Stens Grinding Wheels quickly and efficiently sharpen cutting edges while resisting loss of abrasive material from the wheel itself. The efficiency at which Stens grinding wheels remove metal makes jobs go quicker with less effort. These grinding wheels provide a perfect balance of abrasive materials with binders that work together to provide effective cutting action while helping the wheel keep its shape. The abrasive material used for these wheels is aluminum oxide， one of the most popular choices for grinding and sharpening jobs. Aluminum oxide grains wear so that fresh cutting edges are continually exposed， which helps maintain a consistently renewed grinding surface throughout the life of the wheel. Pink and ruby aluminum oxide abrasive grains provide the added benefit of resisting grooving when resharpen blades. These grinding wheels combine high performance for sharpening blades and cutting edges at a significant value.
