The Kett PSV-534 Saw is ideal for cutting drywall, backer-board, fiberglass, and dust-producing panels. The tool easily makes plunge cuts or striaght cuts up to 1-1/16" deep. The cutting zone is protected by a spring loaded blade guard. The tool uses Kett's 3-1/2" diameter saw blades and also accepts the 2-1/2" diameter high speed saw blades for cutting mild steel up to 16 gauge or laminate materials. The vac head accepts many standard noses from canister type or in-plant vacuum systems.
