Review on 🔧 Bosch AutoStart Carbide Mandrel with HDGQA for Enhanced Performance by Mario Beaklini

I bought a Bosch Bi-Metal Hole Saw and this mandrel can't even be attached to the damn thing! It was even recommended to buy both together. It has a hex head of sorts and there is no way to fit or hold standard Bosch bits to it. Nothing to screw on, no rivets. Nothing. Nowhere in the Amazon list are there requirements for what it will and won't work with. This thing seems pretty well made, but make sure it's compatible with your hole saws first.
