Document Type and Number:
Japanese Patent JPH0134767
Kind Code:
B2
Abstract:
This invention relates to a hub for supporting a diamond-edged concrete saw such that the saw can make a cut while lying flush against a planar surface such, for example, as a floor or wall. The hub (10) is characterised by a rearwardly-opening doughnut-shaped annular groove (44) bordering its hollow central core area which can receive cooling water delivered thereto from a stationary source in the form of an inlet pipe (48) and then disperse the water centrifugally on to the remote surface of the blade mounted thereon by means of passages (88) leading out of the groove and passing through the hub on to said remote surface of the blade closely adjacent the central opening therein.
