Accupro MB045150 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO MB045150 is a solid carbide boring bar designed for precision internal boring operations on small-diameter features. Built from submicron-grade carbide with a bright finish, it delivers consistent tool life and dimensional accuracy in tight-bore applications. The right-hand cutting direction suits standard CNC and manual lathe setups. With a minimum bore diameter of 0.045 inches and a maximum bore depth of 0.15 inches, this bar targets fine-detail work where rigidity and geometry repeatability are critical. Machinists and toolroom technicians working with small-bore components will find this bar suited to high-precision finishing and semi-finishing passes.

This boring bar is intended for small-bore internal turning operations in ferrous and non-ferrous materials where tight tolerances and smooth surface finish are required. The 1/8-inch shank diameter and 1-1/2-inch overall length make it compatible with compact toolholders and small-bore heads common in CNC turning centers and manual engine lathes. Typical applications include precision bore finishing, spotting, and cleanup passes on features too small for standard indexable tooling.

Key Features

• Submicron solid carbide construction for superior wear resistance and edge retention
• Minimum bore diameter of 0.045 inches for tight, small-feature boring
• Maximum bore depth of 0.15 inches
• Right-hand cutting direction for standard lathe and turning center compatibility
• Bright finish coating reduces built-up edge and aids chip flow
• 1/8-inch shank diameter fits compact toolholding systems

Compatibility

Designed for use in toolholders and boring heads accepting a 1/8-inch round shank, commonly found on CNC turning centers and manual lathes configured for small-bore internal turning operations.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before mounting or removing the boring bar. Ensure the shank is fully seated and clamped securely in the toolholder to minimize overhang-related deflection, which is critical at small bore diameters. Follow the machine manufacturer guidelines for speeds and feeds appropriate to solid carbide tooling.
