Scientific Cutting Tools MB030150A Boring Bar Solid Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS MB030150A is a submicron solid carbide boring bar designed for precision internal turning and bore finishing operations on small-diameter features. With a minimum bore diameter of 0.03 inches and a maximum bore depth of 0.15 inches, this bar is built for tight-tolerance work in micro-machining applications. The 1/8-inch shank diameter keeps the tool compact for use in small turret or gang-tooled setups. An AlTiN+ finish coating improves heat resistance and extends tool life in ferrous and hardened materials. Right-hand cut geometry is standard. This tool is installed and used by machinists and toolroom professionals working on CNC lathes or manual boring machines.

This boring bar is suited for small-bore applications in precision manufacturing environments, including medical component machining, aerospace part production, and instrument manufacturing. The submicron carbide grade delivers consistent edge integrity at fine depths of cut, making it appropriate for finishing passes where surface finish and dimensional accuracy are the priority. Its compact overall length of 1.5 inches suits close-clearance setups where overhang must be minimized to control vibration and deflection.

Key Features

• Minimum bore diameter of 0.03 inches for micro-bore applications
• Maximum bore depth of 0.15 inches suits shallow internal features
• Submicron solid carbide construction for edge stability and wear resistance
• AlTiN+ coating improves thermal resistance and extends cutting life in ferrous materials
• Right-hand cut direction for standard lathe and boring setups
• 1/8-inch shank diameter and 1.5-inch OAL for compact, low-overhang mounting

Compatibility

Designed as an OEM-style precision boring bar for use in CNC lathes and manual boring machines accepting a 1/8-inch shank tool holder.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the shank. Secure the boring bar to the specified clamping torque for the toolholder in use. Verify minimal overhang beyond the holder to reduce deflection, particularly given the small shank diameter.
