MalcoHC1 2 in. to 12 Sheet Metal Hole Cutter Accessory for 1/4 or Larger Drill, Multi

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.

Terrible, soft alloy! I don’t believe it will last long. Didn’t finish the first cut before drill bit broke! Waste of money! Poor product!

Easy to use and accurate

Works as described, cuts through metal like butterWarning! do not use it to go backwards, I broke several drill bits by going counter clock wise.

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!
