Since its invention by Albert Dremel during the 1930s, the rotary tool has been heavily favored by DIY builders, woodworkers, machinists, maintenance personnel, toymakers, and hobbyists, among others. It’s because the rotary tool is so versatile, it can be your ultimate power tool! The main reason for its versatility is its changeable bits and accessories, which you can use for various applications such as cutting, sanding, drilling, carving, engraving grinding, polishing, and so on and so forth.
Without further ado, let us explore the different types of rotary tool accessories that DIY-ers and hobbyists can make the best use for as they deal with various projects.
You can also find accessories for rotary tools that have the best quality and value:
1. Drum sanderSanding is not a fun thing to do, but you can make this job quicker and easier by using a rotary tool and a drum sander.
A drum sander consists of a shank mandrel and an attached rubber drum. The sleeve that does the sanding part is usually made of aluminum oxide abrasive material. Just slip the abrasive sanding sleeve onto the drum, and you’re now ready to start sanding.
Drum sanders come in many sizes by diameter, and the most common sizes are ½”, ¼”, 1/8”, and 3/8”. The sanding sleeves are available in many grit sizes from the coarsest (50 grit) to the smoothest (120 grit).
Among the most significant advantages of a rotary tool is that you do not need to use separate machines for cutting, grinding, sharpening, etc. A grinding stone is a rotary tool attachment made of aluminum oxide material, just like in other grinding tools and machines. It makes clean and precise sharpening on various tools such as knives, scissors and pruning shears. This attachment is also ideal in smoothening welded joints, grinding off rivets and getting rid of rust.
When you need to do precise carving, etching, routing and engraving different materials, the engraving cutter should be the accessory to use. Hobbyists, as well as woodworkers and artisans, would often use this bit. When buying an engraving cutter, make sure that they are made of high-grade steel for longer-lasting use. Also, be sure to run your rotary tool at higher speeds when you’re working with hardwoods, and slower speeds for metal.
This 1-and-1/4” cutting and shaping wheel from Dremel looks a bit unusual because it is coated with durable and ultra-sharp carbide grits. These grits allow the wheel to cut and smoothen in just a single pass.
This attachment is used in cutting, shaping and contouring virtually all types of material – softwood, hardwood, plywood, plastics, composites, fiberglass and laminates.
There are times when you need to cut some metals for your projects, and this metal-cutting wheel will do the job. The high-speed motor of your rotary tool makes it perfect for cutting metal. When choosing a metal-cutting wheel, you might as well go for the premium quality ones because they are the best value for your money. A standard cutting wheel made with fiberglass may be the most affordable, but it grinds down pretty quickly and thus has a shorter useful life. A cutting wheel made of cubic boron nitride, on the other hand, may be the more expensive option, but it lasts up to 20 times longer compared to their fiberglass-reinforced counterparts.
The diamond-wheel point accessory works pretty much similarly as the drum sander. However, the former is covered with super-sharp and durable diamond particles, which can remove any foreign material easily and quickly. The diamond-wheel point accessory is used in cutting, shaping, carving, and smoothing various materials such as ceramic, glass, hardwood, semi-precious stones. It can even work with hardened steel!
The glass-drilling bit mainly drills small-diameter holes not only in glass, but also in other materials such as ceramic tiles, stone, clay pots and even seashells. The most common glass-drilling bits have one drilling head, but there are other bits that have drilling heads on both ends. Keep the surface wet to achieve the best drilling results.The straight-cut router bit is used along with a router base to make precision routing applications in wood. When you attach this bit, it can convert your rotary tool into an instant router. You can use it for routing grooves, mortises, dados, and shallow holes, grooves or recesses for inlay veneers.
At first, this type of bit doesn’t look so promising. But appearances can be deceiving! The multi-purpose cutting bit is probably the most commonly used of all rotary tool accessories. The name of this bit speaks well of its sheer versatility and usefulness – it can cut through a variety of materials such as wood, plywood, hardwood, vinyl, drywall, plastic, laminate, and many more.
Multi-purpose cutting bits are distinguished by their deep and elongated grooves that allow you to cut various materials with just a little effort. It is ideal for edge cutting and plunge cutting.
You can tell the tungsten-carbide cutter’s appearance by its unique cone-shaped head studded with tungsten carbide, a mineral that is nearly as hard as diamonds. It is used to cut and shape tough and resilient objects such as hard rubber, epoxy, plastic, ceramic tile, as well as wood.
