Hydraulic Port tooling concerns
I have just started my project of reverse engineering all our hydraulic manifolds. I am trying to build our manifolds in house to cut down costs. I understand the basic port tooling; where a porting tool does the spot face, seal angle, and thread depth. Then use thread milling for the threads. My concern is what tools to use beyond the thread depth. Even deeper than the threads on our manifolds are more, multiple smaller diameters going deep into the part. So this is where my question lies... Do we just use different sized drillbits to obtain those deeper depths and diameters??? Or are there more kinds of porting tools that do what i specified above, and also the deeper smaller diametered holes?
any advice is greatly appreciated
tooling recomendations would be nice

I make aerospace hydraulic ports. We use the appropriate porting tool behind drills.
In another life I made hydraulic ports for power steering gears. We used special made burnish drills which sized all internal features. We face milled the external surfaces. These drills were carbide with PCD brazed on the cutting surfaces. We machined high silicon aluminum castings and they are very efficient making well over 10,000 holes per sharpening. In large quantities they cost $250.00.
Will you be making the same holes over and over? If so, a form drill might be worth the cost.
Step drills? w/wo Mapal or Cogsdill reamers.
