Guidelines for Choosing the Right Rotary Tool Kits
Applications, power, speed and drill size
The rotary tools are designed to provide precision and high performance. The rotary tools are simple enough to be used by inexperienced people and in turn meet the needs of professional users. They are ideal for applications at home and at work, there are also different types of accessories to get the most out of the tool.
Essentially, all rotary tools do the same: rotate, but logically their differences exist. Professional rotary tools are high strength rotary tools, sometimes marketed as cutting tools or spiral saws, are more powerful and intended for professional tasks, such as making cuts in drywall, electrical boxes, and other accessories.
They tend to be a little bigger, heavier and usually do not include accessories and complements. They are suitable for the most demanding applications. Light rotary tools are smaller, perfect for crafts, carpentry, and jobs that require fine detail. They tend to be the preferred option for most of those who prefer to do things for themselves and for home users.
What type of power rotary tools?
Rotary tools exist with both cable and battery. If we do not need to transport it or if we plan to use our tool for long periods of time it is advisable to choose a model with cable, which is also usually cheaper.
The tools with cable offer the advantage of having an unlimited power supply, in addition to being usually lighter because they do not need to charge their own built-in power source.
For both models, both with cable and battery, generally greater power will represent the greater weight and greater size, while with light tools we will have less power but gain in comfort, maneuverability, and control. Nominal powers range from 1 to 5.5 amps for wired models and 4.8 V to 18 V for wireless models.
Speed and size of drill bit
A rotary tool can vary the speed from 5,000 to 15,000 rpm (without cable) or from 5,000 to 35,000 rpm (with cable). A wider speed ranges and higher speed settings will make the rotary tool more versatile.
The tool holder or mandrel are two things, which determine the drill size that your press can accept. A large nozzle/mandrel size increases the versatility of the tool because most can be adapted to hold smaller bits, but cannot be adapted for larger ones.
Most rotary tools can accommodate 1/8 inch or 1/4 inch, although other sizes are available. 1/4 inch offers a wider selection of drill bits, as it can usually be adapted to 1/8 inch.
Many users will appreciate a 1/4 inch capacity for interchangeability with other tools. Accessories are often interchangeable for more versatile use. Specialized rotary tools have few accessories and attachments. A flexible shaft provides maneuverability and control for fine detail work.
