Burrs and drill bits

[pearlescence]

These days, unless you have a cheap source, I can buy drills direct from the manufacturer abroad in bulk far cheaper than I could buy needles here - plus the saving in man-hours to convert them...

That's really interesting James......I don't remember seeing that before, how long did it used to take you to make a drill bit?

Thanks James, that is interesting. Will have a go.

pearlescence, can you tell me where you get your drill bits from abroad?

Cheers

Alibaba.com and do a search.

Just picked up this thread because I was using a setting burr when it started 'screaming' & nearly deafened me!
I cleaned them, made sure they were lubricated, varied the speeds but couldn't get to the bottom of it.
Does anyone know what causes this dreadful noise?
