4 1/4 x 4 x 3/4吋 鑰匙拋光不織布輪

I was surprised how well this wheel cleaned up the key edges without gouging the metal. The 4-inch size fit perfectly on my bench grinder, and the non-woven material left a consistent satin finish.

I needed something aggressive enough to clean up a brass keyway without scratching the metal, and this 4 1/4 inch wheel delivered perfectly on the medium grit setting. The 3/4 inch thickness gives it great stability on the arbor, and it holds up well under moderate pressure without glazing over.

The fine grit option took the sharp edge off freshly cut keys without loading up the wheel, and it works great on the bench grinder for a quick satin finish.
