Boride Dressing Stones are 6" x 1" x 1" maintenance stones for cleaning, flattening, and resurfacing 6" x 1" Edge Pro form factor sharpening stones. They are used to remove glazing, embedded swarf, and surface irregularities, restoring the cutting performance of the sharpening stone.

These dressing stones are manufactured by Boride Engineered Abrasives using vitrified bond technology and either White Aluminum Oxide or Black Silicon Carbide abrasive. Each version uses a specific Boride bond specification: F9, G9, D10, or K10.

Although Boride originally positions dressing sticks for grinding wheel maintenance, they are also highly effective for conditioning bonded sharpening stones, including resin bond, hybrid bond, metallic bond, vitrified bond, and conventional abrasive stones.

Standard Boride dressing sticks are supplied unmarked from the factory. Gritomatic adds permanent laser engraving with abrasive type, bond, and grit for convenient identification in workshop use.

How to Choose

Do not grit-match dressing stones to sharpening stones. Dressing stones are maintenance tools, not sharpening stones. Their purpose is to clean, open, flatten, and condition the working surface of the sharpening stone. In many cases, a coarser dressing stone is both normal and preferable.

For metallic bond sharpening stones, especially copper-tin bonded diamond stones, use White Aluminum Oxide dressing stones. Silicon Carbide grains may become embedded into soft metallic bond matrices during dressing. White Aluminum Oxide is therefore the safer and recommended choice for metallic bond and most hybrid bond stones.

For resin bond and hybrid bond stones, White Aluminum Oxide is generally the safer universal option. It conditions the stone effectively while reducing the risk of excessive surface damage or unwanted abrasive contamination.

For vitrified and conventional abrasive stones, match the dressing abrasive to the sharpening abrasive family. Use Black Silicon Carbide dressing stones for Silicon Carbide sharpening stones, and White Aluminum Oxide dressing stones for Aluminum Oxide sharpening stones.

More open bonds typically cut faster and clean more aggressively. F9 and D10 variants are generally better for rapid resurfacing, heavy loading, and restoring clogged stones. G9 and K10 variants provide more controlled conditioning and may leave a more uniform surface.

Choosing bond and grit for a dressing stone is not always straightforward. In practice, harder and denser dressing stone bonds may work well across a wider range of sharpening stones, while more open structures tend to maximize cleaning speed and surface aggression.
