SELECTING PROPER SPEEDS
Different speeds are required depending upon the type of operation being performed. The following chart

5 to MAX
Sanding Wood
5 to MAX
Cutting Hard Metal
5 to MAX
Engraving Metal
4 to 5
De-burring
4 to 5
Drilling Holes
4 to 5
Removing Rust
3 to 4
Sharpening
3 to 4
Polishing
1 to 2
HIGH SPEED USE
Higher speeds are better for carving, routing shaping or cutting wood. Hardwoods, metals and glass
require high-speed operation. Drilling should also be performed at high-speeds.
NOTE: Incoming voltage greatly affects the speed of the tool. Speed will drop in relation to a decrease in
voltage. If your tool appears to be running slowly, simply increase the speed setting accordingly.
LOW SPEED USE
Certain materials (some plastics, for example) require a relatively slow speed because at high speed
the friction of the tool generates heat and causes the plastic to melt. Slow speeds are usually best for
polishing operations with felt polishing accessories. They may also be best for working on such delicate
projects as delicate woodcarving and fragile model parts.
