Malco TS1 TurboShear Sheet Metal Cutting Drill Attachment – 20 Gauge Galvanized Steel, Straight & Left Cut | Blind Cuts from 1/2" Hole | Replaceable Hardened Jaws | Fits Cordless & Corded Drills

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.

Love this tool it’s light and quick! I’ve started getting arthritis in my hands and this helps me do the heavy cutting which hurts my hands. Not that big and fits into my toolbag easily.

Got this yesterday and haven't used on the job but chopped up some pieces of ductwork I had in the back of my service van and worked very well but it should be noted that you almost need the drill clamp that is sold separately if you want to cut loose pieces of metal with it or you have to clamp down the metal or something. But for cutting a return hole in the furnace or cutting any hole in ductwork that is already hung I bet it would work great without the drill clamp that you have to buy. Oh and one more is that with that drill attachment connected it does not rotate, there are other models that do rotate with the drill clamp but I actually think this one probably works better because it doesn't rotate and cuts nice and straight, plus it's light weight and smaller

I used this to cut a bunch of rippled metal roofing to make planter boxes. Using this tool was much easier than tin snips or an angle grinder - I'll never go back. However, you have to get used to it: if you hold the tool at the wrong angle, it'll stop making progress. There's a certain "correct" speed for the drill (slow if you're cutting across ripples and need to guide it up and down, fast for straight runs). You have to be careful to hold the tool to keep the cutting angle just right (so that the shears cut cleanly), and the forward pressure just right (as you push it along the workpiece). I find I need to focus when using it. It's a two-handed tool - and a little finicky to use - so you'll want to clamp your workpiece to something when making the cuts. But it works great, and I'm happy I have it. Way better than the alternatives.

So I was confused by the instructions because of the round plastic shroud and most of the videos I have seen of these cutters being used. Knowing I could confidently put a round block in a round hole and a square block in a square hole as a child, I noticed there was no round anything on the cutters themselves for the round thing on the sheer guides. After looking up a bit more on here I saw that these were not the “corrugated” metal cutters, which does have the round part built on the sheets themselves. For me, this is acceptable enough. I know Malco products are quality because I own other tools of theirs and quite frankly all I needed was something to keep the cutters from spinning so I could use the cutters one handed. That being said. I think you could probably use a large rubber band or come up with another way to keep the cutting attachment from spinning if you wanted. Or you could spend the extra $50 to get the corrugated cutters which would allow you to switch from left cut to right cut. I’m a little irritated I guess but not enough to return them to get the round one. Just take your time when ordering this IF being able to switch cutting directions ( basically from red to green) means something to you. I’m a big believer that having the right tools, the right quality tools, makes the difference. If I’m going to buy it I’m going to get the best there is to make my job as easy as possible. Plus malco is a reputable company who makes quality tools. I have yet to order ANYTHING from malco and be disappointed. Which is a great feeling.

As advertised

Malco TS1 Turbo Shear 20 Gauge Capacity Sheet Metal Cutting Attachment for 3/8-Inch Drills I purchased this for my dad, for a father's day gift. I must admit that he's been in the heating and air-conditioning business for over 25years and all the stress on fatigue on my dad's hands from manual labor has been tough on him. This tool is pretty simple to use, you just get a drill electric or battery operated and just hook the sucker up. Take a screwdriver hammer a hole in so you can get the shear lips inside the hole and pull the trigger on your drill! It cut's thought most sheet metal type materials with ease, but the only difficult thing this won't do is sharp 90 degree turns so beware of that. On straight cuts this does wonders! If you are in the industry I would say this is a no brainer :) 9/10 = rating! edit- spelling*
