The invention relates to a method for sawing a long profile (3) in that a sawing disc (2) having teeth (6) arranged around a circular outer circumference of the sawing disc (2) is rotated freely, the sawing disc (2) is advanced from a freely rotating position to an outer wall of the long profile (3), and a zero tooth (Z.sub.1, Z.sub.2, Z.sub.3, Z.sub.4) engages as the first of the teeth (6) in the material of the outer wall, wherein, during the free rotation of the sawing disc (2), lateral runouts (d) of the teeth (6) are determined, and a tooth (6) having a minimum lateral runout (d) is determined and used as the zero tooth (Z.sub.1, Z.sub.2, Z.sub.3, Z.sub.4).
