Hello
Thank you for reading
I was taught that minimizing run-out is essential for successful drilling
I can see machinists making dowel holes with HSS drills in collets, and sometimes these drills run even more than 0.1mm out, on steel and aluminium.
I know the spot drill defines the position of the holes, however drilling with a drill which runs more than 0.1 out, I would not use it even to make a normal tapped hole for a high precision job
What’s your experience about run out
Thank you in advance for your support
