The Dremel Stylus package contains an ergonomically shaped Rotary Tool, a recharger which doubles as a stand, and a set of bits. The tool has a standard collet. Different size collets (1/32" to 1/8") can hold tips with various size shafts. All of the switches and controls are within easy reach. The Power Button has a slight delay built in to prevent accidental starts. The switch below the power button is the Shaft Lock...for when the collet needs to be changed.
The Stylus can rotate between 5,000 and 25,000 RPM, controlled by the speed dial at the rear. The variable speed allows for the proper RPM for the specific material and task at hand.
Ventilation for the tool is on the side. There is a rubber grip section molded for the thumb and forefinger. However, there are many ways of gripping the Stylus besides the obvious "pencil grip." The handle can be rested on a surface for added stability or gripped upside down for getting closer to the work.
The lithium-ion battery is housed in the handle. The contacts automatically align themselves when the tool is placed in the holder. A green light indicates recharging. The light will go off when the tool has been fully charged.
Rotation tools work not by how hard one can press on the work, but by using the correct bit. If the expected result is not being achieved, then either adjust the speed or adjust the tip. The Dremel Stylus came with a good set of bits, discs, and polisher tips.
BTW, all of the tips from the XPR 400 will also fit the Stylus...which is GREAT because we have a lot of different tips from the XPR!
