Accupro B3601800A Boring Bar 0.36in Min Bore Solid Carbide

Product Description

The ACCUPRO B3601800A is a solid carbide boring bar designed for internal diameter machining in metal cutting and precision machining operations. Built from submicron-grade solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness and heat resistance suited to tight-tolerance boring work. The bar has a minimum bore diameter of 0.36 inches and a maximum bore depth of 1.8 inches. With a 3/8-inch shank diameter and an overall length of 2.5 inches, it fits standard boring bar holders used on CNC lathes and manual turning centers. Right-hand cut geometry makes it suitable for conventional turning setups.

This boring bar is used in machine shops, production environments, and tool rooms for finish and semi-finish boring of small-diameter holes. It is well suited to ferrous and non-ferrous materials where close tolerances and smooth surface finish are required. The AlTiN coating improves wear resistance and extends tool life in dry or minimal-lubrication cutting conditions. Machinists and CNC operators working on lathes, turning centers, or mill-turn machines will find this bar appropriate for small-bore internal operations requiring precise depth control.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance
• AlTiN coating for high-temperature and abrasion resistance
• 0.36 inches minimum bore diameter for small-bore applications
• 1.8 inches maximum bore depth for reach in confined bores
• Right-hand cut geometry for standard turning setups
• 3/8-inch shank diameter fits common boring bar holders

Compatibility

Designed as an OEM-style replacement or direct tooling solution for standard boring bar holders accepting a 3/8-inch shank diameter on CNC lathes and turning centers.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered off and spindle locked. Secure the shank firmly in the boring bar holder to the tool holder manufacturer's recommended clamping procedure before operation. Verify bore diameter and depth settings against the workpiece drawing before engaging the cut. Follow all shop safety protocols and machine tool operating procedures during setup and use.
