A fluid cooling device for a circular saw of centerless type having a ring-shaped saw blade, designed to be rotated about a fictitious center of the saw blade and with at least one disc (8, 108), mounted on the radially inner side of the ring-shaped saw blade. Mounting elements (9, 17) are provided at a rear part of the disc. At least one conduit (20) for a cooling or rinsing agent is provided with an inlet (22) for the conduit in the rear part of the disc and at least one outlet opening (25, 125) in the foremost part of the disc. The outlet opening (25, 125) is located adjacent the periphery of the disc and directed essentially parallel with or with an acute angle relative to a tangent at the interior edge (6) of the blade adjacent the outlet opening. |
