The Jooltool™ is a revolutionary compact, multi-functional tool perfect for grinding, sharpening, sanding, deburring, polishing and more. Designed to be the safest sharpening system in the industry, the Jooltool can be used with a variety of attachable discs and brushes.

Particle size for each abrasive disc determines a grade (measurement) of Micron or Grit. Microns are used for medium and fine abrasive grades. Course or highly abrasive products do not equate in particle size to Micron grades, therefore highly abrasive Jooltool products are only measured in Grit. All of the purple disc products and the mini brushes are highly abrasive are stated in Grit.
