Fast, clean cuts in fiber cement backer board — without scoring and snapping.

The Malco TurboShear® TSF2 Drill-Powered Backer Board Cutting Shear Attachment is engineered specifically for cutting 1/2″ (13 mm) fiber cement backer board quickly and cleanly. Designed to replace messy scoring-and-snapping methods, the TSF2 attaches directly to your corded or cordless drill for controlled, precise cutting with minimal dust.

The wide skid plate stabilizes the cutting head for smooth straight shearing and precise curved cuts, including window and door arches. In addition to 1/2″ backer board, the TSF2 also cuts 5/16″ (8 mm) fiber cement siding plank.

A hardened carbon steel blade and durable skid plate provide long service life. The skid plate can be rotated to extend usable life, and both blade and skid plate are easily replaceable on the job.

The lightweight cast aluminum shear head and patented telescoping drill clamp allow 360° head rotation and secure fitment on large or small drill housings, including compact impact drivers.
