Walmart offers the Wen 101-Piece Rotary Tool Kit, model no. 2307, for $15.26. (Amazon and Home Depot have it for the same price.) Opt for in-store pickup to avoid the $4.97 shipping charge. That's the lowest price we could find by $2, although in June we saw it for $3 less. This kit includes the 1-amp rotary tool with seven speed settings, 54 sanding discs, 20 cutoff wheels, 10 grinding stones, four sander bands, two drill bits, two mandrels, two high-speed cutters, two felt polishing wheels, two collets, drum sander, and dressing stone.
