TurboShear® – Corrugated Metal Cutting Drill Attachment

Malco’s TSCM TurboShear works better and faster than manual metal roofing shears. This versatile and portable TurboShear fits a drill you already own to make easy cross cuts, fast lengthwise cuts, and precise circular and square outlet cuts in large or small pattern corrugated metal roofing and common trapezoidal (box) pattern metal roofing panels. Elongated blades with compact jaws create a steep 75-degree offset so that the drill is held at a nearly vertical approach when starting a cut. As these offset blades follow the rising angle of a corrugated or trapezoidal profile, the drill handle or battery pack has clearance to naturally tip downward and still clear the roofing panel surface. The shear can operate at high or low speeds for the control you need to follow a precise cut line. Heavy-duty gearing and beefy, hardened carbon steel blades combine to offer long service life in 30 to 24-gauge (0.31 – 0.61 mm) roofing panel metal. A lateral blade adjustment capability ensures that optimum cutting performance and maneuverability can be maintained for the life of the blades. Replacement blades are also available and are easily installed on the job.

A sleek, lightweight aluminum-cast shear head and compact molded polymer patented drill clamp allow maximum portability and ease to go wherever the work is. The telescoping drill clamp adjusts to fit both length and width of popular drill sizes including smaller bodied impact drivers. Optional spacers are stored on clamp for large motor housings. The clamp collar allows the shear head to be rotated 360° and set in any position for optimum tool clearance when navigating profiles or to facilitate easy material flow.

This is an amazing tool for the corrugated metal siding…
This is an amazing tool for the corrugated metal siding i installed on my shed project. Very impressed with how well it worked. No sharp edging as with other brand shears or snips.

It is very good, but it will be better if the bit can fit with the impact drill.

Had a little trouble with the ridges but worked through it ok.


Must have for metal work
I'm a contractor. I do several metal roof jobs a year. Was skeptical when I first bought this but it was definitely the best decision. This tool cuts cutting time in half. It leaves a very smooth edge that won't cut you like snips will. Very much recommended.


Good buy
Not perfect, but well worth the investment.

Works great. Could not have done the job without it.
REALLY works! Edges are not very sharp. Once you get the hang of it, works great. Could not have done the job without it.

Worth every single penny
Worth every single penny. Took a minute or two to get the hang of it, but once it starts cutting, it cuts smoothly and quickly leaving no significant burrs at all.

A Must Have Item!!
Great! I bought this for my husband and he loves it. He said the work is a lot easier now. Thanks.
