S_ow speeds (15,000 RPM or less) usually are best for polishing operations employing the felt polishing accessories. They may also be best for working on delicate projects as "eggery" work. delicate wood carving and fragile model parts. All brushing applications require lower

speeds to avoid wire discharge from the holder.

Higher speeds are better for carving, cutting, routing, shaping, cutting dadoes or rabbets in wood.

practice piece of material. Vary'speed to find

the best speed for the accessory you are using and the job to be done.

NOTE: Speed is affected by voltage changes. A reduced incoming voltage will slow the RPM of the tool, especially at the lowest setting. If your tool appears to be running slowly increase the speed setting accordingly.

There are three basic types of Rotary Tools:

single speed, two-speed and variable speed models.

•Single speed has one ON-OFF switch, When the switch is on, the toot runs at 35,000 RPM.

•On the two-speed-model, there is a LO and HI switch. When the switch indicator is on

the low setting, the tool runs at about 15,000 RPM. When the switch indicator is on the

high setting, the tool runs at about 35,000 RPM.

•On the variable speed model, there are switch setting indicators marked with a line. Slide to the number on the housing to select the operating speed needed from 5,000 - 35,000 RPM.

You can refer to the charts on pages ?6 & 27' to determine the proper speea, based on the material being worked and the t_!_e o; t':_tb_ro:_ other accessory being used. These charts enable you to select both the correct acces- sory and the optimum speed at a glance.

If you have a single-speed or two-sF-ee'd model, you will be able to use many accessories to do a wide assortment of jobs. For the majority of applications, all models of the Rotary Tool should be used at top speed.

NEEDS FOR SLOWER SPEEDS

Certain materials, however, (some plastics, for example) require a relatively slow speed because at high speed the friction of the accessory generates heat and causes the ' plastic to melt.

Hardwoods, metals and glass require high speed operation, and drilling should also be done at high speeds.

The speed of the Rotary Tool is controlled by setting this indicator on the housing.

The point to remem.ber is this: You can do the

great majority of work with the single speed at its regular speed of 35.000 RPM. But for

certain materials and types of work, you need slower speeds -- which is the reason the variable speed models were developed.

To aid you in determining the optimum operational speed for different materials and different accessories, we have constructed table that appears on pages 26 & 27. By referring to this table, you can determine the recommended speeds for each type of
