This pack of five DeWalt DT2301L-QZ 152mm General Purpose Reciprocating Saw Blades have 10 teeth per inch and are designed to cut faster and last longer.  The superior HHS teeth have added cobalt, making them harder, stronger and more flexible for supreme cutting performance and a long service life, even in the most demanding of applications. The optimised blade design has an increased height and thickness for extra strength and extreme durability. The ToughCoat hardened coating lowers surface friction and reduces heat build up to promote long blade life while the aggressive shank angle increases tooth engagement in all materials and extends blade life.
