Description of Efficient Joint Taper Reamer by Drill America: Perfect Tool for Precise Joint Connections
For use in enlarging or deburring tapered holes. Commonly used in ball joint studs and tie-rod ends. Can be used by hand or machine. Use in a machine with a 1/2 in. chuck, simply remove the T-handle. High speed steel reamer.
Reamed the WJ linkage to restore full turning radius on my old Dodge W150 after replacing the high GM steering box had replaced steering gear ratio. Used my old handyman drill at it's lowest speed (250 rpm) and lots of oil. No visible wear of the reamer after an operation. I have another 4x4 steering job so I'll probably use this one again.
