Accupro B3202500A Boring Bar 0.32 in Solid Carbide Altin

Product Description

The ACCUPRO B3202500A is a solid carbide boring bar designed for precision internal diameter machining on CNC lathes and boring machines. Built from submicron-grade solid carbide and coated with AlTiN (aluminum titanium nitride), it handles demanding cutting conditions including dry and high-speed operations. The bar accepts a minimum bore diameter of 0.32 inches and reaches a maximum bore depth of 2.5 inches, making it suitable for a range of small-to-mid-size bored features. With a 3/8-inch shank diameter and a 4-inch overall length, it mounts directly into standard boring bar holders and quick-change tooling systems. Right-hand cutting geometry is standard. Machinists and toolroom technicians specify this bar for tight-tolerance work where carbide rigidity and coating hardness are required.

The B3202500A is suited for use in production and toolroom environments on CNC turning centers, manual lathes, and horizontal boring mills. It is commonly applied when machining ferrous and non-ferrous workpieces that require consistent bore geometry and surface finish. The AlTiN coating extends tool life in abrasive and elevated-temperature cutting environments. Its compact shank diameter makes it appropriate for small-bore applications where clearance and deflection control are critical factors in achieving dimensional accuracy.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance in precision boring operations
• AlTiN coating provides elevated heat resistance and extended tool life in abrasive cutting conditions
• Minimum bore diameter of 0.32 inches supports small-bore internal machining applications
• Maximum bore depth of 2.5 inches allows reach into deeper bored features without tool change
• Right-hand cutting direction compatible with standard lathe and CNC turning center spindle rotation
• 3/8-inch shank diameter fits common boring bar holders and quick-change tooling systems

Compatibility

Designed as a direct-fit replacement or toolroom addition for standard 3/8-inch boring bar holders used on CNC turning centers, manual lathes, and boring machines requiring right-hand cutting geometry.

Installation Notes

Installation of boring bars should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tooling turret or holder is de-energized before inserting or removing the bar. Set overhang to the minimum length required for the bore depth to reduce deflection and chatter. Verify shank seating and clamping torque per the toolholder manufacturer specifications before taking any cuts.
