Malco TS1 Turbo Shear 20 Gauge Capacity Sheet Metal Cutting Attachment

These tools working very well

Des afortunadamente al momento de hacer el corte, provoca que las láminas se deformen un poco con una especia de ondas, que posteriormente es necesario reacomodar

This worked great. We used this shear to cut out 6-inch holes in our corrugated steel for can lights in our ceiling in our grain bin house. The steel was too thin for a jig saw as it would tear easily. We tried using it to make long cuts for our pie shaped pieces, but it took too long compared to a metal blade in a skil saw. Also, cutting the corrugation, you had to learn to twist the shear to be as vertical to the metal as possible or the metal would spread the cutting jaws apart and not cut. There is a learning curve, keeping the shears perpendicular to the metal, and making curves takes a finesse. They do tend to smash, or wrinkle the corrugations a bit as tinsnips would, but if you have a trim piece, that should not be an issue. Otherwise, money well spent.

Easy to use and a beginner can use it efficiently.

I watched a number of YouTube videos on the various Malco Turbo Shears. I was trying to cut a corrugated metal water tank. I wasn't trying to cut over the valleys and ridges of the corrugation, I was trying to cut along either a valley or a ridge. I could only get about 2 or 3 centimetres ( an inch and a half), then it would jam, and I could not get it to cut any further. Very disappointed, as I bought it specifically for this one job. As it was made in USA and not China, I had high hopes. I guess if you were cutting a sheet of totally flat metal, that was clamped down, It might work okay. Also more practice might help. I had to resort to an angle-grinder instead.
