Forstner Drills


These drills are designed for drilling blind holes with a flat bottom in materials such as plastic, wood, as well as all kinds of its derivatives (fiberboard, MDF, chipboard, etc.). The main advantages of such drills are their design features. So, the center of the drill is pointed and therefore, to start drilling it can be clearly positioned without tipping. In addition, the cutting edge and the entire plane of the working surface after the start of sampling of the material tightly holds the drill in the formed hole, due to which it perfectly holds the specified direction. The fibers of the processed material are cut around the circumference even before they are touched by the main cutting edge, for this reason all kinds of surface damage outside the required diameter are excluded and, as a result, the edges of the finished hole will not be torn. To achieve the best result, it is important during operation to ensure rigid fixation of the surface to be machined, and to feed the drill itself perpendicularly, starting at low revs.

This lot contains drills for drilling holes of the following diameters: 15 mm, 18 mm, 20 mm, 22 mm, 25 mm, 28 mm, 30 mm, 32 mm, 35 mm, 38 mm, 40 mm, 45 mm, 48 mm, 50 mm, 55 mm, 60 mm, 65 mm, 70 mm. The drills are made of high speed tool steel (HSS), packaged in a plastic case and copiously greased out of the box. They are also marked with the diameter of the hole they cut. Note that for drills with a diameter of 15 mm to 40 mm, the shank will be round, for drills with a diameter of 45 mm to 70 mm - hex. In case drill bits of large diameters are required (from 70 mm to 100 mm), attention can be paid to this lot.

Quite good drill for its price. Manufacturers will appreciate them. of furniture and all kinds of carpentry. These drills can be used both in machine tools and in hand-held power tools.
