Accupro ACC-BB060150G Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB060150G is a micrograin solid carbide boring bar designed for small-diameter internal turning and boring operations. With a minimum bore diameter of 0.06 inches and a maximum bore depth of 0.15 inches, this bar is built for precision work in tight bores where standard tooling cannot reach. The 1/8-inch shank diameter and 1-1/2-inch overall length make it well suited for CNC lathes and manual turning centers handling small-part and micro-bore applications. A titanium nitride (TiN) finish coating improves surface hardness and extends cutting tool life across ferrous and non-ferrous workpiece materials. Right-hand cut geometry follows standard toolholder orientation for conventional lathe setups.

This boring bar is intended for machining professionals and toolroom operators performing precision internal boring on small-diameter features. Typical applications include bearing bores, hydraulic component ports, instrument-grade turned parts, and similar close-tolerance internal features. The micrograin carbide substrate provides consistent edge integrity at fine chip loads, making it appropriate for finishing passes where dimensional accuracy and surface finish are critical. This tool is sold individually and fits standard 1/8-inch boring bar holders.

Key Features

• Micrograin solid carbide substrate for consistent edge sharpness at fine chip loads
• TiN finish coating improves wear resistance and extends tool life
• 0.06 inches minimum bore diameter enables access to very small internal features
• Right-hand cut geometry for standard lathe and CNC turning center setups
• 1/8-inch shank diameter fits common small-bore toolholders
• Compact 1-1/2-inch overall length minimizes overhang in tight setups

Compatibility

Designed for use in standard 1/8-inch boring bar toolholders on CNC lathes and manual turning centers performing small-diameter internal boring operations.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with turning center setup and toolholder torque procedures. Always power down and lock out the machine spindle before mounting or removing tooling. Secure the shank fully within the toolholder bore to minimize overhang and reduce chatter risk. Verify tool height alignment to centerline before commencing a cut.
