Anyone have experience with Allied Machine "guided t-a drills" or "stealth drill"? These are an indexable spade type of drill with carbide wear pads to guide it straight. We are considering them for a production job, where we need to drill 1.000" dia and 1.1875" dia through holes both to 8xD depth. Part material is 7075-t6 aluminum forgings, machine is a VF4-SS with 300psi TSC, cat 40 taper, 30hp spindle. Our primary concerns are whether or not 300psi coolant is sufficent, and will the machine have enough horsepower for the task at hand.
