There are some really naff centre drills around, regular PITA when they snap off. I got some cheap, centred 2 holes then lobbed the lot straight in the bin.
Caveat emptor, I've gone back to Plan A, don't use anything but Dormer :D

Dormer aren't what they used to be...I picked up a set of drills, made in Mexico of all places. Drilled a hole in a piece of 1/4" mild steel and managed to snap a brand new 10mm drill bit straight in half with just the torque from a cordless drill and in a hand tightened QR chuck too!
That's the first time I've ever managed to break a drill over about 4mm in diameter!
Complete carp!
