Carbide forstners ? I've never heard of such a thing.
Carbide isn't generally a sharp as a good steel, and sharpness is a
good thing in a Forstner if you want clean edges. The only carbide
I've seen has been the sort with a radial edge rather than a
circumferential spur, intended for man-made boards. They're handy for
MDF, but they're a bit of a ragged cut in ash or soft maple.
My best Forstners are Clico, which were 3x the price of my "decent"
set. I also have some comedy Chinese sawtooths, which are only for
testing the torque of drillpresses. They got a lot better though,
after some work with a diamond file.
