Anyone know where I can buy tapered jet reamers, maybe a set of 5 or 6 that range between from 2.00mm to 3.00mm (yes to open needle-jets :-) ), style as per the ones in this link: https://www.misterworker.com/en/kukko/nozzle-reamers-set-12-pcs/59063.html?gmc_currency=8&SubmitCountry=AU&gclid=Cj0KCQjwgLOiBhC7ARIsAIeetVAJy33u6HZdY3VViFi2whChlZCXy1f5LJhZY4fv_kYDTA_Fm-fYAbcaAnJ7EALw_wcB But up to 3.00mm, or maybe 2.80mm

Try Capital Cutting Tools in Hamilton Victoria (Email: [email protected]), they have Chucking reamers up from 2.0mm (H7) in 0.1mm increments for about $22 ea + GST. They may even do more specific sizes if you ask ie 0.05 increments.

I use drills. I have 0.3mm to 2.5mm in .05mm steps and bigger sizes in "Number" drills. Number drill sizes https://littlemachineshop.com/reference/numberdrillsize.php
I like the drills as they are a fixed size where the tapered reamers will open things out but difficult to control the size.
The mm sizes match Mikuni pilot jets as they are in mm's, meaning a #35 pilot is .35mm etc. Main jet are more difficult as they are in flow rate but most of the jet drilling I do is for Methanol so the .05mm steps are more than close enough.

Ya, twist drill go up to 5.00 mm in .05 mm (0.002") increments and brass is the easiest material.
