The fastest, most accurate and most silent method of making holes in wood surfaces today is the method of ring drilling. Using a conventional drill and nozzle (it is referred to as a tree crown), you can get a large diameter hole in the shortest possible time. At the same time, the depth of the hole made can be several tens of millimeters. If we compare the performance and execution speed of conventional ring drills with the values that a crown on a tree has, the data obtained will be 4-5 times higher than the power of the first tools.
Appointment
These elements are used only as a drill for through holes. In this case, the periphery of the hole obtained at the outlet has a smooth and even surface. Such a result of work cannot be exactly achieved using standard ring tools. A wood crown can be used on a wide variety of machine tools - turning, drilling and even milling machines. They are also used for multi-tool processing of wood surfaces.
Dimension
One of the most common diameters that a crown on wood has is 68 mm. At the same time, tools up to 65 millimeters wide have a shank with a diameter of 19 millimeters. If the crown on wood has a size of more than 65 millimeters, then the shank will have a diameter of 32 millimeters. As for the teeth, their number directly depends on the type and size of the device used. So, a crown on wood (including 110 mm) can have from 2 to 16 cutting metal teeth.
Benefits of using
A tool such as a wood crown is able to process and make holes with a diameter of more than 150 millimeters and a depth of up to 110 millimeters. In addition, when using it, there is no need to expend more power with a motor mechanism that drives the crown. This characteristic is achieved due to the low cutting resistance of the device. Among the main advantages of the crown, it is also worth noting the high accuracy of the holes made and the quality of the machined surface. After the expiration of the work, you will not need to further process the part and remove burrs. In this case, before work, you can not pre-align and reamer the surface. Thus, thanks to its successful design, the crown on wood allows you to perform work in the shortest possible period of time with a high level of quality and accuracy.
Usability tools
In addition to the fact that the crown on the tree itself pushes the hole of the processed material after cutting, during work there are no vibrations from the side of the tool and the device. Due to this, the friction of the crown is significantly reduced, which means that there is no formation of heat on the surface. As a result, the life of this tool compared to a conventional drill increases 3-4 times.
