got any recommendations for a pneumatic die grinder that can safely use the extend carbide porting bits without them wobbling? I bought a real nice set of porting bits, not el cheapos, but they wobble like crazy in all 4 of my die grinders. Bits are straight and the wobbling stops with the short ones, it’s the long ones that wobble. Tried them on my Ingersoll Rand even.
