6 General Infor mation Band Length The length of a bandsaw blade depends upon the sawing machine being used. Information for specific machines can be found in our software program, BandCalc TM , see page 28, or from your sawing machine manufacturer . Band Width The band width is measured fr om the tip of the teeth to the back edge of the blade. On [...]

T eeth Per Inch (TPI) The number of teeth per inch (TPI) defines the pitch of the blade and can vary from less than 1 to 24. Thin-walled workpieces like tubes, pipes, sheet etc., requir e fine teeth, otherwise there is a risk of tooth damage or breakage. Large cross sections should be cut with a coarse-pitched saw , i.e. fewer teeth per inch. The f[...]

General Infor mation 8 Feed Rate/Chips It is important that each tooth of the bandsaw blade cuts a chip with the right thickness. This is determined by the selection of tooth pitch, band speed and feed rate. Start by selecting the right tooth pitch from the diagrams on page 9 and 10 then set your band speed according to the diagram below . Y ou can[...]

General Information 9 T ooth pitch for solid workpieces The diagram below will help you select the right pitch for cutting solids. The ideal choice is at the widest point of each field. Example 1: When cutting a Ø 6 inch (150 mm) bar , use 2 TPI, if an evenly pitched blade is your choice. Use a 2/3 TPI or a 1/2 TPI if you choose a variably pitched[...]

10 General Infor mation Cutting pipes and profiles The diagram below will help you find the right tooth pitch for cutting pipes and profiles. The recommended tooth pitch for cutting pr ofiles is found in the field where the width meets the wall thickness of the pr ofile. Example 3: When cutting a 4" x .4" (100 x 10 mm) U-beam, select a 5/[...]
