LENOX® Bi-Metal Wood Cutting Reciprocating Saw Blades use POWER BLAST TECHNOLOGY™ to increase blade life. High-speed blasting along the cutting edge strengthens the blade to reduce breaks and increase durability. Patented T2™ Technology reduces cutting forces on each tooth and optimises chip removal to allow efficient cutting in the widest range of materials. Each blade has a unique configuration including an aggressive tang angle and tapered blade shape to allow for cutting in tight areas. The special design minimises friction and heat build-up whilst cutting. Ideal for cutting wood: clean or nail embedded.
