Well made hole saw bit, but you have to look at the teeth to see how well they hold up. I've used it once and it did the job perfectly, but there has been some wear on the teeth, which wasn't a pleasant surprise. So I doubt it will last as long as advertised.
I order Milwaukee 49-56-0237 4-3/4" ice hardened hole saw for cutting pc cases for 120mm Fan. It just won't cut unless I'm working on a hole for hours and using a lot of electricity, not to mention burning the rubber belt on the drill. lol. I thought Milwaukee had a good reputation as a brand. I have a second one Thoughts I rma it and hope they will be happy to refund my money.
