Robo-Sander Flush Trim Sanding Drums
Robo-Sander’s simple but ingenious enhancement of the drum sander turns your drill press into a duplicating machine. A phenolic wheel on the drum serves as a flush guide which follows your template or original piece, while the drum sands an oversize duplicate to an exact match. Complex curves & end grain can be shaped accurately without tear-out or chatter.
Shank size is 3/8 inch.
Extra sanding sleeves available separately.
