OTC 7497A Rear Bearing Puller Review

Specifications state that the tool will fit axle tubes with a minimum diameter of 1-3/8" and a maximum diameter of 2-7/8" axle tube . ". The spec is incorrect. I ordered this tool based on the advertised axle tube diameter range and ended up sharpening the tool to 2-1/2" before it would fit in the axle tube. If I had to sharpen the tool 2-1/2" , how would it fit into an axle with a minimum diameter of 1-3/8"? The tool worked after the change, but I didn't need to make the change.
