Adjustable Hand Reamer Tool H4 to H14 Sizes - 15/32" to 1-1/2” Reaming Tool for Precise Hole Finishing with 6 Carbon Steel Blades - Hand Tools Reamers for Metal & Wood - 11.90mm - 38.10mm

I have given 5 stars, not because they are the best, but good value for what I need them for. After drilling bushings slightly undersize, the reamers are used to "sneak up" on the ideal fit. They are not designed to "drill" out, but shave . I have read reviews of them arriving dirty and not working etc. mine arrived individually packaged, coated in what looks like a paraffin/oil type rust protection. This is common, and needs to be thoroughly cleaned off before use, otherwise they won't setup or cut properly. They are small, and therefore delicate, but with care will do what I need them for. If you need higher presision then go buy the true machinist ones for many times the price for just one.

Good quality

Quality seems ok, not great. The blades do not all sit evenly when adjusted to size making for a less than smooth cutting experience this is based only on the two sizes I've used so far. Working on slight enlargement of hole in 2" mild steel.
