Tips for drilling in stone and concrete
Masonry drill bits and concrete drill bits are solid drills that are suitable for drilling in various types of stone, such as brick, concrete and sand-lime brick. Our range consists of concrete drills with a cylindrical connection, SDS-plus connection and SDS-Max connection.
Tip 1: Choose the right drilling machine
Naturally, the job starts with finding the right drilling machine. For drilling through stone or concrete you need a drilling machine with a pulsating or hammering effect. There are two types of drilling machines with this characteristic that are often confused, namely a rotary hammer and an impact drill. With an impact drill you can drill well through stone, but if you want to make a hole in a concrete wall, a hammer drill is a must.
Tip 2: Choose the right drill
The big difference between a masonry drill and a concrete drill can be seen in the tip of the drill. On a masonry drill bit the cutting head of the drill is made of hardened metal. On a concrete drill, the cutting head is a very hard Widia plate.
Tip 3: Choose the right connection
What is the difference between a cylindrical connection and an SDS connection?
An SDS connection has the advantage over a cylindrical connection that it is additionally locked in the machine by the extra notches. This ensures that the machine can effortlessly withstand the large forces that are released when drilling in concrete. In this way, drilling is not only more efficient, but also more comfortable. Because this lock is a very good addition, it is not strange that the majority of our concrete drills fall under this type. Pay attention! If you choose to purchase an SDS-plus hammer drill bit or SDS-max drill bit, it only fits on a hammer drill with SDS-plus or SDS-max drill chuck.
Tip 4: Choose the right flute
In addition to different connections, there are also two different flutes with SDS-plus connection. A concrete drill with an A-symmetrical spiral has been specially developed for drilling in concrete types. The hammer drill with a straight H-spiral is able to remove grit better than an A-symmetrical spiral.
Tip 5: Choose the correct cutting head
What is the difference between a 2-cutter and a 4-cutter? First of all, a 2-cutter has 2 cutting edges and a 4-cutter has 4 cutting edges. In addition, the 4-cutter has a longer service life and the drills produce more precise holes.
