Amazing!
I needed to drill out a lot of 4" holes in tin on my metal shop for lights, thought a carbide hole saw would work... don't even try it. I used a 1/2 bit as a starter hole and then used my Makita nibbler, it sucked but worked. I then saw this tool used on some social media post by a guy that builds barndos for a living. Bought this and holy crap, I will forever use this for holes in tin. Cuts like butter even on my thicker gauge PBR panels. PERFECT holes, fast and easy. Built well, heavy duty. Genius idea! GET ONE!

Expensive but works well.
Works well but the item arrives in damaged condition. Manufacture was made aware and suggested returning. The damage is going to happen any way since the frame is not inside the clamshell allowing it to get dinged and banged around. Ours had several chips in the powder coated paint. Using it is super simple but is easiest with a second helper. The drill needs to be high speed and this thing saves a lot of time making those duct work cut outs. Would recommend even if you only plan a few cuts. The cut finish is awesome like a laser cut.Price is a little high for such a simple tool but the end results show why you bought it.Suggestion to manufacture: include a pouch for the tool and allen key along with a spare cutting bit. The price is high enough to do this at no charge.

Tip to Reduce Bit Breakage
Overall a great tool. Perfect for round holes in sheet metal duct. But, I broke the first bit on my second hole in 26 gauge duct. Forty holes later, (6" to 12") I am still using the second bit. The trick was to use a screwdriver/drill combo. I put the drill in the screwdriver mode and reduced the torque setting to its lowest value (1 for my drill). It cuts just as fast as before, but as soon as the bit catches for any reason, rather than breaking, the torque clutch releases and the bit stops turning. Release the drill trigger, move back a little (1/8") and start again. The clutch releases once or twice per hole, but this slight delay is well worth not having to buy bits every few holes.Another thing I started doing was to not finish each hole as this is where the bit seems to hang for me. I leave about 1/4" uncut, then I finish the cut with tin snips.

Fast shipping and excellent packaging. The Leatherman tool feels very premium and sturdy.
