With the Dewalt DT99554-QZ reciprocating saw blades, you power smoothly through nail-embedded timber and salvage wood without stripping teeth. Hardened bimetal construction combined with a 6TPI tooth design delivers fast, aggressive cuts during demanding demolition and remodeling projects. The Extreme Runtime design reduces friction and heat buildup, allowing you to get significantly more cuts per battery charge on your cordless reciprocating saw. Measuring 152 mm in length with a universal shank, this pack of 5 blades fits standard reciprocating saws and offers exceptional durability against tooth breakage on tough job sites.
