Tapping -- How to's and How not to's....

Arc Euro Trade also have small drill packs in 0.1 mm increments these ones are TiN coated but a little dearer
I have the 1-10mm set and they are not bad drills

This is an excellent reference: http://littlemachineshop.com/Reference/TapDrillSizes.pdf. It covers metric and Imperial screw and drill sizes, and also allows for the type of material being worked.

We can revisit it if you like, I only opened the door.

Yes, I use my TapMatic with HSS taps all the time. The main thing it to match the tapping rotational speed properly.

I'm looking at maybe purchasing a 50TC/DC unit. If I wanted to tap M6 in aluminium to a depth of 2", would this device do the job - and what sort of speed will it tap at? The website blurb says it has a "re-entry cushion" to prevent cross-threading; which suggests to me I can plunge multiple times (maybe with taper, 2nd & plug?) into the same hole & it will find the threads & augment them, rather than chewing a new set out of the old...
e.g. here's a utoob video which seems to suggest a tapmatic will scorch through metal:
Thoughts?
