Heavy-duty rotary tools are:

  • Also known as cutout tools or spiral saws
  • Intended for professional tasks

Rotary Tool Power, Size and Features

Rotary tools are powered by an electric motor, compressed motor or gasoline engine. And the materials they can be used on -- wood, metal, ceramic and plastic surfaces – vary as widely as the tool’s speed and features.

Power

Rotary tools are available in both corded and cordless models. Cordless tools offer portability, but corded tools have an unlimited power supply and are often lightweight.

  • Higher power usually results in more weight and larger body.
  • Power ratings range from 1 to 5.5 amps for corded models, and 4.8 volts to 18 volts for cordless models.
  • Consider a higher voltage model if you work with your rotary tool for long periods.


Speed and Bit Size

A rotary tool can range in speed from 5,000 to 15,000 rpm (cordless) or 5,000 to 35,000 rpm (corded).

  • Wider speed range and more settings will make your rotary tool more versatile.
  • The collet or chuck determines the size of the bit shank that your rotary can accept.
  • A collet/chuck can be adapted to hold smaller bit shanks, but it cannot be adapted to hold larger ones.


Attachments

  • Attachments are usually intended for use only on certain brands or models.
  • Bits are often interchangeable as long as they’re the right shank size.
  • Specialized rotary tools have few accessories and attachments.
  • A flex shaft delivers control and maneuverability for fine detail work.


Features

  • Easy bit change: Tool systems that are easy to operate bit changes.
  • Comfortable grip: Maximize maneuverability, control and comfort during use.
  • Replaceable motor brushes: Extends the life of the tool and protects the motor by allowing you to change the brushes when they’re worn.
