If your tool only has one size collet then there could be debris stuck in the collet slits which prevent the collet from compressing down on the shaft bit when the top nut is tightened. And sometimes it just takes more torque on the nut that screws over the collet to really tighten it down on the shaft

you probably won't as the GMC operation went broke I am led to believe that ozito took them over so there is a possibility that the ozito hammer drill will use the same brushes It is worth a try other than that, many electric motors use generic brushes so may be an appliance repair shop that has a lot of repairs to hand drills and small electric motors may be able to supply a set of brushes a sample would be a big advantage when asking around

You don't mention the brand and model number so I give you this hopefully it will help. https://www.youtube.com/results?search_query=Repair+rotary+hammer
