Tru-maxx 69405306M Boat Polishing Stone 120 Grit Fine

Product Description

The TRU-MAXX 69405306M is a boat-shaped polishing stone made from aluminum oxide abrasive, designed for fine deburring, honing, and surface finishing of metal parts and tooling. At 9 inches overall length and a 120-grit fine grade, this stone delivers consistent stock removal on workpieces where a smooth, refined surface finish is required. The boat profile allows access to contoured surfaces, grooves, and hard-to-reach areas that flat stones cannot address. It is not oil-filled, so no conditioning is required before use. Machinists, tool-and-die workers, and maintenance technicians keep this stone on hand for bench work and in-place component finishing.

This polishing stone is suited for precision hand-finishing applications across metalworking, tool maintenance, and machine shop environments. The 120-grit fine grade makes it appropriate as a finishing step after coarser stock removal, leaving a smooth surface on dies, molds, punches, and similar components. The Holey Pink color is standard for this aluminum oxide formulation. It is a dry-use stone that does not require oil or fluid during operation.

Key Features

• Boat shape provides access to contoured surfaces, channels, and irregular profiles
• Aluminum oxide abrasive delivers consistent cutting action on ferrous and non-ferrous metals
• 120 grit fine grade suited for finish honing after rough stock removal
• 9 inches overall length offers good reach for bench and in-place work
• Non-oil-filled construction requires no pre-conditioning or fluid during use
• Holey Pink aluminum oxide formulation standard for fine-grade bench stones

Compatibility

Designed as a general-purpose fine-grade honing and polishing stone for metalworking bench operations, tool-and-die work, and maintenance applications requiring a boat-profile abrasive.

Installation Notes

This stone is a hand tool used at the bench or on stationary workpieces and does not require mounting or power-down procedures in the same manner as mechanical components. Secure the workpiece firmly before applying the stone to prevent movement during finishing. Use appropriate eye protection and work gloves when performing hand-honing operations. Inspect the stone for cracks or chips before each use and replace if structural integrity is compromised.
