Adam:  Know this!  It may cut FR4 (G10, etc.) OK, if the blade is properly 
sharp and PERFECTLY-concentric, but once you cut 2" of the stuff, even if it 
will continue to "do good" on FR4, it is NO good for woodworking (esp. 
plywood) until diamond-sharpened, again!  

Same with a steel bandsaw blade.  A BS will cut FR4 "just fine" for a time, 
but after only 1" of cut, it is RUINED for further woodworking!
