Spyder Mach-Blue reciprocating saw blades cut through a variety of tough materials ranging from wood with nails, to steel and stainless steel, to plastics and more. Proprietary Mach-Blue plating retains sharper cutting edges and reduces heat build-up, resulting in faster cuts and exceptionally long blade life – up to 20x longer lasting than conventional bi-metal blades.
