Accupro ACC-BB160500A Boring Bar 0.16in Min Bore Carbide

Product Description

The ACCUPRO ACC-BB160500A is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from micrograin carbide stock and finished with a TiAlN coating, this bar delivers extended tool life and heat resistance in ferrous and non-ferrous materials. It handles a minimum bore diameter of 0.16 inches and a maximum bore depth of 0.50 inches, making it a practical choice for tight, shallow bore applications. The 3/16-inch shank diameter and 2-inch overall length suit compact tooling setups where clearance is limited. Machinists and toolroom technicians specify this bar for repetitive finish-boring and sizing work.

This boring bar fits light-duty boring applications in job shop, production, and toolroom environments. Right-hand cutting orientation makes it compatible with standard forward-running spindle setups. The short overall length of 2 inches and small shank diameter keep it at home in gang-tool lathes, Swiss-style turning, and small-bore fixture work. It is sold individually and is appropriate for both CNC programmers setting up first-article runs and manual machinists performing one-off bore sizing jobs.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in small-diameter boring
• TiAlN finish coating extends tool life and reduces heat buildup at the cutting edge
• 0.16-inch minimum bore diameter supports tight, small-bore applications
• 0.50-inch maximum bore depth suited to shallow through and blind bores
• 3/16-inch shank diameter fits standard small-bore toolholders
• Right-hand cutting direction for use with forward-rotating spindles

Compatibility

Designed as an OEM-style replacement or standard tooling addition for small-bore turning and boring applications using toolholders that accept a 3/16-inch round shank.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank firmly in a compatible toolholder and verify overhang is minimized to reduce chatter at small bore diameters. Power down and lock out the machine spindle before changing or adjusting tooling. Confirm bore depth and diameter with gauging before committing to finish passes.
