Review on Efficient Powerbuilt 648619 Silver Pilot Bearing Puller: Ultimate Solution for Smooth Bearing Removal by Joey Pritchard

The problem is that the tool ends are rounded, allowing the bearing to slip. I brought him an angle grinder to get a little grip on his hands. After that it worked great. It's annoying that you might have to do this, but you get what you pay for. It's also the only puller that was small enough to fit in my machine's pilot bearing. It doesn't grip the camp. The tool just slides out when you apply pressure.
