Magnahone diamond coated hone, allows you to precisely hone the inner diameter of magnets. Works for Rare Earth (Cobalt), and Ceramic type magnets.
For best results do not cut over .005 per cut or use. If greater amount is needed use more stepped sizes to achieve best results for motor and longer hone life. Cutting more out decreases accuracy and life of hone.
We try to keep in stock the most common sizes, other sizes are available usually within a few days.
