I have two negative comments for Wheeler. The "Micro set is a piece of junk, go to Harbor Freight and buy one of theirs. The second is getting replacement bits from Wheeler is impossible. In the last year I placed an order for replacements (multiple). They all came up "unavailable". Evidently my order was just cancelled, no shipment, no notification, just nothing. I have gotten replacements in the past from Midway USA but there is no cross reference between bit number and part number, another brick wall.
