Have started engraving for a metal fabricator -
He has a torchmate plasma cnc and hopes for an air operated engraving add-on sooner than later. Meanwhile, my bot gets the job for engraving his company logo.
Have completed first piece in aluminum - naturally wants to brand all items with his logo now, and rightly so.
Next piece: Stainless.
Um.....
Should I get a spring loaded tool, or a regular engraving end mill made for stainless?
Found the either/or options here:

What's interesting is their spring loaded versions are shown with RPM ratings, unlike the diamond drag tool. Client is expecting same engraved look I produced on the aluminum - don't think a drag tool will produce that milled look he's expecting.
And if that's not enough... Looks like I'll need a 3/4 shank if I go with spring loaded based on RPM's - don't think my 2.2 spindle operates lower than 8,000*, but also don't think they make an ER25 collet in the .75" shank for the higher rpm rated model.
*(HSD spec. sheet only shows max rpm of 18k, but am certain I've had issues trying to run it below 8k.)
Ugh - Any one have a simplified recommendation?
