A compass saw comprising a motor-driven reciprocating rod (1) with a tool receptacle (2) disposed at its free end for receiving the clamping shaft (6) of a saw blade (3), a receiving hole (7) and a center bolt (19) that is pre-stressed towards the receiving hole (7), being guided transversely to the reciprocating rod (1) and displaceable in a longitudinal direction (L). The center bolt (19) comprises a centering means configured as a flat bearing surface (21). The bearing surface (21) cuts the longitudinal axis (A) of the reciprocating rod (1) into a slant angle (alpha).
