Lenox Gold Power Arc Curved Blades deliver up to two times the cutting life of standard Lenox straight blades. The Power Arc’s curved design optimizes the cutting angle, allowing the blade to cut aggressively and more efficiently versus a straight blade. The aggressive blade design and proprietary technologies, such as T2 Technology and a titanium coating, enable Lenox Gold Power Arc Curved Blades to achieve extended life by helping to disperse heat – a common reason reciprocating saw blades wear out quickly, allowing the blade to last longer. The Power Arc blades are designed for wood and metal cutting, as well as demolition and extreme heavy metal cutting applications.
