall length
• 1/8-inch shank diameter fits standard small-bore toolholders and collet chucks

Compatibility

Designed for use in CNC lathes, turning centers, and boring mills equipped with toolholders or collet chucks accepting a 1/8-inch shank diameter boring bar.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before mounting or removing the boring bar. Ensure the shank is fully seated and clamped securely in the toolholder to minimize deflection and runout at small bore diameters. Inspect the cutting edge for chips or wear before each use, as solid carbide tooling can be brittle if mishandled during setup.
