These fast cutting Incremental finger bits have definitely carved a slot in sink fabrication on Radial Arm Machines like the Scorpion and Fab-King.
When used with a template and a Quill ( template following tool with toucher bearing ) the Incremental Cutting Finger Bits cut about 1/16" depth per pass and since they are generally run about 8000rpm and cut about 3/4" groove, they seem to work very fast.
Regent carries a wide verity of bits from names you already know and trust.
