A qualified ski technician should always mount bindings. For mounting bindings it is necessary to use templates suggested by binding manufacturers or the paper template that comes with a new binding.
MAJESTY recommends using 3.8mm x 9mm drill bit for skis with fiberglass or carbon fibers and 4,1mm x 9mm drill bit for skis equipped with titanal layer or socket.
Ski drill bits have a built-in collar to drill the holes to a specific depth. The type of binding you have may determine the size of the drill. We strongly advise to make sure the screws are not too long. Improperly installed bindings can cause injuries. Improper installation may also void the warranty.
