Hole Wizard is used to create this hole. Even though size M6 is selected form the Hole Wizard, hole diameter in the sketch is 5mm. I assume this is because minor diameter of the thread that is supposed to be created. I couldn’t understand this 90°. Is there any relevant between this 90° in the drawing and 118° in sketch? Part file is attached.
All these are part of GD&T Glossary and Resource Symbols and Terms and it's the basics of drafting
Counterbore/Spotface
- is used to indicate a counter bore or a spot face. The symbol precedes the dimension of the counter bore or spot face, with no space.
Countersink
- is used to indicate a countersink. The symbol precedes the dimensions of the countersink with no space.
Maha,
I see that you are using an educational version, are you a student learning SolidWorks?
The 118 degree in the sketch is for the tap drill, the 90 degree is for when near side countersink is selected (see screenshot); your model is not using this option which is why you do not see it (see other screenshot). The 5mm is not technically the minor diameter, it is the tap drill size. I hope this helps.
Thank you very much for your explanation.
Yes I am a student learning SolidWorks and having educational version of SW which is free for one year. After that I have to buy. In this list, in last two which one is good for home use? First one is very expensive.
That depends upon what you are needing to do. Many people/companies only have the standard edition, which is more than adequate for general design work.
The SolidWorks matrix lists the included abilities of each edition.
This for general design work. I wish to know whether this is necessary for general design work.
The subscription itself isn't necessary for the actual design work, but it is necessary if you want the SPs (Service Packs) and a version upgrade.
The service pack level & upgrade eligibility will depend on when you buy a SolidWorks licence.
You can opt for term licensing if you don't want to use the software on a regular basis.
Could you give me the link to learn more about term licensing.
Find more details here: SOLIDWORKS to Offer Three-Month and One-Year Term Licensing
And could you please use normal text (makes it easier to read) rather than using different color, large size and bold.
I use forum as my reference as well. To easily see what my questions are I use different color, large size and bold.
But that becomes issues for others.
Okay I avoid this.
In industries in order to do tepping first holes are needed to be created according to the pitch size and then taping is done for example to do a tapping of M6 drill of 5.2 dia has to be made for detailed info refer meryland metric thread book
Dhrumil,
I don't think this is the correct information
For a standard M6 thread, Tap hole size is 5mm
respected sir i was just giving and example and as i was not sure i gave him the name of maryland metric
There are 5 thread pitch varieties of thread for M6:
M6x1
M6x0.8
M6x0.75
M6x0.7
M6x0.5
M6x1 is the standard M6 thread & has a tap drill hole of 5mm, the others have a tap drill (in order) of: 5.2mm, 5.25mm, 5.3mm & 5.5mm
When using Solidworks hole wizard to do tapped holes, it will always show the tapped drill size (eg. M6x1 = 5mm) rather than the Major Diameter of the thread (eg. 6mm). Although you can override these values if you so wish.
If everyone has a different view which is correct? It is mere confusing for an inexperienced person.
When in question if you need to call a tap drill out machinery handbook is the reference manual you should use. The defaults in Solidworks are just that defaults based on rough standards.For non production(Student) use you should not have to worry about it too much as you move forward and do design for actual production whoever you work for should have standards they will adhere to. This would dictate what the tap drill callout requirements would be.
As far as an absolute standard it will depend on material, end condition,form of threads and post processing features. The variables for machining threaded holes are vast, there is no simple answer that meets all requirements for every part.
If you are referring to what tapping drill to use for a standard M6 thread then the values I've supplied are correct for the metric ISO standard 724. Threads - Metric ISO 724
If you are referring to the size of hole that Solidworks makes for threaded holes in the model then perhaps this thread (pun intended!! ) may help:

The drawing tells you what to do.
M6x1-6H
VØ6x90°
Edit: Hmmm, is the drill depth and thread depth on there somewhere? Perhaps your instructor can provide some instruction on appropriate parameters.
It is a YouTube tutorial not a class work.
