Don't use that high la. Mostly around 15krpm.
It is due to my force.
That's why I know which wan bend easily.
But sometime I use air rotary tools. This wan I don't no what rpm when full speed. I whack only.
when i first started with rotary tool many many years back, i also simply whack it with the high speed also....thinking of the faster the speed the faster i can get the job done.... It is due to my force.

now i always started with the lower speed and do few pass instead...result are much better and also bits can last longer too...
