Suitable for HO Scale!
Insert these reamers into the axle bearings of coaches or freight cars, or ant plastic trucks. Great fOR tuning Tichy Trucks.
Twist while applying firm pressure to the outside of the bearings.

Both reamers work well to smooth out rough spots in axle bearing but will not cut the bearing holes deeper. I have Athearn 90404 trucks that I changed from roller bearing to friction bearing. The bearing holes were exposed at the very apex of the hole and partially filled with CA glue. I had to use a small drill bit to cut the bearing deeper so the reamer could actually remove the extra glue and smooth out the axle bearing. Now the trucks roll down a less than 1% grade on their own.
