Accupro ACC-62-1/4 Boring Grooving Bar Holder Series Dh

Product Description

The ACCUPRO ACC-62-1/4 is a boring and grooving bar holder designed for precision metal cutting operations on lathes and boring machines. It accepts a 5/8 inch outside diameter boring bar and fits into a 14 inch inside diameter tool holder seat. The overall assembly length is 2-3/4 inches with a 3/4 inch head diameter. Two lock-down screws secure the boring bar firmly in place, reducing vibration and maintaining consistent tool position during interrupted or continuous cuts. Machinists and toolroom technicians install this holder when setting up internal diameter turning, grooving, or profiling operations. The holder is part of the Series DH line and weighs 0.219 pounds.

This bar holder is suited for use in machine shops, toolrooms, and production environments where boring and grooving operations require a rigid, repeatable tool setup. It is compatible with 5/8 inch shank boring bars commonly used for internal turning and grooving on manual and CNC lathes. The compact overall length of 2-3/4 inches makes it practical for setups where clearance inside the workpiece or turret is limited. It ships as a single unit.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing the boring bar or adjusting the lock-down screws. Use the appropriate hex key or Allen wrench to tighten both lock-down screws evenly to avoid canting the bar in the holder. Verify bar overhang and tool height alignment before resuming cutting operations.
