| The number of
teeth per inch (TPI) is important in obtaining the finish desired and the proper feed
rate. A course tooth blade (like a 9 TPI) should be used for resawing wood and
cutting thicker stock. A fine toothed blade (18-32 TPI) should be used for thinner
materials under ¼". For general cutting of ¾" wood 9 TPI will provide a
fast cut and 15 TPI will cut slow but leave a smoother finish. When selecting TPI remember: More TPI
give a smoother but slower cut. Fewer TPI allow a faster cut with a rougher finish. |
