TSCM

Bought it and it worked great but the nibbler worked better for my application

if you’re a metal mechanic, you need this tool. It will make your life easier. Cutting ability: Cut is precise and this tool makes it easier to do so less work on your hands.

Worked as expected.

I give this four stars because it is very well made, very sturdy and solid, and if you need to cut sheet metal, this TurboShear is a very handy tool to have in your collection. Flat, even somewhat curvy, metal can be cut easily. But the reason for my review is to answer the question that dozens have asked: "Can this cut corrugated roofing?" The answer is both yes and no. If the roofing is loose on the ground or sawhorse, where you can maneuver your hands and tools in many directions, and you can lift and manipulate the actual metal up and down to give room for the cutting blades - then Yes, the TurboShear will cut corrugated roofing. It won't be easy and you'll struggle but it can be done. But, if the roofing is fixed, say screwed down to rafters/purlins/sheathing, (where you might be trying to cut off a wild edge) then the answer is absolutely No. If you can't manipulate the metal up or down; it ain't going to happen. You can cut the straight parts but when you get to the rises and valleys of the corrugated roofing, you'll be getting your hand shears out. But overall, given this limitation, Malco has made a very fine tool.

A little pricey, but with it if you want to save your hands, wrists and forearms when cutting metal roofing material! Love the product!

I definitely couldn't get it to work on corrugated steel roofing panels like the video showed. I had trouble with it continually loosening up in the jaws so I had to tighten the blades. A nice thing about it is the allen wrench you use to tighten the jaws stores right on the unit which is great because those kinds of things tend to get lost if you can't keep it with the tool. It was easy to fit to my DeWalt 20V cordless drill and impact driver. It was kinda hard to tighten the chuck on the drill because of the clear plastic sleeve that fits around it and even harder to remove from the impact driver for the same reason. You have to pull back on the plastic sleeve while pulling the collar around the bit on the impact driver while simultaneously pulling on the shears to get them loose. After that, I just stuck with the drill. Ergonomically speaking, it makes your drill heavy and it's really hard to navigate up and down the humps in the steel - especially using a battery-operated drill. You just don't have the room to angle the back of the drill down far enough to attack the humps in the steel at the right angle to make it cut with a big 20V battery in the way. This would probably be ok for small cuts in flat steel, but it definitely doesn't work too great for cutting up and down the humps that roofing panels have. I was cutting 29 gauge steel so I was well within the limits of its cutting thickness. As far as the cut quality goes, it does cut very cleanly with very little roughness on the edge compared to a saw blade. I'm going to keep it because it will definitely come in handy for making small cutouts for pipes, etc. It just didn't work that well for my purposes of cutting multiple steel roofing panels to length even though it is touted as being for corrugated steel. I ended up just getting a steel cutting circular saw blade which was much faster and made a better cut.

Just got this and haven't done my roofing project with it yet. Did some testing and seems great. Very thick blades and super sharp. Cuts through metal roofing material like it was paper. Easy to maneuver and quick. Seems very well built and fits on drill solidly

Great Product! I love Malco's TurboShear

Simple to set up the tool and use

Good value because your not buying another electric or battery operated tool. The drill you already own, cordless or not adapts to this shear. But more importantly it cuts the corrugation with little effort.

These shears work excellent for cutting metal roofing. They do have to held at just the right angle to make the cut go easier. A must have if you work as a roofer.

I found the clamping system fairly inadequate. The shears work well, but the way it attaches to the drill is too limiting.

Bought this to cross cut 26ga 7/8" corrugated metal. Cuts the metal easily and well. The angle of the shear is so low that the handle of the different drills we tried hit the metal when climbing out of a corrugation. Also, the clamps keep slipping off of the drills. We will need to glue/screw/modify our drills to be able to keep the shear on. The concept is correct. Good quality. But a couple design issues that need to be corrected to work properly
