A good customer of mine just sent in a request for a few drills and
tappers.

They want to drill and tap in a single stroke (DRAP) and are doing so in
Aluminum.

It's tough because of the thickness of the material and the fact that each
unit has to perform a two hole process. ...Yes, two drilled holes and two
tapped holes, one stroke.

...We can do it. A quick example of a single spindle DRAP operation can be
seen he https://www.youtube.com/watch?v=czK0f-R5dVQ

All I need from the customer at this point to generate a quote is:

1. Cut tap or roll form tap?

2. C-C of the two hole patterns?

3. He requested four. ...Is that four units or four holes? The partial
drawing (PNG and STEP format) I received shows four holes total, but it
also shows a part that is used in the quantity of four on his final
product.

4. Are the machines going to be manually run or controlled by a PLC, etc.

5. What direction will the process take place in? Vertical down,
Horizontal, etc.

Per Mr. Gardner's request, I have now shared some of my metalworking stuff
with you. May the conversations commence!

How about drill taps? Too thick?

Wouldn't you need different speed heads so tapping and drilling speed and
feed would match up with their respective holes and operations.
