The angle grinder flange pair in UNF

[abdulbadii]

TL;DR Summary

is there's a grinder flange pair with thread 3/8" x 24UNF ?

Does anyone happen to know if there's a grinder flange pair, i.e. its spacer and fastener flanges, with 3/8" x 24UNF thread instead of M10 x 1.5?

If you have not found one yet, I think it is most unlikely.

Can you better describe exactly what you are trying to do?

24 TPI is a very fine thread for use on such a large flange nut, and it will almost certainly over-tighten in use and become locked solid. You will probably then break the locking mechanism while trying to undo the flange nut.
To remove a jammed abrasive disc from a grinder, heat the nut and disc with a flame. At about 150 °C, the polymer binder in the disc will collapse, so it can be undone easily.

Some adaptors are available for M14 and M10, to fit a 3-jaw chuck or an extender to an angle grinder. You might fabricate a similar adaptor for your application. Take care.

This one has a 3/8" UNF.

Need arose in making one of most common drill (here is mine) with 3/8" 24UNF shaft connector to function as grinder being able to use every kind of disc: cutting, grinding, wire disc, mounted straight onto it

You could keep the drill chuck with the drill and use the spindle from the second link I gave, or from a similar product.

Maybe you could thread the spindle adaptor to be 9/16" UNF, to eliminate the 3-jaw chuck.

But your drill may only have thrust bearings, which will not work for radial loads like a grinder experiences...

There is a reason for the shape and speed of a regular grinder.
A drill will produce very different results.
