With a wide range of accessories and attachments, this is one of the most versatile power tool you can have in your toolbox.

The early version of the tool was developed by Albert J. Dremel, the founder of the Dremel Company, back in 1932. Over the years, the Dremel rotary tool has turned into a compact powerhouse and become a favorite among craftsmen, DIY enthusiasts & hobbyists alike, transforming and shaping the way we approach a myriad of projects. While it is not a tough tool, I find it extremely useful for a number of different tasks.

Which Model Should You Choose?

Consider the following factors when you want to pick the right model:

  • Speed: Models with higher speed and variable speed options offer versatility. Faster speeds work well for tasks like polishing metals, cutting wood, or grinding hard materials. Lower speeds are better for more delicate tasks like engraving or working with plastic.
  • Torque: More torque results in more powerful cutting and grinding, which is essential for tasks involving harder materials such as metals, harder woods, or masonry.
  • Clamping system: Check the system used for attaching the accessories to the tool spindle. A universal 3-jaw chuck, for example, allows for easy and quick accessory changes without needing collets.
  • Power: More power allows you to handle tougher materials and more demanding projects. If you’re planning to work with hardwoods, metals, or other resilient materials, opt for a more powerful corded model.

Once you’ve chosen your Dremel, buy a kit containing the accessories and attachments for the types of projects you want to do.

Dremel Accessories

Dremel Accessories & attachments
Accessories are tool bits such as cutting discs, grinding wheels, sanding bands, polishing bits, etc.
While I am not aware of an official color-coding system, I noticed that Dremel uses different colors to group the accessories and attachments by function:

Cyan (Engraving/Carving) Covers high-speed cutters for carving, shaping, hollowing, grooving, slotting, and making tapered holes, diamond wheel points for fine detailing, and engraving cutters for etching and marking.
Yellow (Polishing/Cleaning) Includes buffing wheels, points, brushes, and polishing compounds for metals and plastics.
Green (Grinding) Comprises grinding and sharpening stones, silicon carbide grinding stones for tough materials like masonry and porcelain, and aluminum oxide grinding stones for metals, castings, welded joints, and more
Red (Cutting) Incorporates cutting wheels for wood, metal, plexiglass, and plastic, including reinforced cut-off wheels for added durability and spiral cutting bits for intricate cuts in wood.
Purple (Sanding) Features a variety of sanding drums, bands, discs, flap wheels for detailed work, and abrasive buffs for removing rust and polishing metal.

See our guide on Dremel bits for a detailed explanation with pictures.


In addition to the standard accessories listed above, there are also optional attachments like:

  • Flex Shaft: This attachment is perfect for precision work, as it provides a flexible, 36-inch shaft that allows for more precise detailing and control. Ideal for tasks like carving, engraving, or intricate sanding. You could even use it as a nail Dremel.
  • Router Attachment: Dremel offers both plunger router attachment and router table attachment to turn your Dremel into a wood router.
  • Multipurpose Cutting Kit: This attachment allows you to make cuts in a variety of materials from any angle and provides a template for cutting shapes.

How to Use a Dremel?

  1. Start by selecting the right Dremel bit according to the type of work and workpiece material.
  2. To use an accessory, loosen the chuck, insert the attachment shaft, and tighten the chuck while holding the shaft lock button. A more detailed explanation with pictures on changing Dremel bits can be found here.
  3. Connect the power cord, or in the case of cordless models, attach the battery.
  4. Set the speed according to the operation and recommended speed range of bit.
  5. Slowly bring the spinning tool bit onto the workpiece and move the Dremel tool at a steady and constant motion.
  6. Do not force the tool into your workpiece. Doing so could damage your work as well as the tool.
  7. When working with hard materials such as cutting glass or tiles, dip the tool bit in a bowl of water to dissipate the heat. Also, consider getting a Dremel Multi-Vise for holding the workpiece.


Safety first! With any power tools, safety should be your primary concern. Here are some essential tips and best practices for using a Dremel safely.

  • Protective Gear: Always wear wrap-around safety glasses, a dust mask, and gloves to prevent injury from flying debris.
  • Work Area: Ensure your workspace is well-lit and ventilated. Keep your work area clean and uncluttered to avoid accidents.
  • Clothing and Jewelry: Avoid loose clothing or jewelry that could potentially get caught in the tool.
  • Tool Handling: Never force the tool into your workpiece, which could lead to tool damage or injury. Let the speed of the tool do the work.
  • Power: Always unplug the tool when not in use or when changing attachments. Be aware of where the power cord is at all times to prevent accidents.

Maintenance and Care

Proper maintenance of your Dremel tool will ensure its longevity and optimal performance.

Regularly check the carbon brushes for wear and replace them when necessary. Lubricate the motor shaft every 20 hours of use with lightweight machine oil or air tool oil to maintain smooth operation.

Keep the tool clean, removing dust and debris from vents and the motor housing to prevent overheating.
