A recip blade needs to cut faster and last longer. Bosch delivers precision- ground teeth and thick blades for high performance in wood and metal cutting. The lineup includes blades designed specifically for durability in demolition, heavy-use and specialty applications like fiber cement.
Reciprocating Saw Blade Anatomy 7
TPI (teeth per inch) Lower TPI results in a faster, rougher cut. Higher TPI results in a cleaner cut. Variable tooth pitch has teeth that change along the length of the blade allowing both faster and cleaner cuts.
Gullet — space between each tooth The gullet collects and clears out the material being cut. Deep gullets clear material more efficiently than shallow gullets.
Blade shapes — taper and non-taper Taper-back blades are designed for plunge cutting, curve cuts and easier starts in hard-to-reach applications.
Kerf — body thickness Thin-kerf blades offer faster cutting and flexibility for flush cutting. Thicker-kerf blades offer straight, more stable cutting.
Reinforced tooth — wide tooth base with a smaller gullet Strengthened tooth design that results in longer life.
