Blades on the shingle cutter are replaceable and easy to install on the job.

The patented compact telescoping drill clamp adjusts to fit both length and width of popular drill sizes, including smaller bodied impact drivers.

What materials will the turbo shear cut?

TSS1 – The Turboshear is rated to cut up to 1/2″ (13mm) of asphalt shingles.

How clean is the cut?

The Turboshear shingle cutter will make clean cuts throughout the range of thicknesses of material listed above. The tool will need to be adjusted when going from very thin to thick material and vice versa.

How do you adjust the tool to get the optimum cut?

TSS1 – The clearance between the cutting jaws is adjustable in order to achieve the optimum cut for thick or thin material. To adjust, locate the 3/16” set screw on the back of the tool, towards the front of the tool near the jaws. Turn it clockwise to tighten the gap of the jaws for thinner material or counterclockwise to make the gap of the jaws larger for thicker material.
