Walmart offers the Dremel EZ Lock Sanding and Grinding Kit, model no. EZ686-01, for $14.99. (Amazon has it for the same price with free shipping for Prime members.) Opt for in-store pickup to avoid the $4.97 shipping fee. That's the lowest price we could find by $5. It includes an EZ Lock mandrel, EZ drum mandrel, six sanding discs, grinding wheel, two grinding stones, six sanding bands, and an abrasive buff.
