Getting Started

Congratulations and welcome to the exciting world of Dremel versatile tool systems. Learn the basic concepts, terminology and operation of Dremel tools, attachments and accessories, as well as gain insight into the almost endless list of uses for our tools.


What is a Rotary tool?

Rotary tools are hand-held power tools that use high-speed and low torque to undertake a variety of useful tasks with control and precision. Since AJ Dremel invented the first rotary tool over 75 years ago, no other brand has worked harder to bring users a more complete and innovative system of rotary tools, accessories and attachments. Over the years Dremel rotary tools have become the gold standard in versatility, performance, and quality by which all other rotary tools are judged.

What Is an Oscillating Tool?

Oscillating tools like rotary tools use a variety of accessories to accomplish a wide range of DIY tasks for repair, remodeling and restoration. However, rather than spin like a rotary tool, oscillating tools use rapid side- to-side motion to cut, scrape, sand, remove grout, grind and more. You can rest assured that a Dremel oscillating tool will help you get the job done with superior versatility, durability, and control.

What Is a Trio™ tool?

The Dremel Trio allows users to cut, sand, and rout using one multi-purpose tool. Featuring a system of accessories and attachments to increase versatility, Trio users can cut multiple materials including wood, plastic, drywall, sheet metal, wall tile and more without switching tools. The tool’s unique, 360-degree cutting technology and plunge-cut ability allows users to make quick and controlled cuts, while its unique, 90-degree pivoting handle facilitates added comfort, control, and accuracy.


The Collet

A collet is the most precise way to hold an accessory (bit) in a high speed rotary tool or the Dremel Trio. The collet is located underneath the collet nut, inserted in the end of the tool’s shaft.

Rotary tool collet

There are 4 different sized collets available to accommodate different accessory shank sizes from 1/8 inch down to 1/32 inch. It is essential to use the correct sized collet for each accessory. The collets are marked with corresponding shank size: no rings – 1/8 inch (480), 1 ring – 1/32 inch (483), 2 rings – 1/16 inch (482), 3 rings – 3/32 inch (481).

Dremel Trio™ collet

The Dremel Trio tool uses a 3/16” collet for all Trio accessories. Trio accessories are exclusive to the Dremel Trio tool system and are not interchangeable with Dremel rotary tools. See your owner's manual for more detailed information on collets.

Dremel Multi-Max™ clamping screw

The Dremel Multi-Max oscillating tool uses a clamping screw and a washer to secure accessories onto the tool. A Hex Key wrench is used to loosen and tighten the clamping screw when installing and removing accessories.



This grip offers the best control for fine detail work.


Use this grip with cutters when making longer, smoother cuts. This grip offers good control for cutting depth.


One and two hands. When you want to keep the tool parallel to the work surface for sanding or grinding, use the one-handed grip. Use the two-handed grip every time you use a cut-off wheel. Cut-off wheels can stick and cause kickback. Two hands offer better control.
