Cast brass fittings

(1/1)

The Old Fart:
I need to drill some brass castings, but they are very hard, any ideas?

Mark T:
I use cobalt tipped drills which seem to go through anything. They are not to expensive either and last a lot longer than jobber drill bits

The Old Fart:
Thank you, I'll order some.

The Old Fart:
Cobalt drill bit worked a treat, and they weren't too expensive.

Mark T:
That’s great news  :-))  try them in a bit of stainless steel they’re fantastic!
