To provide a band sawtooth capable of being produced at a low cost.

The band sawtooth 1 to be used particularly for a polished material comprises a band body 2 and a protrusion 3 provided at one vertical edge of the body. The protrusions has one mounting portion 12 to which one compact 5 formed of a hard cutting material is fixed. The compact has in a main extension plane 6 of the band sawtooth 1 a predetermined cutting edge 10 extending transversely to a cross section plane 15 and the main extension plane 6. The protrusion 4 forms a tooth 3 together with the compact 5. The cross section plane 15 of the compact 5 is defined in the main extension plane 6 of the band sawtooth 1 by a circular line 16 at a side to the mounting portion 12 and defined by a front side line 17 of a plane 18 at the opposite side to the mounting portion 12, and the circular line 16 and the front side line 17 are arranged to form a wedge angle 22 smaller than 90°C and a clearance angle 23.
