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. Pack of 5 LENOX 20585-156R Wood Cutting Reciprocating Saw Blades 300mm 6 TPI
