What is a Dremel?

What is a Dremel?  Dremel is an American brand of power tools known primarily for its rotary tools. Dremel’s rotary tools are similar to the pneumatic die grinders used in the metalworking industry by tool or moldmakers.

The tools were originally developed by Albert J. Dremel, an Austrian immigrant who founded the Dremel Company in 1932 in Racine, Wisconsin. The company was purchased by Robert Bosch GmbH in 1993, and today it is a division of the Robert Bosch Tool Corporation located in Mount Prospect, Illinois. Dremel’s activities in Europe, the Middle East and Africa are operated by Dremel Europe, located in Breda, Netherlands.

Dremel Rotary Tools

The concept of the original Dremel Moto-Tool was to rotate a bit at high speed, the bit being held in a collet. Variable-speed versions may cover a range of 3,000–37,000 RPM. The Dremel concept relies on high speed as opposed to the high torque of a conventional power drill. By inserting an appropriate bit (or burr) the tool can perform drilling, grinding, sharpening, cutting, cleaning, polishing, sanding, routing, carving, and engraving. Both battery-powered and corded models are available. Early cordless models were marketed as the Dremel Freewheeler. Dremel options include a miniature planer attachment and a saber saw attachment that lets the tool act much like a small reciprocating saw.

Other Dremel rotary tools include a cordless pumpkin carving tool, a cordless pet nail grooming tool, and a cordless golf cleaning tool.

Similar rotary tools (for example, those sold by Sears under their Craftsman brand) are also sometimes colloquially called dremels in an example of a genericized trademark. The thread of the drive shaft on similar rotary tools tend to be manufactured to similar but slightly larger metric dimensions which are incompatible with the Dremel standard thread diameter of 0.28 inch with 40 TPI.

However, the collets are flexible and will accept both original Dremel and alternative makes of cutting, grinding, and polishing head shafts

Other Dremel Tools

Dremel produces hot glue guns, scroll saws, contour sanders, versatips, and powered screwdrivers.

Dremel is also one of the manufacturers to release an oscillating tool in late 2008 after the patent had run out on Fein’s Multimaster. Dremel’s incarnation of this tool is called the Multi-Max.

Dremel also produces 3D printers.

We will tell you the differences between single, double and aluminum cuts, and when to use them.

carbide bur cut

Choose Double, Single or Aluminum Cut Ball Shape Carbide Bur?

double cut carbide bur

Double Cut

Our double cut carbide burs allow for rapid stock removal in harder materials.  The addition of the left hand flutes reduces the pulling action, allowing better operator control.  You can reduce the size of the chips and use them at slower than normal speeds using our double cut burs.

single cut carbide bur

Single Cut

Our single cut carbide burs are for general purpose and designed for cast iron, steel, some copper and brass, and other ferrous materials.  Single cut will give good material removal and good workpiece finishes.

Aluminum Cut

Non-ferrous are exactly what you would expect them to be. Use our cutting tools on non-ferrous materials such as aluminum, copper and magnesium.

Our USA made tungsten carbide burrs can be used on most hard materials including steel, aluminum and cast iron, all types of stone, ceramic, porcelain, hard wood, acrylics, fibreglass and reinforced plastics. If you use our burs on soft metals such as gold, platinum and silver, carbide burrs are perfect as they will last for a long time with no breaking or chipping.

Different cuts of carbide burrs will be best suited for certain materials.

Uses for Ball Shape Carbide Bur Die Grinder Bits

Carbide burs are widely used in metalworking, tool making, engineering, model engineering, wood carving, jewelry making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. Our carbide cutting tools are used in the aerospace, automotive, dentistry, stone and metalsmith industries.

Carbide burs (burrs) are tools that are used for precision in cutting, grinding, and shaping the material
with which they are being worked. Additionally, you can use them for deburring, where burrs, excess
materials, sharp edges, and weld beads are removed. Use carbide burs in industrial tools, such as air
tools (e.g., die grinders), engravers, flexible shafts, and pendant drills, as well as for hobbies (e.g.,
Dremel tools). Their uses are varied and diverse, such as jewelry work, metalworking, welding,
woodworking, and cover a range of industries, including aeronautics, aviation, automotive, dentistry,
and metal and stone working.

Carbide burs (burrs) are composed of titanium or tungsten; diamond is the only material on
the Mohs scale that is harder and also used for drill tips. This means they are ideal for multiple purposes
due to the fact that they maintain sharper cutting edges for longer periods of time due, and tolerate
higher temperatures without warping when you apply friction. Carbide burs (burrs) maintain their sharp edges 10-20 times longer than a stainless-steel bur (burr), depending on the
frequency of use and the materials used with.
