Accupro ACC-BBL180600 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BBL180600 is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and manual turning centers. Built from submicron-grade carbide with a bright finish coating, it delivers consistent cutting performance in tight-tolerance bores starting at 0.18 inches minimum diameter. The left-hand cutting direction suits specific tooling orientations and back-boring applications. With a 0.25 inch shank diameter and an overall length of 2.5 inches, this bar fits compact toolholders and live tooling setups commonly found in small-part machining environments. Machinists and tool-and-die professionals specify this bar for precision internal work where rigidity and edge retention matter.

This boring bar is suited for small-bore internal turning applications in production and job-shop environments. It is well-matched to Swiss-type lathes, CNC turning centers, and manual lathes equipped with appropriate boring bar holders. The 0.18 inch minimum bore diameter makes it applicable for micro-bore work in aluminum, steel, and similar machinable materials. Maximum bore depth reaches 0.6 inches, keeping it focused on shallow, precision bores rather than deep-hole applications. It is packaged and sold individually.

Key Features

• Submicron solid carbide construction for edge retention and resistance to chipping
• Left-hand cutting direction for back-boring and reverse-orientation tooling setups
• 0.18 inch minimum bore diameter for small-diameter internal turning
• 0.6 inch maximum bore depth suited to shallow precision bores
• Bright finish coating reduces built-up edge on non-ferrous and ferrous materials
• 0.25 inch shank diameter fits standard compact boring bar holders

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for standard 0.25 inch boring bar holders used in CNC and manual turning applications requiring left-hand cut geometry.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing or seating the boring bar in its holder. Secure the shank firmly in the toolholder to the holder manufacturer's clamping specifications to prevent deflection during the cut. Verify cutting direction orientation before initiating the first pass, as left-hand geometry requires correct setup to avoid tool crash or workpiece damage.
