The Dremel® 3100 is the result of upgrading our most popular rotary tool using user-requested features to improve the tool's design and ergonomics. The tool also features the EZ Twist™ nose cap with an integrated wrench that allows the nose cap to be used as a wrench to tighten accessories and eliminates the need for a separate wrench. A more efficient fan design and side vents provide a cooler running tool making it comfortable for extended periods of use. The tool also features a symmetrical design including a trumpet-shaped nose cap to facilitate a pencil-grip tool hold. The ability to use all existing Dremel® rotary tool accessories and most attachments let the 3000 complete a wide range of applications including cutting, grinding, sanding, carving and polishing a variety of materials.
