An Overview On Rotary Tool Kits

What’s a tool that is commonly used by hobbyists, woodworkers, construction workers and even plumbers with equal frequency? There aren’t many, that’s for sure. But aside from the old reliable hammer, a handheld rotary tool is one of the most versatile items in any tool belt, no matter who’s wearing it.

What is a rotary tool? These days, they can come in any number of shapes and sizes, most of which are handheld and roughly cylindrical. But the real defining factor is the motor. As the name implies, the tip moves in a rotary motion, spinning at high speeds with a lot of torque behind it. This is distinct from the motor inside oscillating multi-tools, which may look very similar to rotary tools and in fact can be used for many of the same type of jobs. But oscillating motors work in a super-fast side-to-side motion. That makes them better suited to handle straight cuts and more heavy duty jobs such as tile work.

A rotary tool’s strengths primarily lie in versatility and fine detail work. That makes them great for sanding, carving, etching and even sharpening knives, and that’s just scratching the surface.

Of course, you’ll need the right attachments to match the job. Individual tools can vary, but most rotary tool kits will come with a variety of accessories to suit specific tasks, with some possible extension attachments for hard-to-reach areas or angled cuts. These accessories can be changed out with some sort of chuck or locking mechanism. For artisans or woodworkers who change out attachments regularly, a quick-change system is especially key.

Among the most common attachments you’ll need are an assortment of cutting wheels, which can cut precise circles into wood or even metal. Sanding pads are used for sanding down woodwork, and will come in various grades of coarseness. Carbide bits are used for carving and etching, while wire wheels will take dust off of sensitive metals. Again, there are hundreds of accessories to suit almost any application. To boost the usefulness of your rotary tool, check to see that it can accept accessories from third party manufacturers. It will make shopping for the right bits and wheels much easier.

In general, you’ll find two different types of rotary tools: Cordless or corded. Cordless models work on a rechargeable battery, which allows you the freedom to move around at will — for as long as the battery lasts. Corded models have less range, of course, but they do tend to be lighter and easier to handle without a lithium battery weighing them down.

Power is generally measured in amps for corded models and volts for cordless rotary tools. That will give you a good way to compare the maximum push you’ll have behind those drills and saws, and also how quickly those cordless batteries may be likely to run out.

Speed is measured in RPM, or rotations per minute. A good rotary tool should have setting that can be adjusted up to that maximum number, since you won’t want super-high speeds for most jobs. Bear in mind that most manufacturers measure RPM when the tool is spinning freely and without resistance, so power is a factor here for practical purposes.

The Rotary Tool Kit Buying Guide

  • Plan on cutting through metal? Most rotary tools are up to the task, but you may want to take precautions to protect your accessories. Proper application of a little cutting oil will go a long way when you’re using carbide-metal wheels or saws. The same goes for buffing or polishing jobs. Just use wax or polish before hitting those sensitive surfaces, and make sure you keep the speed on medium or below.
  • Rotary tools can be an effective way to sharpen your knives, and many kits have attachments specifically suited to the job. Safety first, though: Make sure the rotation turns away from you, as sparks can be expected to fly.
