I'd read on another thread that someone bought a spot welding drill bit for $40.
These sort of things can be hard to find at times eg Sydney Tools guy today ...."what are they?"
I bought two today at Graham Macdonald Supplies
1/127 Magowan Rd Girraween 02-9636 2284
I paid $22 for a 6mm one and $27 for an 8mm one. The larger one at least is German.
- no connection, just happy to find a source.

Hi
Make sure you use a good cutting oil with them. I've used a fish oil style one and one from Wurth, both in spray cans.

"Make sure you use a good cutting oil with them. I've used a fish oil style one and one from Wurth, both in spray cans."
Oh yes - that was the rest of the purchase yesterday. $14.50 a can
Definitely use good quality ones, and definitely use a cutting oil. Industrial consumable supplies and Automotive paint and panel suppliers should be able to hook you up with them. The panel supplies has to be a proper place, not just your rattle can and neons supplier.
Yep - this place is a tools specialist. I bought a cobalt drill bit off them for a job on the boat a few years back too - that one was a lot dearer.
Here's the results with the spot welding drill.
Hi
Looks much better that doing it "Swiss Cheese style"

post a piccy of the drill bit, why so dear are they tool steel or something?

I hadn't thought of it as dear actually - I thought it was cheap - $27 compared to the $40 elsewhere. Not sure of the materials - but that little nib must be as hard as ... I've done right across the base of the windscreen with that bit - and its as sharp now as when I started. I used cutting oil too.
I'll have to re-do the shots I took of the results of this drill compared with the ordinary drill I used earlier. The difference is less distortion, less damage to the backing piece and a lot easier and faster to use.
Cheers, I see, it just cuts the top piece through and not both.
Would make it much easier to put the new piece on.
Lots to learn on this forum! Must be tool steel to keep that sharp/hard.
