Provided the machine has enough grunt and the tool can take the strain, using the maximum amount of edge possible per cut will extend the life of the tool. This is important in industry, but even something the size of Bridgeport has limits, which is why hefty horizontal mills are popular.

A Bridgeport is versatile, you might even say flexible; but sadly in more than one sense. The tool will certainly take the strain. I understand that for smaller (larger?) DP values such as 2DP, or less, roughing cutters were available. But at that size you're talking tooth depths greater than one inch, so large by modelling standards.

Plus one on horizontal mills, never managed to even make the motor cough on mine, whereas I have stalled the Bridgeport a few times. Here's a 5DP gear in cast iron being cut, in one pass, with a secondhand cutter from the US via Fleabay:

Total cost of the machinery in this picture was less than £500, including delivery of the mill, so no need to splash out if you've got the space for a horizontal.
