RE: Drilling Blanking Plates?

["Dave McLaughlin" <dave_mclaughlin@xxxxxxxxxxxxx>]

These are superb for steel but you need to use a pillar drill and have
the
part you are drilling fixed otherwise these will move your plate around as
you try to start it.



They do however make a very neat hole.

Hello Simon

Yes they sound great but how did you ensure that the core drill was
centered on the location of the hole?

Thanks

Tracey

I drilled some recently, and they are difficult to drill without chipping.
However, I then borrowed a pillar drill, which makes it really easy to
drill straight, and I also got the lend of some core drill bits that look
like these:

They made a perfect hole every time, and I'd recommend trying to get your
hands on one.
