The Black & Decker BDCDS18-QW is a compact sander that you can use anywhere. Thanks to it running on an 18-volt battery, the delta sander has no power cord to take into account. You can easily maneuver the BDCDS18-QW with one hand along the stairs or in hard-to-reach corners. With 12,000 oscillations per minute, that chair or handrail will be smooth in no time. The machine comes with 3 sanding sheets included by default, but if they must be replaced, you can do so in an instant thanks to the Velcro fastening.
