Inserted tooth edger saws

I had a friend call me and ask for some help designing some saws for their new inserted tooth edger. Here is what I came up with. I am a little reluctant to increase the tooth bite much more with only 60 HP on the arbor. How does this look?? Any ideas ?? Thanks

saw = 25" diameter (given)
plate = .148" (given)
bits are 5/32" ( would rather have used 1/4" bits but they are going to get really hard to get very soon)
feed speed = 180 fpm
saw rpm = 1400 (given)
number of teeth = 21
max depth of cut = 6"
min. depth of cut = 1"
horsepower = 60 (given)
number of saws in cut at any one time = 3
tooth bite = .073
side clearance = .082

What type of wood are you cutting - hardwood or softwood?

Actually, a larger bite reduces hp. Think of it the other way - if you're cutting fine sawdust it takes a lot of energy to break the wood into little bits.

Also, torque is the other factor to consider.
