Do I need the Q.Max allen keys or will standard ones fit?

Cheers

They use Metric Hex keys

Lawson HIS used to be reasonable for them and a good range.
Not sure how prices compare now...

Cheers just ordered some from PVR direct - prices seem okay

I've cut 3mm on occasions but its mostly stainless i do.

Langy, what gauge alluminium could you do with the Qmax? I've got a feeling it'll tend "clog" a bit. I've used them before on stainless but they weren't mine.

Anybody tried these?

This is a 1.5"dimple in 1.6mm stainless

I have bought Qmax from Buck & Hickman but as i said most of mine are quite old but still sharp, I make my own dimple dies from ally or steel, heres a few pics that may explain.

Ally bar stock

Female die

Male die

They go together very much like a Qmax cutter

Hope this helps.

Langy - by dimple die do you mean swage the engs of the hole in for strength & smoothness? If so that's exactly what I'm planning on doing - so cutting holes in 3mm steel is not even on the radar - I just need them for up to 1.5mm mild steel. Maybe 2mm ally at a push.

The other benefit is I can buy the Q max cutters in the same size as the swage tools.

Do you need to lubricate them at all (the Q max cutters?)

And any where you know that is cheap to buy them?

Thanks again fella!

Yep Langy - that's EXACTLY what I'm wanting mine for.

Cheers fella!
