Scientific Cutting Tools PB180500A Profile Boring Bar

Product Description

The SCIENTIFIC CUTTING TOOLS PB180500A is a profile boring bar machined from submicron-grade solid carbide and designed for precision internal profiling operations on CNC lathes and machining centers. It features a right-hand cutting direction, a 0.18-inch minimum bore diameter, and a maximum bore depth of 0.5 inches. The bar carries an AlTiN+ finish coating that extends tool life in ferrous and hardened materials by reducing heat buildup at the cutting edge. A 0.01-inch corner radius delivers clean, consistent internal profiles. Machinists, toolroom technicians, and CNC operators install this bar in standard tool holders for close-tolerance boring work.

This boring bar is suited for small-diameter internal profiling where conventional insert tooling cannot reach. It is commonly used in production turning and toolroom environments on materials including steel, stainless steel, cast iron, and hardened alloys. The 3/16-inch shank diameter fits standard boring bar holders accepting that shank size, and the 2-inch overall length accommodates typical short-reach setups on CNC lathes and mill-turn machines. Right-hand cut geometry is the standard orientation for conventional front-turning tool post setups.

Key Features

• Submicron solid carbide construction for high rigidity and wear resistance in demanding materials
• AlTiN+ coating reduces thermal load and extends cutting life in ferrous and hardened workpieces
• 0.18-inch minimum bore diameter enables internal profiling in small-diameter bores
• 0.01-inch corner radius for precise, repeatable internal profile geometry
• Right-hand cut direction compatible with standard CNC lathe tool post orientation
• 3/16-inch shank diameter fits common small-bore toolholders without adapters

Compatibility

Designed as an OEM-style solid carbide profile boring bar for use in CNC lathes and machining centers equipped with toolholders accepting a 3/16-inch shank diameter.

Installation Notes

A qualified machinist or CNC toolroom technician should install and set this boring bar. Power down and lock out the machine spindle before inserting or removing the bar from the toolholder. Ensure the shank is fully seated and the set screw torqued per the toolholder manufacturer specification before running. Confirm bore depth and diameter clearance before initiating a cut to avoid tool deflection or workpiece interference.
