Different Nozzle Sizes experiment (Page 1 of 2)

Would be nice to have a .2 to .5mm Drill-bit set now, But ......

yes, I had found a set on eBay, but it cost about as much a whole Pile of nozzles. LOL
I may order the set Anyway the bits will be a good thing to have for Cleaning nozzles.
And for making sure the nozzles are the size they are supposed to be.

I ordered a set of 10 Bits for $16. total,
2 each of 5 sizes (.2 thru .6mm)
they are tungsten-carbide also.

I had really not planed to try the .2mm but do want to try the .3 and .5mm.
.2mm Looks way too Small to me.

BTW: Gotta Love Makerbot ! without them, we would not have this wonderful CTC printer

Now I'll need to Print some Handle/Holders for those Drill-bits !
Different color for each size would be Great !

I'm curious what type of testing was done to determine that .4mm nozzles is the Best?
Has anyone heard who and where decided that size was to be sold with these printers ?
I assume it was someone at Makerbot ?
Or did Makerbot Copy someone Else ?

I found Handle for bits at Thingiverse , with 1/8" hole, I'll be printing Those tomorrow

Carl,
You should start another thread about that conversion, if you do it.
That would be interesting to follow your progress on that project .

I've got the first drill-bit Handle printing now,
Doing it in Purple color !

Using the drill-bits as Gauges, I determined that the right-Nozzle that came with printer is actually a .3mm nozzle, not the .4mm they say they are.

I tried printing with the new .4mm nozzle and it is Excessive .
(Just not the smooth lines like the .3)
I was really surprised at the difference, of .3 and .4mm, made in quality of object !

The .2mm looks Way too small,
so I will be using .3mm size from now on.

Good idea, but the slicer setting was always .4 , even when using the .3,
so don't think slicer setting would cause it to be excessive when using a real .4 ?

Maybe it would not look excessive to most people,
I've just been accustomed to, and appreciate, the look of the .3 . LOL

Warning: those Little tungsten-carbide Drill-bits are Not good for drilling out Nozzles,
Only good as size Gauges.
They Break  Very Easy !

thats because China dont even know what Tungsten Carbide is much less make drill bits with it LOL.

learned that 30 years ago. Chinas so called high speed steel bits also NOT. they will untwist in wood lmao.

buy real made in USA drill bits or dont waste your money at all. Anderson Forester is only quality made tiny number gauge drill bits like used for gas orifices (orifices are only brass by the way so use great care not to ruin them)

if an orifice has a burr or any tiny flaw it is no longer an orifice. and when you "clean" them with tweezers you are actually reaming them out with a bevel which also ruins them.

an Orifice (especially on a 3D printer) has microscopic dimensions both inside and out. which must be exact the inside bevel/taper to direct flow for needed performance. the smooth even hole (often with tiny crown to prevent spider webs) then the correct amount of flat face for smoothing molten filament. any China drill bits I find in my drill index get 'recycled in file 13' where they belong as they have cost me many times what a good bit is just in time and damage to items being drilled/redrilled/replaced or injury when they break and stab user. I never buy bits on ebay or at Harbor fright. after making my living for over 40 year career with tools. I know better than to rely on El Cheapo brands
