Make fast, accurate cuts in fiber cement siding anywhere on the job with a versatile and powerful TurboShear Drill Attachment. Malco's one-hand operation fiber cement shears quickly insert into the chuck of a corded or cordless electric drill or impact driver. Smooth, easy one-hand operation always leaves a free hand to steady the work when making cuts on a bench or scaffolding. A wide skid-plate on the head design stabilizes cutting action for extra-smooth results in 5/16 in (7.9 mm) fiber cement siding plank. Malco's versatile fiber cement shears also navigates curved-pattern cuts for window and door arches. One blade and skid plate set will last an average of 30 residential siding projects. You can even rotate the tool's skid plate to maximize acceptable cutting life. And the long-wearing blade and skid plate are also easily replaced on the job. A sleek, lightweight aluminum cast shear head and molded drill clamp allow maximum portability and ease to go wherever the work is. The patented compact telescoping drill clamp adjusts to fit both length and width of the drill housing including smaller bodied impact drivers. Optional spacers are stored on clamp for larger motor housing. The clamp collar allows the shear head to be rotated 360 deg and set in any position for optimum tool clearance or to facilitate easy material flow.
