I used to do that sort of thing regularly, when I worked for a living.

A cobalt drill would perform better than "my" hss regrinds used to do!  :ThumbsUp:

Don't go deeper than the depth of the point angle. There's no side relief on a spotting drill........

Thanks guys, I've been wondering the same thing and I'm just getting ready to place an Enco order.
I think they are even on sale.

They possibly do, Marv. But, I've never come across them......  :-\

Considering the differences between our languages, it's possible that they're known by an entirely different name.

As said, they're not easy to get over here Marv.

I found this supplier a little while ago but look at the price!

 :headscratch: - a good quality 3-flute 90o countersink bit might also do the job...:
Sort of like this one: http://www.somta.co.za/cat/761.htm
Needs a bit of clearance for the tip though, so you might have to use a small slot mill to cut that.  Or even a slitting saw with the part in another  set-up.

Kind regards, Arnold
Building an engine takes Patience, Planning, Preparation and Machining.
Procrastination is nearly the same, but it precludes machining.
Thus, an engine will only be built once the procrastination stops and the machining begins!

I used a cheap countersink to cut this vee in the peatol, but as Arnold says, its best to cut a narrow slot with a slot drill/hacksaw/slitting saw etc.


I even cut a larger vee with a 1/2 dia. countersink, and although i cabbaged the teeth (forgot to change speeds when i swopped from small slot to countersink) it still produced a decent job.
