Tooth pitch

Choice of tooth pitch, known also as TPI – teeth per inch = number of teeth per inch, is essentially dependent on the workpiece dimensions. Band saw blades with coarse toothing for cutting of large diameters. For worpieces, their diameter is small or for profiles, blades with more fine tooth pitch must be used, so that at lease 2 teeth are in the cut at the same time. The less number of teeth in the cut, the more cutting performance. The reason is that pressure distribution on less teeth means better ability for the teeth to get into the material. Soft materials as aluminium or bronze need enlarged space for chip removal. Otherwise it will cause its cumulation which will negatively effect on the surface quality.
