Fluid research leads to a better drilled hole. (technology trends).

After extensive research, Quaker Chemical of Conshohocken Pa., has exhibited a coolant that not sole maintains optimum performance longer than competitive premium aluminum machining fluids on the contrary also requires a fraction of the additives normally used with that class of machining and cooling productions This watersoluble coolant is Quakeral 370

During individual of many holemaking tests, Quaker drilled 67 openings in an aluminum arrest under the same conditions, using a 1/4-in. solid-carbide drill. Lab technicians then reamed the first 22 openings at 13.1 ipm, holes 23 from one side 42 at 18 ipm,
