Accupro ACC-TRG6 Boring Bar Neutral Micrograin 3/8 in

Product Description

The ACCUPRO ACC-TRG6 is a neutral-cutting boring bar designed for precision internal turning and boring operations on manual and CNC lathes. Built from micrograin carbide, this bar delivers consistent cutting performance in ferrous and non-ferrous materials. It accepts a 0.375-inch shank diameter and achieves a minimum bore diameter of 0.375 inches with a maximum bore depth of 1.75 inches. The bright finish coating reduces built-up edge and supports clean chip evacuation. Machinists and toolroom technicians use this bar when tight bore tolerances are required on small-diameter workpieces.

The ACC-TRG6 is suited for light to medium boring passes in a lathe or boring machine setup. Its neutral cutting direction makes it appropriate for straight boring without a directional bias, which simplifies tool setup in both left-hand and right-hand spindle configurations. The 3.5-inch overall length provides adequate clearance for most standard tool holders while keeping overhang minimal. This bar is a single-piece unit packaged individually.

Key Features

• Micrograin carbide construction for wear resistance and edge retention
• Neutral cutting direction for versatile spindle compatibility
• Minimum bore diameter of 0.375 inches for small-bore applications
• Maximum bore depth of 1.75 inches
• Bright finish coating reduces friction and built-up edge
• Compact 3.5-inch overall length minimizes overhang and chatter

Compatibility

Designed as an OEM-style replacement or direct tooling addition for lathes and boring machines that accept 0.375-inch shank boring bars.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully in the tool holder to the recommended grip length before initiating a cut. Power down and lock out the machine spindle before changing or adjusting the boring bar. Do not exceed the recommended depth of cut for the workpiece material to avoid deflection or tool breakage.
