ABSTRACT:
A lapidary saw is provided including a flat rotary blade having a circular peripheral cutting edge with the blade supported for rotation in an up-sawing angular direction for cutting a stone at a cutting station with an upward sweep of the saw. A bottom portion of the blade is continuously immersed in coolant contained within a reservoir, and a shroud is mounted to enclose a peripheral portion of the saw blade in underlying adjacent relation to the cutting station for positively discharging coolant, upon blade rotation, from an upper end of the shroud directly into the cut being made in the stone by the saw blade.
