School of Tools: the Random Orbit Grinder Is a Power Tool Time Machine

Grinding is a do-it-yourself job that everyone does not like, but there is no getting away from it. Use a random sander for your next project and get back the hours and grease you would have spent sanding.

Using sanding blocks and sandpaper can be a tedious and ineffective sanding method. Paper is difficult to use and often is not held. Sanding pads are easier to work with, but require maximum effort. Both of these sanding methods work, but with an eccentric sander you will spend less time sanding and more time enjoying the fruits of your labor.

An arbitrary orbit sander works by simultaneously rotating the grinding disc and moving it in an ellipse. Accidental sanding prevents eddies and grain direction is not a problem when sanding.

Orbital sanders come in either 5 “or 6” sizes depending on the size of the sanding disc used. Five-inch grinders are most popular with DIYers as they are more maneuverable. The pads are round, in contrast to the square ones on the orbital sander . These grinders are controlled by the palm of your hand and all you need is a light touch – let the grinder do the work.

Most of these grinders are equipped with a vacuum system that is activated when the grinder is turned on. Fine wood particles are sucked up through holes on the surface of the sander and placed in a removable container. Even with a vacuum system, it is recommended to wear safety goggles and a respirator mask .

The eccentric sander can be used for all kinds of grinding work. It is capable of tricky jobs like removing paint for more delicate tasks like smoothing corners. When shopping for a sander, spend a little more on better vibration control, better vacuum system, and variable speed.

Prices range from $ 30 for this popular Black & Decker to $ 82 for DeWALT . A box of 50 different sanding discs costs less than $ 20.

The two related grinders include a belt sander, which is designed for sanding long flat surfaces, and an orbital sander (with square sandpaper pads), which is best for finishing jobs as it runs at a lower speed, which gives you more. control.
