Operating Speeds

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.

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. The tool may not start at switch position #1 in those areas where outlet voltage is less than 120 volts. Simply move the switch lever to a higher position to begin operation.

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 page 24, 25, and 26 to determine the proper speed, based on the material being worked and the type of accessory being used. These charts enable you to select both the correct accessory and the optimum speed at a glance.

Needs for Slower Speeds

Certain materials, however, (some plastics and precious metals, for example) require a relatively slow speed because at high speed the friction of the accessory generates heat and may cause damage to the material.

Slow 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.) No greater than speed setting 4 for the model F013039519.

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

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

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