Abstract:
A fluid circulating apparatus for a drill, the drill including a bit, a bit driving means that drives the bit to rotate, and a fluid inlet used to supply a coolant to the bit, whereby the drill cuts and drills an object to be drilled by rotating the bit while supplying the coolant to the bit,wherein the fluid circulating apparatus for a drill comprises: a suspension collecting means that collects a suspension derived from the coolant mixed with chippings through cutting and drilling operations; a suspension filtering means that filters off the chippings included in the suspension, thereby making a resultant coolant, in which the chippings have been eliminated, to be stored in a reservoir; and a coolant supplying means that supplies the coolant obtained by the suspension filtering means and stored in the reservoir to the bit, and wherein the suspension filtering means includes a filter tank for filtering the suspension and the reservoir for temporarily storing the resultant coolant after filtration, wherein the filter tank is disposed in the reservoir and, wherein the suspension collecting means includes a water receiving pad and a discharge channel, one end of the discharge channel being coupled with the water receiving pad and another end of the discharge channel being coupled with the filter tank.
