Cutter "ballerina" adjustable wood
Did you have to make large holes in wood, plastic or ceramic tiles? Cutting tools for such diameters are hard to get. But sometimes without it to make an exact contour is almost unreal. To cope with such tasks under the force of adaptation, called in common “ballerina”.Cutters of this type are used for a variety of materials: wood, ceramics, plastics, various composites and even metal. The main difference between them is that the cutting part is small, and is capable of processing only the end zone of the workpiece, or rather its contour. This treatment is designed exclusively for automatic mode from a machine or power tool, such as a drill or a rotary hammer drill. Ballerinas are beneficial because they save a lot of time and effort to cut or mill the exact circumference of large diameters.In this article we will explain how to make such a milling cutter with your own hands from scrap materials. Let's get started! Materials:Mark up the center of the plate, we sharpen and drill with a 10.5 mm drill. This is best done on a stationary drilling machine.Next, mark up the middle of the strip, and not far from its edges with core marks for drilling. In order not to break the drill during operation, the interval of the hooked marks should be slightly larger than the diameter of the future holes. Drill holes on the marks on both sides of the plate, not reaching the edges and the central hole literally 1 cm.

- Drill or drilling stationary machine;
- Bulgarian (angle grinder) with cutting and grinding discs;
- Screw clamps;
- Drills for metal by 9-10.5 mm;
- Adjustable and open-end wrenches;

Step-by-step production of the ballerina cutterThe basis of our cutter is metal plate. It must be cut to a length of 20 cm.
