Accupro B3601150A Boring Bar Submicron Solid Carbide Altin

Product Description

The ACCUPRO B3601150A is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and manual turning machines. Built from submicron-grade carbide with an AlTiN coating, this bar delivers high wear resistance and thermal stability during interrupted and continuous cuts. It accepts a minimum bore diameter of 0.36 inches and reaches a maximum bore depth of 1.15 inches. The right-hand cutting direction suits standard spindle-forward turning setups. With a 3/8-inch shank diameter and an overall length of 2.5 inches, it fits compact toolholding systems commonly used in precision machining environments. Machinists and tool-and-die professionals are the primary installers of this tooling.

This boring bar is suited for finishing and semi-finishing small-diameter bores in ferrous and non-ferrous materials. The submicron carbide substrate maintains edge integrity at elevated cutting speeds, making it appropriate for tight-tolerance work in production and job-shop environments alike. The AlTiN coating extends tool life in dry and minimum-quantity lubrication cutting conditions. Typical applications include precision bore sizing in mold components, hydraulic valve bodies, and close-tolerance machined parts where surface finish and dimensional accuracy are critical.

Key Features

• Submicron solid carbide substrate for superior hardness and edge retention
• AlTiN coating provides thermal barrier and oxidation resistance at high cutting speeds
• Right-hand cut configuration for standard spindle-forward turning operations
• 0.36-inch minimum bore diameter enables access to small internal diameters
• 1.15-inch maximum bore depth suits shallow-to-medium bore applications
• 3/8-inch shank diameter fits a wide range of standard boring bar holders

Compatibility

Designed as a direct-fit replacement-style boring bar for standard 3/8-inch boring bar holders used in CNC and manual turning applications. No specific OEM model compatibility data was provided by the manufacturer for this SKU.

Installation Notes

This tooling is installed and set by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and the toolholder is de-energized before mounting or removing the boring bar. The bar must be clamped securely in a properly sized 3/8-inch holder with adequate overhang control to minimize vibration. Do not exceed the boring bar manufacturer recommended depth-of-cut or speed parameters for the workpiece material and coating type in use.
