Accupro ACC-75-3/8 Boring Grooving Bar Holder

Product Description

The ACCUPRO ACC-75-3/8 is a boring and grooving bar holder designed for use with boring bars in metal cutting and machining applications. It accepts bars with a 3/8 inch inner diameter and seats within a 3/4 inch outer diameter bore. The overall length measures 2-3/4 inches, with a head diameter of 0.88 inches. Featuring two lock-down screws for secure bar retention, this holder belongs to the Series DH line. It is installed by machinists and tool-room technicians working with lathes, boring mills, or CNC turning centers where precise bar positioning and rigid clamping are required.

This bar holder is suited for both production and job-shop environments where boring and grooving operations are performed on metal workpieces. The 3/8 inch ID makes it compatible with standard-shank boring bars of that diameter. The compact head size and 2-3/4 inch overall length allow it to fit in applications with limited clearance. It is a practical choice for shops running small-diameter internal operations that demand repeatable tooling setups.

Installation Notes

Installation is performed by qualified machinists or tool-room personnel. Disengage and lock out the machine before changing or adjusting tooling.
