Not exactly right. ISO is for a large part based entirely on DIN (1917).
The International Standards Organization (ISO) standard has evolved to supersede the DIN standard, which was historically the predominant metric fastener system referred to.
Since ISO came into being most national...
Just not enough info available from this print. For your own good: This unbelievable conversion (x25.4) will kill you.
Stay with metric only. You are taken a simple part print and are making a monstrosity out of it almost impossible to to make this part. If you are making parts designed in...
Looking at your post I am sure you are trying to use the IDO 286 System of tolerances. Unless you are for some reason tied to using 6m6 for a shaft tolerance I would recommend that as a first step you decide wich one of the two systems under ISO 286 you want to use. There are two systems...
They want you to apply IT6 tolerance to a part which determines how this part - hole or shaft - is manufactured. You are required to put the IT6 tol. in the right position. Depending on the part requirements. Could be a standard hole (preferred method) with a H6 tol. combined with a shaft tol...
For manufacturing use 8H7 (+15) for the hole. H7 reamers are mostly standard and easily available.
H7 is just a little finer fit than H8. You will not know the difference.
For the OD use 8f7 (8 -13-28). This will give you a +13+43 play between parts for a "FINE" running fit.
A H8 hole would...
ISO!! Only if for some reason ISO is not available for what you are looking for, than use DIN. Most ISO standards are the same or very
close to DIN. What exactly do you need?
Tolerances for cutting tools can be found by using DIN. DIN 1420 for instance gives the manufacturing tolerances for reamers. There will most likely be a ISO number for DIN 1420.
Once you know what kind of cutting tool you want to produce or buy than you can find all your info under the DIN for...
