Diablo's bi-metal reciprocating saw blades provide the best cutting performance on the market. Perma-SHIELD coating protects these blades from heat, gumming, and corrosion. Patented aggressor Variable tooth technology incorporates a tooth count per inch (TPI) that drastically increases from the shank of the blade to the tip – allowing for super-fast cuts with less vibration.
