I'm an electrician working downtown in a steal frame new construction building and have to punch many holes and this does the trick. Great for the middle being longer to note its at a 7/8 hole that is perfect for out MC connectors we use.

I purchased this bit to increase the 1/2" hole in junction boxes to 3/4". It worked beautifuly and never caught like other bits. I paid almost $45 for mine. Amazon has a great price on this product.

I didn't buy this from Amazon. I got it from [hardware store].

There is nothing in the packaging that states it requires a 1/2" chuck. Fortunately, Amazon prominently lists this fact in the title of the item, but [hardware store]'s web site did not.

I guess I should have noticed this in the store, but I didn't. Even if I had, I would have wasted a trip.

Few people have portable drills with 1/2" chucks. I'm taking mine back for a refund.
