Drilling out Broken Bolts and Screws

DRILLING OUT BROKEN BOLTS

I have found that when drilling out broken bolts, screws and easy-outs, DrillBitWarehouse.com has a great set of left handed drill bits. A left handed drill bit has a reverse flute so all you do is put it in a hand drill in reverse and it just makes drilling out bolts so much easier. Sometimes I use a solid carbide rotory burr, if the broken bolt is made out of super hard steel. With a micro-grain burr it actually grinds through it and drills it out. I bought a Set of four extra long carbide burrs and they really come in handy when a long reach is needed.
