Accupro ACC-TRG10 Boring Bar 5/8 in Neutral Micrograin

Product Description

The ACCUPRO ACC-TRG10 is a neutral-cutting boring bar designed for internal diameter machining operations on lathes and boring mills. Built from micrograin carbide, it delivers consistent edge retention and dimensional accuracy across a range of materials. The bar accepts a minimum bore diameter of 0.625 inches and reaches a maximum bore depth of 3 inches, making it well-suited for through-holes and blind bores in medium-depth applications. The 5/8-inch shank diameter and 6-inch overall length provide rigidity and reach for production and toolroom environments. The bright finish coating reduces friction and aids chip evacuation during cutting passes.

This boring bar is used in CNC turning centers, manual lathes, and horizontal boring mills where precise internal diameter control is required. It is appropriate for ferrous and non-ferrous workpiece materials in both job-shop and production settings. Machinists and toolroom technicians use this bar for finish boring, semi-finish boring, and light roughing passes where hole quality and repeatability are priorities.

Key Features

• Micrograin carbide construction for extended tool life and sharp edge retention
• Neutral cutting direction for flexible application in standard boring setups
• 0.625-inch minimum bore diameter supports a wide range of hole sizes
• 3-inch maximum bore depth handles medium-reach internal machining
• 5/8-inch shank diameter provides rigid tool holding in standard boring bar holders
• Bright finish coating reduces friction and assists chip flow

Compatibility

Designed as a direct-fit replacement or production boring bar for standard 5/8-inch boring bar holders and tool blocks used on CNC and manual turning equipment.

Installation Notes

Install in a 5/8-inch boring bar holder and confirm the bar is seated to the recommended minimum overhang for the required bore depth to reduce chatter. Secure set screws to the holder manufacturer's specified procedure before cutting. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before changing or adjusting tooling. Follow your facility's tooling change and lockout procedures in accordance with applicable machine safety standards.
