Value Collection 4121152 Square Polishing Stone 150 Grit

Product Description

The VALUE COLLECTION 4121152 is a square silicon carbide polishing stone designed for fine surface finishing and honing work. Measuring 0.25 inches wide, 0.25 inches thick, and 6 inches in overall length, this stone delivers consistent material removal at a 150 grit rating, classified as Very Fine. Silicon carbide is a hard, fast-cutting abrasive well suited to finishing harder materials, ceramic surfaces, and non-ferrous metals. Machinists, toolmakers, and maintenance technicians use this stone to deburr edges, refine surface finish, and dress tooling. It is not oil-filled, so it can be used dry or with a compatible honing fluid depending on the application.

This polishing stone is suited for bench work and hand honing tasks in machine shops, maintenance facilities, and production environments. The square profile provides flat, consistent contact on flat surfaces, slots, and keyways. At 150 grit Very Fine, it is appropriate for final finishing passes rather than aggressive stock removal. It is typically used after coarser grit operations to refine and smooth a workpiece surface.

Key Features

• 150 grit Very Fine rating for finish honing and light deburring
• Silicon carbide abrasive construction for fast cutting on hard and non-ferrous surfaces
• Square profile maintains flat contact on flat surfaces, slots, and keyways
• 6 inch overall length provides good hand control during bench honing
• Not oil-filled - compatible with dry use or a honing fluid of choice
• Green color for easy grit identification in a multi-stone setup

Compatibility

Designed as a general-purpose hand honing and polishing stone suitable for bench finishing operations on metals, ceramics, and similar hard materials.

Installation Notes

This stone is a handheld abrasive tool used by machinists and maintenance technicians - no power tools or mechanical installation is required. Secure the workpiece firmly before applying the stone to avoid inconsistent contact or injury. When using a honing fluid, select one compatible with the workpiece material to prevent surface contamination. Inspect the stone face for loading or glazing periodically and dress as needed to maintain cutting effectiveness.
