Accupro MB030100 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO MB030100 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade carbide, this bar delivers the rigidity and wear resistance needed to hold tight tolerances in small-bore applications. It features a right-hand cutting direction and a bright, uncoated finish suited for a range of workpiece materials. With a 0.03-inch minimum bore diameter and a 0.1-inch maximum bore depth, the MB030100 is optimized for very fine, shallow bores where dimensional accuracy is critical. A 1/8-inch shank diameter and 1.5-inch overall length make it compatible with small-bore toolholders on production and toolroom equipment.

This boring bar is used in precision machining environments where small internal diameters must be bored to close tolerances. Typical applications include instrument components, medical device parts, small hydraulic fittings, and other workpieces requiring fine internal finishes at minimal bore diameters. It is installed by machinists and toolroom technicians working on CNC or manual turning equipment. The compact geometry is well suited to production shops, job shops, and toolrooms where small-part machining is routine.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life
• 0.03-inch minimum bore diameter for very fine internal boring
• 0.1-inch maximum bore depth suited to shallow-bore applications
• Right-hand cutting direction for standard lathe setups
• Bright, uncoated finish compatible with a wide range of workpiece materials
• 1/8-inch shank diameter fits small-bore toolholders

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for small-bore toolholders accepting a 1/8-inch shank diameter on CNC and manual turning centers.

Installation Notes

This boring bar is installed by qualified machinists following standard turning-center setup procedures. Secure the shank firmly in a compatible toolholder and verify runout before cutting. Always power down and lock out the machine spindle before inserting or removing tooling. Follow shop-standard feeds and speeds for carbide tooling and inspect the cutting edge for wear or chipping between operations.
