Product Description

Product Description

Add the finishing details to your project, smooth rough surfaces, refine edges, and more with BLACK+DECKER’s Dragster 7.0 Amp electric belt sander. The 7.0 Amp motor delivers plenty of power to get the job done, and thanks to the belt sander’s corded design, you’ll have unlimited runtime for longer tasks. This electric sander is angled for precision sanding of adjoining surfaces, while the flush, low-profile design expands functionality even on vertical surfaces. Plus, the retractable hood exposes the top of the sanding belt for added functionality in tight spaces. An adjustable, 3-position handle keeps you comfortable, while an easy-to-empty dust bag catches particles and keeps your worksurface cleaner.

Amazon.com

Featuring an innovative front roller that allows you to reach even the tightest corners with ease and cuts down on the need for flush sanding, this 6.0 Amp sander from Black & Decker is ideal for home improvement enthusiasts. Compact and lightweight, the Dragster DS321 boasts a retractable, three-position handle for optimum control and a dust collector to keep your work area clean for improved visibility. When it's time to change the paper, simply utilize the belt release lever and adjustment knob (which ensures the belt remains in the correct position) and you're ready to get back to work.

Worked flawless.... after small learning curve.
So first off. I've never used a belt sander before. In the pics this is a 30+ year old bench built by my grandfather. Just sitting on it and you got seven splinters. I decided to take apart, rebuild, and stain. So for the first run... belt was flying all over the place. Complete fail. However! You have to take time. Read instructions. Turn unit over, set, and adjust the dial. The dial adjustments are actually quite small. A quarter inch turn, turned out perfect. It is very important to get this set FIRST! After figuring this out was flawless. Ran like a champ. Removed dust bag as this volume of dust was ridiculous. Overall best idea ever, super affordable, and worked like a dream. Highly recommended. Just take the time and learn how to adjust the lock the belt.Cheers and good luck!
