A question I get asked more often about wood carving concerns the rotary tools. Of course, my new students in woodcarving know more about the traditional carving tools like wood carving knives, chisels, gouges, rifflers, mallets, and leather thumb guards. But more often, they do not know much about the rotary tools for wood carving.
The rotary tools, of course, have quickly become an indispensable tool for professionals and DIYers woodworkers. Besides, a workbench is incomplete if you don’t have a rotary tool at hand. This tool can do amazing things like drilling, cutting, sanding, grinding, cleaning, and carving. With the rotary tool at hand, your creativity as a woodworker dramatically expands.
Understanding Rotary Wood Carving Tools
A rotary tool is a compact tool that comes with varied attachments to perform different jobs. In most workshops, the rotary tool is primarily utilized for grinding away thin metal layers. Yet, you can also use it for buffing, engraving, and roughing. Additionally, a rotary tool can shred different types of materials.
But when it comes to wood carving, it uses burr bits that are meant for wood carving. To produce fine details, you can use tapered or pointed-shaped burr bits. On the other hand, you can use tapered and cylinder shapes for heavy types of wood shaping.
Although the work type you can perform with your rotary tool depends on the attachments you would use with it, its motor’s high-speed rotation offers its users excellent versatility to deal with different types of applications.
The speed of rotary tools varies from one tool to another. But you will often find rotary tools that can spin beyond 30,000 RPM. Besides, its small diameter allows it to reach greater RPM.
Specific Applications of Rotary Tool for Wood Carving
You can complete a wood carving project using your carving knife within 10 hours, for example. But using a rotary tool, you can complete five projects with minimal effort within the same amount of time you would spend using a carving knife. Hence, the rotary tool is undoubtedly a very efficient tool for wood carving usage. As a beginner, it will be useful to know the following different applications of the rotary tool for wood carving:
Cutting is the process of narrowing down the wooden block size to prepare it for roughing out. You usually do it at the onset of the carving process to prepare for the succeeding steps. During the cutting process, you would usually cut the wood at 90°. You can do this by attaching a cutting wheel accessory to the rotary tool.
Roughing refers to the removal of greater portions of wood to get it into a general shape. You will use an aggressive burr bit that can eat out a large portion of the wood. This burr bit features rough edges and ridges. It also comes in various shapes like a sphere, cone, or cylinder. Its exaggerated edges and ridges make it easy for woodcarvers to chip off a larger chunk of wood.
Shaping uses specific bits to add and render the intricacies and details of the wood carving project. The bit’s size matters most at this point, and the smaller the size of the bits, the more precise your rendering of the details.
Sanding is the final process in the wood carving process. You should use another attachment for this process, and most wood carving rotary tools come with an attachment for sanding.
Buying Guide: Factors To Consider
Given the myriad of rotary tools for engraving in the market today, you may get confused about which one to choose when buying one. So that you can zero in on the right one for your needs, you need to be cognizant of the following essential factors to consider when shopping around for a rotary tool for wood engraving:
Motor sizes can factor well in the capacity of a rotary tool to cut through workpieces. Of course, a more powerful motor will be excellent for carving out any materials from hardwood to any other type of materials. Nevertheless, a one-amp motor will be enough for engraving purposes, though you can use more powerful motors for your more intricate engraving projects.
Wood carving is different from other types of carving. Hence, it will be helpful to use a rotary tool with higher speed when doing the wood carving. There’s a greater likelihood that you will have a clean finish with no burn marks with higher-speed motors.
Moreover, rotary tools are designed for delivering several thousands of rotations per minute. Hence, most of them are of higher speed.
Nevertheless, it will also help if you choose something with variable speed options or settings. Some rotary tools allow you to vary speed while operating them, while others need to be shut off first when changing speed. A workable rotary tool is expected to deliver between 5,000 to 30,000 RPM.
The materials, out of which a bit is made, also matter when choosing bits. Rotary engraving bits are usually made of two materials: high-speed steel (HSS) and carbide tungsten. Carbide lasts longer than high-speed steel, and they are more expensive than the HSS bits. HSS bits, however, dull faster, and as such, they are cheaper. Nevertheless, you can get by with the HSS if you seldom use your rotary tool.
The bit’s diameter signifies the amount of material you can remove per rotation of the bit. Bits come in different diameters. Some bits are as small as 1/4 inch, while others are as large as ¾ inch. When using larger bits, you are sure to remove more materials from the wood. Nevertheless, you compromise with your level of control when using larger bits.
On the other hand, smaller bits let you have more control and greater precision with your engraving. Moreover, with smaller bits, you can work with ease, even when dealing with intricate details.
Pointed and Cylindrical Bits
As you shop around for rotary tool bits, you will find the two most suited bit types for wood carving and engraving. These bits are the pointed and the cylindrical bits. The pointed bits, of course, have fewer surface areas than the cylindrical bits. Thus, if you want to remove tons of materials with one sweep, you can use the cylindrical bits.
Cylindrical bits can help you dig deep into the material. Nevertheless, you can use the pointed bits for more refined and detailed engraving. Moreover, pointed bits can help you deal with the details of the carvings.
