Drill to create a notch

The diamond drill are made Metal manufactured and accordingly very stable. The outside is painted blue, the shaft is also marked on the underside with the drill diameter labeled. The lettering on the shaft prevents it from being rubbed off during use. The shaft is as Hexagon designed and therefore also fits into standard ones Cordless Screwdriver. The actual one is located above the shaft drill bit. This is inside with cooling wax filled and has very rough, silver sparkling diamond tip. All drills are 67 mm high. Of this, 32 mm is accounted for by the actual drill bit. The diamond tip extends over 10 mm. The drills do not have a groove or any other device for removing the drilling material.
Also the Spot drill has a designed as a hexagon shaft with labeling of the diameter. In contrast to the diamond drills, however, this one is brass-colored. Unfortunately, small scratches can be seen there, but they have no effect on the function.

In our field test we use a commercial one Cordless Screwdriver. It should be noted that our cordless screwdriver only has a speed of 1800 rpm-1 reached, although the manufacturer a speed between 2000 min-1 and 3000 min-1 recommends. As Test item serves an ordinary tile, as it is also used in bathrooms. Spotting drills and diamond drills can be used like ordinary drills in the holder of the cordless screwdriver or a drill attached .
To drill a hole, as recommended in the instructions, first use the Spot drill score drilled. The spot drill does not jump, so the notch can be precise insert into the tile. The tip of the drill is very sharp and cuts through the tile quickly. Now you can switch to one of the diamond drills.
The diamond drill we first set, as described in the instructions, in the 30° angle to the tile. Due to the reduced contact area, it quickly becomes crescent-shaped Vertifung sanded into the tile. It should be noted that the speed selected is not too low. Otherwise the rough surface of the drill can jam in the previously created notch and the drill will skip. It should also be noted that the center of the hole not in the notch of the spotting bit, but slightly offset. This is because the rim of the drill bit is set into the notch.
If there is an initial indentation, the tool will slow down gekippt, and continued to drill until it perpendicular stands to the surface. To remove dust and debris from the hole, use the drill to make a light hole rotary motion carried out until the drilling is completed. Our test tile can be drilled through in a short time.
After drilling, you should wait briefly because the tool is in use heiß becomes. Since the drill is filled inside, arises no core. The four different drills behave very similarly in the practical test, no significant differences can be determined.
Due to the to be carried out rotary motion the holes become a few millimeters larger than the diameter of the hole. With something exercise succeeds, however, evenly round holes to accomplish.
Overall, the diamond drill set performed very well in the practical test. Drilling is quick and easy with the diamond drill bits, even if only a cordless screwdriver is available. For precise drilling is however practice and skill necessary.
