These bearings spin incredibly hard right out of the box like they have sand in them. The bearings are not sealed which is good as I plan to lubricate them with light machine oil. Does anyone know where I can order new bearings for these bits? I couldn't find any kits online, only individual bearings which I think are a bit overpriced. Overall I think the price was fair and the raw edges are all I really care about as there is a slight burning of the wood from abrasion. The roller bearing doesn't bother me too much.
