Diamond drill bit set tested in 2022

The Diamond core bit set by Fairmo came in a near perfect fit Shipping box at. Inside the box was the diamond core bit set in its product packaging. Due to the right size of the shipping carton, the product packaging could only slide around a few centimeters. The diamond tile drill set and the associated product packaging were undamaged and in perfect condition.

The Product packaging is printed in dark green with orange accents and looks good with the product. Since it was not glued, it can be easily opened without tools.

The product packaging contains the suitcase with the tools. At the top of the box is a thin sheet of foam. This could have been dispensed with for reasons of sustainability. Through the two carton and the case are the tools during transport outstanding geschützt.

The Set consists of a total of seven parts: Four Diamond drill bits with the diameters 25 mm, 35 mm, 50 mm and 68 mm, one Adapter for cordless screwdrivers, one end mill and the suitcase. The set thus offers a comprehensive selection of tools for processing tiles and granite slabs.

The Instructions located on the back of the Product packaging. Here you will find a user manual with tips and warnings. The instructions for use are written completely in German and use pictures to visualize the tips. This means that the product is also suitable for handyman usable who have not previously worked with such a drill.

The Contact information can also be found on the product packaging. They are located on the bottom and include company name, address and an email address. Unfortunately, a telephone number is not given. The warnings and contact information are also printed on the back of the case.

The suitcase consists of two plastic halves, which can be quickly closed with a clamping mechanism. It has a practical carrying handle on the top. The bottom half is with black Foam material filled, which contains precisely fitting recesses for all other parts of the set. The Recesses are very tightly dimensioned, which means that the tools hold firmly in them despite their relatively high weight. The two large drills protrude from the foam and are easy to remove. The other, smaller tools and the adapter are completely sunk into the recesses. Therefore, there is a small bulge in the recess here to put your finger in. Unfortunately the recess zu kleinto grab the stuck tools with your finger. With a little effort in the fingers, the tools can still be released. In the upper half there is an additional transparent one plastic shell to protect the tools against falling out. However, since these are firmly anchored in the foam, this would not have been necessary.

The Diamond drill bits themselves are made of solid metal and accordingly very stable. The bottom is the same for all four sizes flange with M14 internal thread. The flange has two to loosen tools that are firmly screwed in from the angle grinder or adapter flat sides, which can be applied with pliers. The actual one is located above the flange drill bit. This is hollow on the inside, has two openings for discharging drilling material and a very rough, sparkling silver one diamond tip. All drills are 60 mm high. The actual drill bit accounts for 40 mm of this. The diamond tip extends over 10 mm.

Also the finger grinder has one flange with M14 internal thread and flattened sides. Compared to the drills, however, this one is thinner. The working page In contrast to the drills, it is not hollow and is completely covered with the rough diamond coating. The total height of the finger grinder is 65 mm, the working area extends over 40 mm and has a diameter of 20 mm.

The Adapter for battery screw has an M14 external thread on one side, on which the five Tools let fasten. On the other hand there is a hexagonal insert, which can easily be used in common cordless screwdriver recordings can be clamped. In the middle of the adapter there is a wider area, which serves as a stop for the tools and, like the tool flanges, has two flattened sides.

We start the practical test with the use of the tools in the Angle. The diamond core bits can be easily screwed on with the thread. The angle grinder is ready after just a few seconds ready to use.

An ordinary one serves as the test object tile, as it is also used in bathrooms. For the drilling a hole the tool is held at a 45° angle to the surface as described in the instructions. Due to the reduced contact area, a sickle-shaped indentation is quickly ground into the tile. The angle grinder can be used precise lead, the tool does not jump away. The hole is created exactly where it is intended. When an initial indentation is present, the tool is slowly tilted while continuing to drill until it perpendicular stands to the surface. Now the drilling can be completed. The drilled holes have almost smooth edges, including the edges of the Drilling do not burst. This applies to both large and small holes.

After drilling, you should wait for a short while because the tool is very busy heiß becomes. After cooling, it is as easy to change as it was mounted. In our test, the core after drilling as a disc in the tool. With the help of pliers or a screwdriver, this can be easily removed from the tool, but with a little patience you can also do this with your fingers. The recesses on the edges of the diamond drill bits prove to be very helpful here.

In the next step we test it finger grinder. It is mounted on the angle grinder in exactly the same way as with the diamond core bits. In contrast to the diamond core bits, the working surface is not at the tip of the tool, but on the side. The targeted Expand one drill hole, as well as the form-accurate one Edit of tile edges succeeds in our test perfect.

In the last part of our test we use the diamond drill bits in the Cordless Screwdriver. For this purpose, the tools are first on the Adapter screwed, which in turn can be clamped in the cordless screwdriver. This is also done quickly. However, drilling is possible with the cordless screwdriver not quite like that precise like the angle grinder. Due to the significantly lower tool speed despite the second gear, the tool tends to jump away. The cordless screwdriver has to come with you two hands and a firm grip in order to set the hole exactly at the intended point. However, once the beginning has been made and the first deepening is successful, succeed the rest of the hole just as well as with the angle grinder. This means that the diamond drill bits can also be used with a cordless screwdriver. However, who the Choice should reach for the angle grinder.

Overall, the Fairmo diamond drill bit set performed well in the practical test very well. With the Diamond drill bits holes can be drilled precisely and quickly, and with the finger grinder work out the finer points. through the Adapter the tools can also be used in a cordless screwdriver, but the use of an angle grinder is recommended.
