X-Head Porting....
Ok. Now I'm starting to get pissed... these burrs are 15-20 dollars each... bent one last week, one broke last week. Today put one in the grinder and it instantly bent when I first pressed the foot pedal, tried again and same thing to the 2nd one. Thats 4 burrs and roughly 60 bucks down the drain. I tried to shorten one and its still not spinning straight in the regular hand drill...
