Accupro B3201100A Boring Bar 0.32 in Solid Carbide Altin

Product Description

The ACCUPRO B3201100A is a solid carbide boring bar engineered for precision internal diameter machining. Built from submicron-grade carbide and finished with an AlTiN coating, it delivers extended tool life in hard and abrasive workpiece materials. The right-hand cutting orientation suits standard CNC and manual boring operations. With a minimum bore diameter of 0.32 inches and a maximum bore depth of 1.1 inches, this bar handles tight internal features where rigidity and dimensional accuracy are critical. The 3/8-inch shank diameter and 2.5-inch overall length make it compatible with a wide range of boring head setups and toolholders used in production and job-shop environments.

This boring bar is suited for ferrous and non-ferrous machining applications where fine surface finish and close tolerances are required. The AlTiN coating provides thermal resistance, making it effective in dry or semi-dry cutting conditions. Machinists working with CNC lathes, machining centers, or manual boring mills will find this bar appropriate for finish and semi-finish boring passes in steel, cast iron, and similar materials.

Key Features

• Submicron solid carbide construction for high rigidity and wear resistance
• AlTiN coating for elevated thermal hardness and extended tool life
• Right-hand cut orientation for standard boring operations
• 0.32-inch minimum bore diameter enables machining of small internal features
• 1.1-inch maximum bore depth suits a range of shallow to moderate internal cuts
• 3/8-inch shank diameter fits common boring head and toolholder configurations

Compatibility

Designed as an OEM-style replacement and direct-fit boring bar for toolholders and boring heads accepting a 3/8-inch round shank. Confirm minimum bore diameter and maximum depth requirements against your specific application before installation.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Power down and lock out the machine before mounting or adjusting the boring bar in the toolholder. Ensure the shank is properly seated and clamped to the manufacturer-specified engagement depth to minimize runout and chatter. Verify bore diameter and depth clearances against the workpiece setup before initiating a cut.
