  • Well built and does its job...
Pattern Name: Accessory
This product is rugged and does its job well. You really feel the heft when you use it. Only thing I suggest is just make sure that you tighten the nut down well before making your cuts with the device. The first time I used it, I just hand tightened the nut and it came loose. That's my fault, not necessarily the design of the product. It takes a 3/4" wrench to tighten the nut, although a small bar to turn it would also work. I would suggest they include a bar or small cheap wrench to tighten it with as much as it costs. There's probably even enough room to store such a tool in the handle. The paint will get a little scuffed up where the nut tightens. But that should be expected. But overall it is sturdy and works well. ... show more

  • Great tool!!
Pattern Name: Accessory
This new rendition has solved the problems of their prior product! The cut was absolutely perfect and smooth. It’s really easy to use. Seems a lot more durable than its predecessor. Good value for the workman. Fits all drills pretty much It cut this 8 inch hole perfectly in HVAC flat stock for my kitchen fan. ... show more

  • Amazing!
Pattern Name: Accessory
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! ... show more

  • Expensive but works well.
Pattern Name: Accessory
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. ... show more
