Accupro ACC-BB3201500G Boring Bar 0.32in Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB3201500G is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and manual turning centers. Built from micrograin solid carbide and finished with a TiN (titanium nitride) coating, it delivers rigidity and wear resistance in tight-bore applications. The bar supports a minimum bore diameter of 0.32 inches and reaches a maximum bore depth of 1.5 inches. With a 3/8-inch shank diameter and an overall length of 2.5 inches, this tool fits standard boring bar holders used in production and job-shop turning environments. Right-hand cut geometry makes it suitable for conventional lathe rotation setups.

This boring bar is suited for finish and semi-finish boring of small-diameter holes in ferrous and non-ferrous workpieces. The micrograin carbide substrate supports higher cutting speeds and resists chipping in interrupted cuts better than standard carbide grades. Machinists working on precision components where tight bore tolerances are required will find the TiN coating extends tool life across repeat production runs. It fits turning applications in aerospace, automotive, and general machining environments where small-bore accuracy is critical.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention in small-bore work
• TiN coating increases surface hardness and reduces built-up edge on cutting surfaces
• Minimum bore diameter of 0.32 inches suits tight internal diameter requirements
• Maximum bore depth of 1.5 inches covers typical small-part turning applications
• Right-hand cut geometry for standard lathe rotation setups
• 3/8-inch shank diameter fits common boring bar toolholders without adapters

Compatibility

Designed as an OEM-style replacement or direct tooling addition for turning centers and lathes equipped with standard 3/8-inch boring bar holders accepting solid carbide bars up to 2.5 inches overall length.

Installation Notes

Installation is performed by qualified machinists or tooling setup technicians. Power down and lock out the machine spindle before seating or removing the boring bar from the toolholder. Verify shank clamp torque against the machine manufacturer's toolholder specifications before cutting. Inspect the cutting edge and TiN coating for chips or wear before each use, as a damaged edge on a solid carbide tool can affect bore finish and dimensional accuracy.
