I fairly routinely make 1/2" deep passes feeding at 1-1/2"/sec
(90"/min) with a two-flute up-spiral bit spinning at 18,000 RPM. On
occasion, I've made profiling cuts a full inch deep with a straight
bit. If the bits are sharp, hard maple cuts beautifully.
The sharper the bit, the easier it is to control the router - at any
depth of cut. If the router is underpowered, it forces a slower feed
by removing stock in front of the bit more slowly and could lead to
overheating (and dulling) the bit. This hasn't ever been a problem for
me (my least powerful router is a PC690); and I doubt it's the OP's
problem because he'd have been able to hear his router bogging down.
Cheap router? Maybe - but I'd consider the bit sharpness to be the
most probable culprit.
