Feinmetall : General information about drilling

The drill should of course be adapted to the type of material and the thickness of the board. It may even be necessary to drill a stepped hole to ensure a perfect fit and centering of the mounting receptacle.

Applications
In the case of fibrous materials such as glass fiber boards (HGW2372.1 / FR4), a slightly larger hole must be drilled than for other materials, as the fibers are set up in the hole.
Mounting methods

It must also be taken into account whether a receptacle is to be mounted via the guide diameter or the press ring diameter.

External influences
The assembly of receptacle always requires special care. Various parameters such as speed, feed, spiral groove length, material type and panel thickness influence the drilling behaviour.
