If you need to make cuts on the rear for a speaker this is your friend

Cuts metal better than most any other method I've used

It's fun and works alright

Tool works great

Great value for the price. The instructions are not very detailed so it takes a little fiddling to learn how to use it but, once you get the hang of it, it functions really great and cuts heavy gauge sheet metal like butter. Be aware that it will produce tons of sharp, tiny crescent shaped metal slivers that will stick in rubber sole shoes!

Granted this is it's first use and probably won't get used much use under my ownership. But if it keeps this up, I don't see any problems. Ever since my furnace got installed, there hasn't been a way to heat the laundry/mechanical room. And where the ducts run in the back corner closet it wouldn't make sense to put a vent anywhere else other than in the middle of the room on the furnace. I didn't want to use a pair of tin snips to mangle up the sheet metal and make a botchery of things. I didn't really know what I was to expect when ordering this, other than I was hoping it would at the very least do what I need it to. It delivered! Even coming with a step drill bit that makes a big enough hole to insert the tool. I had traced out the shape of the vent, drilled a hole in the corner. One end of the tool is fixed for straight cuts, the other end swivels for curves. I used the swivel end. Simply put, this tool is a glorified hole punching machine. It dumped the chippings outside of the furnace. So this could not have worked any easier for me. Makes for easy clean up.

Broke down after cutting 1 8 ft galvanized panel

Product works great the case not so much the case did not survive the shipping process it was beat up and smashed pretty good but the tool work flawlessly
