Drilled hole

  Previous topic Next topic JavaScript is required for the print function  

To obtain a drilled hole that is either a through hole or a blind hole and either with countersinking or a thread, please select Insert > Drilled hole and first place the object. In the subsequent dialog box "Drilled hole properties", you can then determine all the desired properties, in particular its placement on the reverse side.

What is a "drilled hole"?

A drilled hole is a circular cutout or a circular depression ("blind hole") in the main plate, which is made by a milling tool.

Simple drilled hole or blind hole

To obtain a simple drilled hole, you only need to set the diameter to the desired value. This is limited downward to 1.0 mm by default, as this is the smallest milling cutter diameter available.

Smaller diameter On request, smaller hole diameters down to 0.4 mm are possible. Due to the different production process additional costs are incurred

You can also configure a drilled hole as a blind hole with adjustable depth and, as such, then also place this on the reverse side of the panel.

Simple drilled hole or blind hole with bevel or rounding

With the "edge machining >>>" button you have the option of producing one or both edges of a drilled hole or the edge of a blind hole with either a bevel or with a rounding (details).

This option is not available if a drilled hole has been selected with countersinking or a thread.

Countersunk hole for standard screws

To obtain a countersunk drilled hole for standard screws with a predefined thread, please first select the desired entry from the "Countersink" drop-down list.

Then select the size of screw thread which should fit the countersunk drilled hole from the adjacent drop-down list or in the "diameter" spinner.

You can configure the "Countersunk drilled hole for standard screws" not only as a through hole, but also as a blind hole with adjustable depth and in both cases also place this on the reverse side of the panel.

The program monitors the values you have set and asks you to correct them if manufacturing inconsistencies arise.

Countersunk hole with manual parameters

To obtain a hole with a configurable countersink, first select the entry from the "Countersink" drop-down list which will be your template for the subsequent settings.

If you now check the box "manual sinking parameters", you can set all the essential parameters of the countersink to your specifications and review the results in the preview.

You can configure the "Countersunk hole with manual parameters" not only as a through hole, but also as a blind hole with adjustable depth and in both cases also place this on the reverse side of the panel.

The program monitors the values you have set and asks you to correct them if manufacturing inconsistencies arise.

Threaded drilled hole for standard screws

To obtain a thread for standard screws, please first select the desired entry from the "Thread" drop-down list.

Then select the size of screw thread which should fit the thread from the adjacent drop-down list ("diameter" spinner is not available here).

You can configure the "Threaded drilled hole for standard screws" not only as a through hole, but also as a blind hole with adjustable depth and in both cases also place this on the reverse side of the panel.

Tip – in case you have to fit the threaded screws from the reverse side of the panel In such a case, the placement of the threads on the reverse side is recommended, as these are generally beveled and thereby provide a degree of flexibility during assembly.

The program monitors the values you have set and asks you to correct them if manufacturing inconsistencies arise.

Threaded drilled hole with manual pitch

To obtain a thread according to your specifications, please first select an entry from the "Thread" drop-down list in order to then specify or fix the nominal diameter of the thread.

If you then check the box "Manual thread parameters", you can set the pitch (in mm) for the thread with the preset nominal diameter. In the preview, you can see which outer diameter is set for the thread.

You can configure the "Threaded drilled hole with manual pitch" not only as a through hole, but also as a blind hole with adjustable depth and in both cases also place this on the reverse side of the panel.

Tip – in case you have to fit the threaded screws from the reverse side of the panel In such a case, the placement of the threads on the reverse side is recommended, as these are generally beveled and thereby provide a degree of flexibility during assembly.
"Metric" and "Unified"

The threads listed under "Metric" are the ISO metric screw threads according to DIN 13-1 ("General purpose screw threads").

The threads listed under "Metric fine" are the fine pitch ISO metric screw threads according to DIN 13-2ff. Fine threads differ from general purpose threads through their steeper pitch, which is why they are mainly used as fastening threads (greater self-locking) and as set screws (more accurate adjustability).

UNC (Unified Coarse Thread) or UNF (Unified Fine Thread) describe unified coarse or fine threads, which are based on Anglo-American screw-thread standards. UNEF (Unified Extra Fine Thread) describes a unified extra fine thread. The differentiation between the fine and the coarse threads corresponds to that of the metric for the general purpose and fine threads.

Special case: Countersunk threaded drilled holes

In the event that countersunk threaded drilled holes are required for a front panel, you can achieve such a solution in two steps:

1.First of all place your desired threaded drilled hole.
2.Then place another drilled hole in the same place, configured as a blind hole e.g. as a countersunk hole with manual parameters or also with a machined edge.

You can thus configure the desired countersinking without running the risk of affecting the thread (in particular by a through hole which would damage the thread).
