How to Use a Portable Drill for Sanding
A portable hand drill is deigned to hold a drill bit and drill through objects like wood. However, because the chuck of a drill can hold any cylindrical shaft, you can easily use your portable hand drill as a sander. Using a hand drill as a sander allows you to get into tighter places that a traditional orbital sander or belt sander could not reach. However, just like a standard electric sander you must be cautious when using a sander attached to a drill because the sander can cut through the wood quicker than you might think.
Place your hand drill onto a setting between 400 RPM and 600 RPM (revolutions per minute) if your hand drill has a variable speed setting. If not, you cannot adjust the top speed setting and you should skip this step.
Secure the sanding drum arbor into the chuck of your drill. Place the shaft of the arbor as far into your chuck as possible to maximize the gripping potential of your drill's chuck.
Loosen the screw on the top of the drum arbor with a screwdriver. This reduces the size of the arbor so you can place a sanding drum inside.
Slide the sanding drum onto the arbor and tighten the screw to lock the disc onto the arbor.
Pull the trigger on your drill to start the rotation of the sanding drum. If you set the variable speed, you can grip the trigger fully. If not, lightly touch the trigger to ramp the drill up to half speed. As you get comfortable with how the sanding drum sands wood, you can increase the speed. However, resting the drum in one place for an extended period will cause depressions in the wood's surface.
