Good question... Unfortunately I can't tell you what the differences are
. Used Apple for few arrows but got better results with a Bosh angle grinder in some 3rd party holder. The Apple seemed to be just ok but the whole saw is just to large for my workshop and I smoked a 220V to 110V adapter so I gave up. Another thing, the 5000rpm saws aren't good for film coated carbon arrows. Tends to split it if you don't take care.
Forgot to mention... It took 55$ to buy the holder, grinder and 3 different wheels
