Bevel cuts over 45° by a 45° disk saw machine

[kess]

Happy New Year to Everyone

Using a regular disk saw machine we can make straight cuts as well bevel cuts till 45 degrees,
but what we can do if our needs are over this limit?
Yes, I know your answer, "use an angle grinder".
Ok, the using of grinder isn't problem for me,
I am familiar with its use, from years,
but why not use my disk saw machine...... why not?
