DREMEL
Frequently asked questions
Common questions about DREMEL from 3G Electric.
What shank diameter do Dremel rotary tool accessories typically use?
Most Dremel rotary tool accessories, including carving bits, grinding stones, cut-off wheels, and polishing points, use a 1/8-inch (3.2 mm) shank diameter. This is the standard for Dremel rotary tools and many compatible third-party tools. Some accessories, such as the Dremel 9902 carving bit, have a 1/8-inch shank. Always verify shank size against your tool’s collet capacity before ordering.
Are Dremel oscillating blades compatible with other brands of oscillating tools?
Dremel oscillating blades with Starlock mounting (e.g., MM480U, MM501U) are designed to fit Starlock-compatible oscillating tools from multiple brands, including Bosch, Fein, and Makita. Starlock is a universal interface standard. However, Dremel also offers blades with other mounting styles; check the product specification for mounting type. For non-Starlock tools, use Dremel’s universal adapter or select blades with the correct interface.
What materials can the Dremel MM480U oscillating blade cut?
The Dremel MM480U oscillating blade is specifically designed for cutting wood. It has a carbon steel body and a 1 1/4-inch blade width, optimized for flush cutting in wood materials such as softwood, hardwood, plywood, and MDF. It is not intended for metal, masonry, or plastic. For other materials, select blades with appropriate tooth geometry or carbide grit, such as the Dremel MM501U scraper blade for adhesive removal.
What is the maximum RPM rating for Dremel cut-off wheels like the 426?
The Dremel 426 cut-off wheel kit (1 1/4-inch diameter, 0.05-inch thickness) is made of reinforced fiberglass and is rated for a maximum operating speed of 35,000 RPM. This is standard for Dremel cut-off wheels. Always adhere to the maximum RPM rating to prevent wheel breakage. Use with variable-speed rotary tools set to the appropriate speed for the material being cut.
Can Dremel polishing wheels be used on metal surfaces?
Yes, Dremel polishing wheels such as the 429 (felt disc, 1-inch head) and 414 (felt disc, 1/2-inch head, 6-pack) are suitable for polishing metal surfaces including steel, aluminum, brass, and copper. They are unmounted and attach via standard screw or threaded point. For best results, use with a polishing compound appropriate for the metal type. These wheels are also used on plastics and painted surfaces.
What grit options are available in the Dremel MM80W sanding sheet set?
The Dremel MM80W sanding sheet set includes 18 sheets in three grits: 60 (coarse), 120 (medium), and 240 (fine). Each sheet is 3 3/16 inches wide and made of aluminum oxide abrasive. This set is designed for use with Dremel oscillating multi-tools for sanding wood, paint removal, and surface preparation. Individual grit sheets can be reordered separately if needed.
