Review on Uxcell Chucking Machine Straight Stainless Cutting Tools for Reamers by Maurice Stavros

The reamers are slightly dented from being shipped in a box but this does not affect the finish. The surface finish of the hole was acceptable. My reamer made a 6.05mm hole. Definitely low accuracy for 6mm but may be acceptable for some applications. The file won't scratch them, so at least they're pretty solid. I've only used them on aluminum.
