Accupro ACC-BB3201600G Boring Bar Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB3201600G is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Machined from micrograin solid carbide, this bar delivers the rigidity and edge retention needed for tight-tolerance bores in ferrous and non-ferrous materials. A titanium nitride (TiN) finish coating improves wear resistance and reduces friction at the cutting edge. The right-hand cutting orientation and 0.375-inch shank diameter make it a standard fit for most tool holders in that size class. Minimum bore diameter is 0.32 inches with a maximum bore depth of 1.6 inches. Overall length is 2.5 inches. Machinists and CNC operators install this bar when close-tolerance bore finishing is required.

This boring bar is suited for light to medium internal turning and bore finishing applications in job shop and production environments. The compact 2.5-inch overall length and 0.32-inch minimum bore diameter make it appropriate for small-diameter work where reach and clearance are both critical. Right-hand cut orientation means it feeds from right to left in standard lathe setup. It is installed by machinists and CNC turning technicians handling precision bore work in steel, cast iron, aluminum, and similar machinable materials.

Key Features

• Micrograin solid carbide construction for improved rigidity and edge retention over high-speed steel alternatives
• TiN finish coating reduces friction and extends tool life in continuous cutting applications
• 0.32-inch minimum bore diameter suits small-bore finishing and light internal turning
• 1.6-inch maximum bore depth provides adequate reach for short to medium internal features
• 0.375-inch shank diameter fits standard right-hand boring bar tool holders
• Right-hand cutting direction for conventional lathe and CNC turning center setups

Compatibility

Designed for use in standard boring bar tool holders accepting a 0.375-inch shank diameter. Compatible with CNC lathes and manual turning centers configured for right-hand internal boring operations.

Installation Notes

Installation is performed by a qualified machinist or CNC turning technician. Secure the shank fully in the tool holder and minimize overhang to reduce chatter and deflection during the cut. Confirm spindle speed and feed rate are appropriate for the workpiece material before engaging the cut. Always power down and lock out the machine before changing or adjusting tooling.
