Fluid Pressure Hydroblast Pumps & Accessories CJT Koolcarb Catalog Solid Carbide Non-Coolant Fed Drills

Correct fluid pressure helps insure sufficient lubrication coolant reach cutting zone

Greater times Ø hole depths and higher velocity cutting parameters typically require higher coolant pressures be utilized
The volumes givenare based on water pumped through nominal orifice diameters. Pressure fluctuations, variation inorifice area, specific gravity of fluid, temperature of fluid, frictional losses or inadequately filtered chips clogging orifice(s) will alter volumes shown.
Coolant filtration prevents clogged holes, protects mating components, increases hole accuracy and extends tool life. Roughing applications require 74 to 149 micron (200
to 100 mesh) filtration. Closest hole accuracies require 5 to 25 micron filtration.

1 micron = .001mm = .00003937 inch

Use of a sealed collet or other coolant sealing system is recommended
for optimal tool life and chip evacuation.
