Dspiae drill bits are far to brittle and snap if you look at them weird.
I have had some drill bits several years and not broken them, those from Dspiae I went through a box in an afternoon. Three broke finding centre!

Hi what size the shank is on these drill bits
[HEADING=2]Tungsten Steel Drill Bit DSPIAE DB-01-20[/HEADING]

I replied to your email, didn’t you get it? They are 3.175mm, as people have said, tungsten is much softer than steel and they do break easy

Must admit I just buy replacements as job lots ten at a time and use the micro box to hold them. Don’t break many, even the very small ones , but I don’t use them powered. I just use them manually powered in a hand Chuck. I think powered mini drills are designed to break drills and sell more drills :upside: In sheet stock I sometimes just drill a pilot hole and open it to size using a five sided tapered broach.

I agree, I went daft at the comps and bought myself an archemedes drill not realising you need two hands to use it, and there go all the drills....

I have about half a dozen pin chucks these days, picked up at various places over the years. I use two hands on them, left one supports the pin Chuck by placing the index finger on the top, and the right one does the twiddling. Slower than a power drill, but more accurate and less costly. Still break drills occasionally, but usually 0.5 and smaller.
