The SAWZALL Drywall Access blade has been engineered to specifically address the frustrations encountered when doing plumbing and electrical service work behind installed drywall. The new Drywall Access blade is only 2-1/2" long, optimized to cleanly cut through up to 5/8" drywall but avoid damage to pipe and wire behind the wall. The blade's unique multi-directional tooth design allows the user to cut in all directions, for maximum finesse in small diameter cutting.
