post processing drill bits

According to the instructions to upgrade the MK3S to the + version I need the following:

[Twist drill bits, ideally with a flat head, but those aren't easy to find. The lower the angle on the bit's head the better. For printed parts you need two sizes: 8.1 mm / 0.3-inch drill bit (or slightly bigger, but not smaller) 3 mm / 0.12-inch drill bit (or slightly bigger, but not smaller)]

What drill bits are people using in the USA?  Why are these so difficult to come by? I have a full SAE drill bit set, which ones am I supposed to use?

Thanks!

I am not aware of that requirement but perhaps this is a recent change.  Prusa usually supply all necessary tools...

Please provide a link to the instructions you are following.

Cheerio,

many things are becoming increasingly difficult, or more expensive to find here in the US.

 

Good Luck

You can always grind the point off...

Ah yes, I'd forgotten. I have a wide range of similar tools so just reaching for the item doesn't stick in the memory...  When I last printed a replacement X idler housing I used a reamer.

If you cant get conventional flat-point drill bits try an auger style wood bit - there will be a little spike at the end which can be snapped or ground off.

Cheerio,
