Tru-maxx 69405199M Boat Polishing Stone 120 Grit 9 Inches

Product Description

The TRU-MAXX 69405199M is a boat-shaped aluminum oxide polishing stone designed for fine-grit material finishing work. At 120 grit and a fine grade, it removes light burrs, smooths surfaces, and refines edges on metal and other hard materials. The stone measures 9 inches in overall length and weighs 1 pound. It is not oil-filled, making it ready to use dry or with a compatible honing fluid depending on the application. Machinists, toolroom technicians, and maintenance professionals use this type of stone for bench work, die finishing, and precision surface preparation tasks.

This polishing stone suits applications where a boat profile is needed to access contoured surfaces, slots, grooves, and tight radii that flat or rectangular stones cannot reach. The aluminum oxide abrasive is appropriate for use on ferrous metals, alloy steels, and hard tool materials. At 9 inches in length, it provides enough working surface for both hand-held and fixture-assisted finishing. It is well suited to production shops, toolrooms, and maintenance facilities where consistent fine finishing is required.

Compatibility

Designed as a general-purpose hand finishing stone for use in toolroom, bench, and production maintenance applications requiring a fine-grit boat-profile abrasive.

Installation Notes

No power tools or mechanical installation is required for this hand stone. Secure the workpiece firmly before beginning any finishing pass. When using a honing fluid, apply sparingly and keep the work area clear of slip hazards. Follow your facility or shop safety protocols for abrasive tool handling and personal protective equipment.
