Now, this is what I call an efficient hole saw accessory within the Cutting Tools category. As a loyal customer of Industrial and Scientific products, I needed something that would make drilling holes easier and the Irwin Hole Mandrels did just that. As a result of my tests, I determined that they are durable and long-lasting. The only con I have is that they are slightly more expensive than other mandrels in the market, but it's well worth the investment.
Pros
Efficiently drills clean and accurate holes in sheet metal and plastics.
Cons
Some users may find the mandrels too small for larger drilling tasks.
I bought an IRWIN Hole Saw and the recommended IRWIN Mandrel and it's nowhere near compatible! The diameter of the middle thread is completely different. It would be nice if they mated them properly as driving them with a hole saw without a mandrel is pointless!
.to know its thread and pitch: 1/2-20. I don't know the thread and pitch of sister item 373001, but this item 373002 is definitely 1/2-20. It works reasonably well with 7/8" and 1-1/8" hole saws and probably other sizes, but I've tried the two sizes mentioned. so I can testify. Docking 1 star due to lack of relevant information on the label.
