Nice and simple this one. The hole is 3.2mm diameter, your tool is 1.6mm diameter. If the tool helically ramps into the stock at anything more than 1.5mm diameter then it'll already be over the diameter of the hole you're trying to cut.
1.5mm diameter helix on the centreline of a 1.6mm tool gives 3.1mm total circumference meaning it has .05mm stepover left to cut to reach size. Any more on the helix diameter and there would be nothing left to cut. ![]()
As a side note, its good practice to make the ramp diameter to be equal to or slightly less than the tool diameter ( to avoid those awkward moments when ramping with a none center cutting tool
)
