Drill (cylindrical cutter) forstner, Like most of the other tools similar to the appointment, it is used to create regular and neat holes in all kinds of materials. Choose such a toolkit, characterized by both the structure and price, is necessary in accordance with the material in which the hole should be made, as well as on the characteristics of the geometric characteristics of the latter.
Forcener drills Among the drills of other species are highlighted by 2 significant positive moments.
- These cutting tools due to the characteristics of their structure make it possible to get a perfectly clean round cut without chips. Special bezel, a cutting hole along the contour, crashes into a material being processed, and cuts the fibers of its texture before they do the main cutting blades. Actually, as a result, it turns out to completely exclude the appearance of chips on the edges of the generated hole, make it with completely smooth inner walls and a smooth bottom.
- Preservation of a clear movement Cylindrical milling mills during drilling provides a specialized rim, and not the center of the island, which is characteristic of the drills of other species. Such a property of the toolkit that is used mainly as a drill on wood is very in demand when it is necessary to drive holes on the end items of the product or create overlapping holes, as well as located at an angle to the fibers, from which the inner structure of the material being processed is.
From what it follows that, using the driver drills, you can create first-class openings even when their location, as well as the inner structure of the material being processed, cannot allow to ensure a clear direction of filing the cutting tools of any other species.
Dimensions and diameter
All modifications of the toolkit have a rather extensive range of diameters. The cylindrical cutters for the loops on the furniture of 35 mm diameter is very in demand. Two other slightly less sought-after diameters are 26 and 40 millimeters. The length of the shank, which is also called the drill-driven, depending on the manufacturer can fluctuate, however, it is usually typical for modern screwdrivers and electrically engines with 6 grandsons 10-12 centimeters long.
On the drive can be applied by a method of chemical engraving not only marking The dimensions of the drill I Logo manufacturer companies, but also Specialized Diving Depth Scale. Sometimes a removable dive restricter can be included in the set. It is a metal disk for a diameter of 4-6 millimeters greater than the outer diameter of the cutting tool. On the drive, the limiter is fixed by screwing into his sleeve.
How to choose?
What cutters are preferable to buy – expensive original or inexpensive from the manufacturers of third-party firms – The choice is done depending on how it will often need to be used in work. In the workshop, where the stable manufacture of furniture products is assumed, it will be necessary to use this toolkit often enough. In addition, there will be cutters of various sizes. And exclusively for your own household needs, it is unprofitable to buy an expensive tool.
With intensive application, it is preferable to buy original products, To create conditions for continuous operation and at the same time, for a long time to save tools in working condition. High cost will later pay off. For infrequent use, it is better to purchase a set of 6-7 drills of running sizes (including the cylindrical cutter cutter 35 millimeters), the cost of which will be answered by one expensive original pattern.
How to use?
To mount the loop, you will need to prepare before Place for landing. In this your helper there will be a special drill.
However, the simple presence of the toolkit is not enough. It is necessary to make it even competently. Otherwise, the list of miscalculation is the facade of your furniture, spoiled material. Repeat first on some trimming.
So, you need a set that includes:
- roulette or ruler;
- cylindrical cutter;
- electric drill;
- pencil or pen;
- individual protection means.
The set can change on the basis of a certain situation. The bowl of the loop will need to be embedded in the facade. First of all, it makes markup. The most important thing is to correctly define the center of the future hole under the bowl. The center of the hole is metholova at 22-23 millimeters from the edge of the material. This will give the opportunity to leave approximately 5 millimeters between the edge of the facade and the edge of the loop bowl.
It is recommended to practice cutter cutters, so that you can not drill the hole through or deeper than necessary. You need to drill under a minor, constantly connected electrical instrument sludge.
At the end of the work, remove all material waste, make fittings and start mounting accessories.
