LENOX's 9 in. LUMBERWOLF Reciprocating Saw Blades, 6 TPI provide a practical combination of blade length, aggressive tooth geometry, and reciprocating-saw versatility for professional and heavy-duty work. The coarse 6 TPI configuration is particularly useful when cutting thicker wood because its larger tooth spacing helps clear material during each stroke. This makes the blade a useful choice for contractors, carpenters, remodelers, and demolition crews working through lumber and similar materials. Its 9 in. profile offers additional reach for deeper cuts, while the reciprocating blade format allows quick installation in compatible saws for efficient cutting in demanding work environments.
