They have superior HSS (high speed steel) teeth with added cobalt for harder, stronger teeth with greater flex for excellent cutting performance and long life, even in the most demanding applications. The blades have an optimised blade design offering increased height and thickness for sturdiness, strength and extreme durability. The ToughCoat hardened coating lowers surface friction and reduces heat build up to promote long blade life. Another feature is the aggressive shank angle that increases tooth engagement in all materials and extends blade life. DEWALT DT2301L-QZ 2X Life General Purpose Reciprocating Blades 152mm Pack of 5
