Used to extract/replace shot rear bearing on the 10 yr old Suki DT200 I recently bought in Costa Rica. Grabbed with 2-3 whacks and extracted with another 4-5 (3# sledge). Far easier than I anticipated. I've extracted bearings from several of my vintage Yamaha TT600s using traditional screwdriver/punch routine, and this was nothing in comparison. Only bad news is that now I need another set for my shop in TX.
