It’s not about the size of the shaft but what it’s used for.

I'm lost, but cary on.
Not nearly as cool and no pix yet, but i finally broke down and got a few cheap diamond files. I have no idea how I've managed to get by without them for so long, the ability to file any hard material is a game changer for me. They work great on stainless which will eat a regular file up, and it works reallyyyyyy well for touching up cutting tools, especially drill bits. I very seldom have access to a bench grinder, and I'm to the point where i can't see it as well, so by using a diamond file to finish the sharpening i can get the angles and chisel perfect, and can even cut in the self centering pilot notches/split point or whatever it's called. I even hit a hole saw and it cuts like new again, couple strokes a tooth and it's cutting like butter again. I'm hoping to use it to lightly touch up tungsten too, haven't gotten to test that yet but imagine it'll work perfectly.

I forget which thread i started talking about making d bits for drilling and stuff, so i figured i would just put it here. Ive been playing with them a bit lately and have learned a few pointers that really help. Cutting tools work by leading with a cutting suface, but will rub and not cut if the back of the bit is interferring, which is solved by adding a bit of clearance so it cuts well. That makes a huge difference, as does shaping the point like a fly cutter, flattened and leading with 1 end. If you needed a flat bottomed hole like you were recessing a bolt, a full sized version (not tapered) can be used as an endmill. I haven't tried it yet but i also imagine that cutting a small groove along the cutting edge so it has a positive cutting angle would also make it cut better, I'll see how that does sometime and update that later. I also learned they make these bits for sheet metal too, unlike a twist bit these won't self feed and jam (because it's a straight flute cutter), so you're way less likely to damage the workpiece or yourself when using them. All in all a really handy trick to know with many different applications.
