Accupro ACC-62-1/8 Boring Grooving Bar Holder Series Dh

Product Description

The ACCUPRO ACC-62-1/8 is a boring grooving bar holder designed for use with indexable boring and grooving bar systems in metalworking and machining operations. It features a 1/8 inch inner diameter (ID) and a 5/8 inch outer diameter (OD), with an overall length (OAL) of 2-3/4 inches and a head diameter of 3/4 inches. The holder is secured with two lock-down screws, providing rigid clamping to minimize vibration and maintain positional accuracy during internal grooving and boring passes. This is a Series DH holder, and it is typically installed by machinists and toolroom professionals working with CNC lathes and manual turning equipment.

This holder is suited for internal grooving and boring applications on CNC lathes, turret lathes, and manual turning centers where compact tooling footprint is required. The 1/8 inch ID makes it appropriate for small-bore work where clearance and rigidity in confined diameters are priorities. It ships as a single unit and is a direct add to existing Series DH tooling setups. Machinists working on precision internal profiles, snap ring grooves, or undercut features in small-bore components will find this a direct-fit solution within a compatible Series DH system.

Key Features

• 1/8 inch ID and 5/8 inch OD for small-bore grooving and boring applications
• 2-3/4 inch overall length (OAL) for compact tool reach in confined bores
• 3/4 inch head diameter for consistent seating and radial support
• Two lock-down screws provide secure, repeatable bar clamping
• Series DH designation for compatibility with matching Series DH boring bar systems
• Lightweight at 0.21875 pounds, reducing tool turret load

Compatibility

Designed as an OEM-style replacement and standard tooling component for Series DH boring and grooving bar holder systems used in CNC and manual turning applications.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Before mounting or changing tooling, ensure the machine spindle is fully stopped and the control is placed in an appropriate lockout state per shop safety procedures. Tighten both lock-down screws evenly to secure the boring bar without inducing deflection. Verify bar runout and overhang after mounting to confirm alignment before taking a test cut.
