My Ryobi angle grinder grinds weak on steel with a 4.5-inch disc, it is slow even with charged battery. Any solutions?

Check battery contacts, clean with alcohol.

Weak grinding is from worn brushes. Replace them, use a 24-grit disc, my Ryobi grinder improved. Tighten flange nut for stability, clean spindle with alcohol for faster grinding.

Use a 24-grit disc for better cutting, check battery contacts with alcohol.
