Don't get me wrong these are great magnets and they seem strong , but WHY is Makita suddenly making them so damn proprietary for their own bitsets? The old green/black magnet bits easily fitted any screwdriver bit brand and were powerful too, but these new bits will only fit newer round body bits, not the original hex bits. If these bits were made to fit regular hex bits I would give them 5 stars but not for buying all Makita bits instead. I will not be buying these magnets again until they fix this.
