Walmart offers the Dremel 110-Piece Super Accessory Kit, model no. 709-02, for $18.98. (Amazon has the same for Prime members.) Opt for in-store pickup to dodge the $4.97 shipping fee. That's the lowest price we could find by $8, although it was $5 less in December. The kit includes grinding stones, a dressing stone, felt polishing wheels, mandrels, cut off wheels, polishing compound, sanding bands, sandpaper discs, wrench and reusable carrying case.
