The fastest, most accurate and quietest method of making holes in wood surfaces today is the core drilling method. With the help of a conventional drill and a nozzle (it is referred to as a crown on a tree), you can get a hole of large diameter in the shortest possible time. In this case, the depth of the hole made can be several tens of millimeters. If we compare the performance and execution speed of conventional core drills with those of a wood core drill, the data obtained will be 4-5 times higher than the power of the first tools.
Destination
These elements are used only as a drill for through holes. At the same time, the periphery of the hole obtained at the outlet has a smooth and even surface. This result of the work cannot be achieved using standard ring tools. A crown on a tree can be used on a wide variety of typesmachine 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 wood crown has is 68 mm. At the same time, tools with a width of up to 65 millimeters have a shank with a diameter of 19 millimeters. If the crown on the tree 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 dimensions of the device used. So, a crown for wood (including 110 mm) can have from 2 to 16 cutting metal teeth.
Benefits of using
A tool such as a wood crown is capable of processing and making 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 spend more power on the 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. At the end of the work, you will not need to further process the part and remove burrs. At the same time, before work, it is possible not to pre-center and ream the surface. Thus, due to its successful design, the crowntree allows you to complete the work in the shortest possible period of time with a high level of quality and accuracy.
Ease of use of tools
Besides the fact that the wood crown itself pushes the hole of the processed material after cutting, there are no vibrations from the tool and the device during the work. Due to this, the friction of the crown is significantly reduced, which means that there is no generation of heat on the surface. As a result, the service life of this tool is increased by 3-4 times compared to a conventional drill.
