Band saw tooth size (Teeth Per Inch) is determined by the size and type of material to be cut and the desired finish. To select T.P.I. using this chart, find the colored chart for the type of material you wish to cut. Move up to the correct material size next to the chart. Follow across to the chart for the appropriate T.P.I. for your blade.
Blade Teeth per inch For high speed cutting of aluminum, cast iron, bronze, brass, copper, galvanized pipe, mild steel, and also tougher steels including chrome and tungsten steels at slow speed.
What is the proper blade TEETH PER INCH (TPI) or pitch? To achieve a smoother, more refined cut choose a blade that has more TPI. High TPI configurations should be used on thinner materials and may require a reduced material feed rate through the blade.
TPI is arguably the most important decision when selecting a band saw blade. Use Dakin-Flathers bandsaw teeth per inch chart for optimum performance.
A finer tooth saw blade setting — 18 to 32 TPI — should be used for thinner metals and plastics under 0.25″ (or 1/4″). Industry standards are — a minimum of 3 teeth in the cut — a maximum of 24 teeth in the cut — with the optimum number of 12 teeth in the cut.
TPI is the number of teeth the blade has per inch. If you’re looking to cut wood or other soft materials, you’ll need a blade with a TPI of 6 up to 20. For harder materials like metal, a TPI between 14 up to 36 is more suitable.
Band saw tooth size is determined by the size and type of material to be cut and the desired finish. Select a tooth per inch (TPI) based on the charts below. Find material dimensions on bottom of chart and move up for appropriate teeth per inch.
Blades come primarily in the four tooth configurations shown above. And the number of teeth per inch (tpi) matters as well, because larger gullets (the space between teeth) allow for better debris removal; but more closely spaced teeth deliver a smoother cut.
TPI (Teeth Per Inch): TPI is the count of teeth in a one-inch segment of a saw blade. It’s a density measure, indicating how closely packed the teeth are on the blade. The higher the TPI, the cleaner and finer the cut.
