Teeth Per Inch (TPI)
Reciprocating saw blades range from 3 - 24 TPI. The number of teeth per inch determines the cut speed and roughness of the cut.
Lower TPI blades cut fast but leave rougher edges. Blades in the 3 - 11 TPI range are typically best for wood and demolition work. Pruning blades tend to be at the low end, and demolition/nail-eating blades tend to be around 8-11 TPI. General purpose wood cutting blades are in the middle, often around 6 TPI, and can also cut nails.
Blades with higher TPI remove smaller amounts of material with each pass. Therefore they cut slower and leave a much smoother edge. Blades 12-18 TPI are typically used for metal and denser materials as well as finish cuts in wood. The 18-24 TPI range is almost always used for metal cutting.
Combination blades have a variable TPI and are often used for both wood and metal cutting, and demolition. Different areas of the blade have different TPI, allowing the user to change the cut based on how they position the blade. For example, a 10/14 TPI blade has alternating sections of 10 TPI and 14 TPI for cutting wood and metal. A variable 14/18 TPI blade is designed to chew through metal.
