PacTool SS724 Snapper Shear Pro - Fiber Cement Cutting Tool

In this review the PacTool SS724 Snapper Shear Pro is examined as a dedicated solution for cutting fiber cement backer board; it is best for tradespeople and serious DIYers who need a cordless, low-dust method to make straight, angled and small-radius cuts. The bottom line: this attachment turns any 18V+ cordless drill into a capable power shear that slices HardieBacker with less airborne dust and far greater maneuverability than scoring and snapping, making it a useful addition to a tile or siding installers kit.

Key Features

• Cordless compatibility: Works with any 18 Volt or higher cordless drill so users can convert an existing drill into a dedicated fiber cement cutter without extra battery systems.
• Versatile cutting: Can make straight, right-angle, curve cuts and cut circles down to 3-in diameter on 1/4 to 1/2 in HardieBacker, letting installers handle common patterns without switching tools.
• Low dust operation: The shear design minimizes airborne dust while cutting, which makes it safer and more practical for indoor tiling and renovation jobs.
• Swivel head: A freely rotating swivel head gives easier control when following lines and pathways on the board, improving accuracy on curved and angled cuts.
• Carbide jigsaw blade option: The Freud Diablo DJT141HM 4 in 6 TPI carbide jig saw blade adds extreme durability for abrasive materials, extending cutting life compared with standard blades.

Who It's For

The PacTool SS724 is aimed at professional tile setters, siding contractors, and serious DIYers who work frequently with HardieBacker or similar fiber cement boards and want a cordless, low-dust alternative to scoring and snapping. It is particularly useful on indoor jobs where dust control matters and when a variety of cut types are required on the same board.

Those who should look elsewhere include users who need a full dedicated power tool for very heavy production cutting or craftsmen who prefer pneumatic or corded high-output shears for continuous high-volume work; for occasional hobbyists who only make a few simple cuts a manual shear or scoring tool may still suffice.

Pros & Cons

Pros

• Converts a standard 18V+ cordless drill into a fiber cement cutting tool for jobsite flexibility.
• Makes precise straight, angled and small-radius cuts, including circles down to 3 in, without scoring and snapping.
• Minimizes airborne dust, making indoor use more practical and reducing cleanup.
• Pairs with the Freud Diablo carbide jig saw blade for much longer life in abrasive materials.

Cons

• Some users report mixed long-term durability; it is a heavy-duty attachment but occasional failures have been mentioned.
• As an attachment it relies on the drills ergonomics and battery life, so extended continuous cutting depends on the host drill and batteries.
