The Rotary Tool operates at speeds up to 30,000 revolutions per minute The typical electdc drill is a low- speed, high torque too!; the Rotary Tool is ust the opposite -a high-speed, low torque tool The chief difference to the user is that in the high speed tools, the speed combined with the accessory mounted in the collet does the work. You don't appty pressure to the tool, but simply hold and gu{de it tn the low speed tools, you not only guide the tool, but also apply pressure to it, as you do, for example, when drilling a hole It is this high speed, along with its compact size and wide variety of special accessories, that makes the Rotary Tool different from other power tools The speed enables it to do jobs low speed tools cannot do, such as culling hardened steel, engraving gtass, etc Getting the most out of your Rotary Tool is a ma_ter of learning how to let this speed work for you Using the Rotary Power TooN Read the next sections carefully They will hetp you use your Rotary Tool correctly and hetp you select the correct accessory for your job .... The first step in learning to use the Rotary Tool is to get the "feel" of it Hold it in your hand and feel its weight and balance. Feel the taper of the housing This taper permits the Rotary Tool to be grasped much like a pen or pencil When you turn on the tool for the first time, hold it away from your face. Accessories can be damaged during handling, and can fly apart as they come up to speed This is net common, but it does happen Practice on scrap materials first to see how the Rotary Tool cuts Keep in mind that the work is done by the speed of the tool and by the accessory in the coltet. You should not tean on or push the tool into the work Instead, lower the spinning accessorylightly to the work and allow it to touch the point at which you want cutting (or sanding or etching, etc ) to begin, Concentrate on guiding the tool over the work using very little pressure from your hand Aitow the accessory to do the work Usually, it is best to make a series of passes with the tool rather than attempt to do alt the work in one pass To make a cut, for example, pass the tool back and forth over the work, much as you would a small paint brush Cut a little material on each pass until you reach the desired depth, For most work, the deft, gentle touch is best With it, you have the best control, are less likely to make errors, and will get the most efficient work out of the accessory For best control in close work, grip the Rotary Tool fike a pencil between your thumb and forefinge_ This is the "handgrip" method of holding the tool used for operationssuch as grinding a flat surface or using cutoff wheels _ When using the steel saws, cutoff wheels, high speed cutters or tungsten carbide cutters, always have the work securely clamped. Never attempt to hold the work with one hand while using any of these accessories. The reason is that these wheels will grab if they become slightly canted in the groove, and can kickback causing loss of control resulting in serious injury. Your second hand should be used to steady and guide the hand holding the tool. When a cutoff wheel grabs, the wheel itself usually breaks. When the steel saw, high speed cutters or tungsten carbide cutter grab, it may jump from the groove and you could lose control of the tool. Page 4 Operating Speeds & Accessories Set the speed indicator to fit the job; to achieve the best job results when working with different materials, the speed of the Rotary Too_ should be regulated. Only a full wave output speed control such as the Sears Model 2514 (available from catalog only) shoutd be used with the Modet 572.610520 Models 572610530 & 572610720 Rotary Tools have an integral speed control and an external speed control should never be used with these tools To select the right speed for each job, use a practice piece of material. Vary speed to find the best speed for the accessory you are using and the job to be done There are three basic types of Rotary Tools: singte speed, two-speed and variable speed models On the single speed model, there is an ON-OFF switch_ When the switch is on, the toot runs at 28,000 RPM On the twospeed- mode!, there is a LO and H! switch When the switch indicator is on the low setting, the too] runs at about 20,000 RPM When the switch indicator is on the high setting, the toot runs at about 30,000 RPM On the variable speed model, there is a switch indicator with a white line on it..Slide to the number on the housing to seiect the operating speed needed from 5,000 -30,000 RPM You can refer to the charts on page 5 to determine the proper speed, based on the material being worked and the type of cutter or other accessory being used These charts enable you to select both the correct accessory and the optimum speed at a glance If you have a single-speed or two-speed model, you will be able to use many accessories to do a wide assortment of jobs. For the majority of applications, all models of ...
