RIDGID29983 Model 223S Stainless Steel Pipe Reamer, 1/4-inch to 1-1/4-inch Inner/Outer Reamer, Copper

Great bit of kit

Amazon DescriptionRIDGID 29983 Model 223S Stainless Steel Pipe Reamer, 1/4-inch to 1-1/4-inch Inner/Outer ReamerPipe reamer has a 1/4-inch to 1-1/4-inch (6 mm to 40 mm) outside diameter capacityHow can Amazon get everything wrong with this product apart from the manufacturer's name and model number.I am a retired Design Engineer and amazed that no one, has so far picked up the errors in the items description.To start with, this item is a metric tool and they should have kept the details in millimetres, as RIGID do on theirwebsite.It would appear that no one at Amazon is familiar with metric dimensions, probably due to their American origins.But to try describing the item in imperial dimensions and fractions at that, is a joke.The decimal conversion factor is simply 25.4 ie 1 inch x 25.4 = mm exactly.The reciprocal of this is 0.03937007874015748031496062992126 ie1 mm / 0.03937008 (rounded off) = 1 inch approxApplying these factors to Amazons description gives the following resultsPipe reamer has a 1/4-inch (0.25 inch, correct so far) to 1-1/4-inch (1.25 inch, where did they get that from)(1.25 x 25.4 = 31.75 mm) (6 mm to 40 mm) outside diameter capacity (6 x 0.03937008 = 0.2362205 inches)I suppose that is near enough 0.250 inches, but 31.75 mm is a long way off 40 mm.To compound all of this, if you select the middle image (the one with the item on its side) to the left of theproduct description and zoom in on the right-hand end, you can see that the size is clearly marked asOD 36 mm.I purchased this item to ream the inside of a 40 mm O/D Stainless Steel Tube. It obviously would not fit.The items description on the RIGID website is:-Pipe reamer has a 0.236 inch to 2.362 inch (6 mm to 36 mm) outside diameter capacity

It's a scam, they don't send you what you buy, however Rigid is one of the best in the UK

This product is not very good for smaller diameter piping as the point is not small (sharp) enough when used after a proper pipe cutting tool that displaces the material internally.

I bought this specifically for chamfering stainless steel tubing but it would not even take the edge off
