Value Collection 4053402 Round Polishing Stone 400 Grit

Product Description

The VALUE COLLECTION 4053402 is a round aluminum oxide polishing stone designed for precision deburring, honing, and surface finishing of metal and other hard materials. At 6 inches in overall length and 1/4 inch in diameter, this slender stone fits into tight grooves, bores, and contoured surfaces where flat stones cannot reach. It carries a 400 grit rating, placing it in the medium grade range and making it suitable for light stock removal and intermediate finishing work. The stone is not oil-filled, so it can be used dry or with a compatible honing oil depending on the application. Machinists, tool-and-die workers, and maintenance technicians are the primary users of this type of stone.

This polishing stone is well suited for bench work and hand-finishing applications in manufacturing, maintenance, and fabrication environments. The round profile makes it effective for polishing the interior walls of drilled holes, radius slots, and cylindrical recesses. At 400 grit medium grade, it leaves a consistent, moderately fine finish appropriate for parts that will see further polishing or that require a clean but not mirror-polished surface. The 6-inch length provides adequate grip and control during manual strokes. This stone is sold in a package quantity of 6 units per order.

Compatibility

Designed as a general-purpose hand polishing stone for use on metal workpieces in bench finishing, deburring, and honing applications where a round profile and medium grit are required.

Installation Notes

This stone is a hand-held finishing tool and does not require mechanical installation. Secure the workpiece in a vise or fixture before use to maintain control and consistent stroke pressure. If using with honing oil, apply a light coat to the stone surface before working to extend abrasive life and reduce loading. Inspect the stone for cracks or chips before each use and discard any damaged stones to avoid inconsistent surface results.
