| Summary | 0003893: Counterbore and countersink with top clearance | ||||
| Description | According to this forum discussion it is sensible to extend thePartDesign hole feature: - Countersink should have an additional (counterbore) depth at the top - Countersink and Counterdepth should both provide the possibility for top clearance (reversed through all).

Additional features: * Set the depth of the (useable) thread (Usually this can be made in combination with the hole depth, see below) * Option: Set the depth of the bore without the angled point, i.e. set the useable bore depth instead of the total depth. I know there are some rules for tapped blind holes how deep the core hole should be and how long the threaded part ist. But I can not find them right now... I think it was like useable thread + 4 times the screw pitch or something like that. The reason is that a normal tap has some non cutting threads in the beginning. Other CAD packages: http://ww3.cad.de/foren/ubb/upl/B/BenediktKuepper/BohrungsundGewindetiefe.JPG http://www.ask-hochreiter.de/Info/PM12/D/Gewinde00.gif The Counterbore + Countersink parts could be also available for tapped holes - in German this is called "Stufenbohrung" Like this: https://ww3.cad.de/foren/ubb/uploads/Eduard+Beser/esfunzt.jpg (Although the question is if this is really needed...) Another useful feature would be to have two default counterbore settings: A shallow one (which is the current counterbore setting) and a deeper one, where the head of a ISO4672 screw is completly hidden.
