I've got a customer using standard HSS roll form tap tools from MSC
Direct, etc.

He tells me he wants to run my machine at 3600 RPM. My gut (and some
charts) tell me 600 RPM is more appropriate.

He is using coolant, the tap hole is through 1/16" to 1/8" "sheet metal"
parts and it's a manual process with ample down time between parts to
cool the tap tooling off.

Thoughts?
