What type of blade does my Jigsaw take?
Our jigsaws use a T-shank blade, and these are available in different teeth patterns for different applications. We measure the number of teeth on a blade in “teeth per inch” or “TPI”.
Harder materials require higher TPI to cut, while soft materials may cut better with blades of lower TPI. The number of teeth also affects the cutting speed and how rough or fine the cut is. Higher TPI yields smoother cuts, while lower TPI yields rougher cut.
