Lenox Snap-Back 3/8 in. x 7-1/2 in. L Steel Drill Bit Arbor 1 pc.

After reading the other reviews I had to speak up. I run a tool crib at a large plant. These snap back Lenox arbors and hole saws work well - but then, I have professional tradesmen using them. With no complaints.... and believe me if they weren't happy with them I'd hear about it.

I have used all of these and not had issues except for wearing one out to where its detent wouldn't catch in the forward position. I'm an electrician by trade and own a contracting company that specializes in electrical and plumbing in principally commercial and industrial applications. In that we drill a lot of holes and between these and Milwaukee's Big Hawgs we can drill pretty much anything we need to. As a professional these hold up well. For what the rest say these can have some fitment issues and if they do return them and get another; I've only had to do that once as there was a bad batch. The retailer I use has never given me a problem in returning a non-working item. The biggest issue I have with these is when you're using a multi-mode drill with a hammer function and forget to turn the hammer function off these will quickly pop backwards causing the threads to tighten all the way. I do prefer Milwaukee's arbors as you can cut the Big Hawg bits even faster with the hammer mode on. These however cut a much cleaner hole. I almost exclusively use Lenox cutting tools and these are no different; I just though someone should say something nice considering the quality of these tools. I don't often write reviews but when so many were negative I though it was a duty to back up such a good product.
