It's not my only guide, but value for money wise most modellers don't need expensive high precision drills to drill holes in plastic models. The microbox drills and other like them are perfectly adequate for the job.

@Dave Swindell many thanks for the recommendation! I'd seen those at my local (Jadlam), will pick up a set next time I'm there

Aluminum makes lots of little flakes and shavings when it's milled. I used to work at a machine shop. I hated that stuff, too! It gets everywhere!

Not at those prices I won't. 10 Euro's for one drill? I can get the microbox set I linked above for that, or a pack of 10 replacement bits.

Surprised no one has mentioned the Tamiya bits? For small sizes I find them great as they have really accurate but short threads and sturdy shank. The cutting portion is only 4 or 5mm long so difficult to break and while I’ve gone through boxes of pcb bits (and still find them good for bits about 1mm and up ) I now have the full set of Tamiya bits from 0.2mm to 1mm. Not cheap but never had to replace any so actually good value. Also don’t have to try and dig broken pcb bits out of my models

I have used two sets from Trumpeter Master Tools for several years, #09954 and #09955. I have managed to break only the 0.3mm, wasn't careful enough. I don't drill resin, just polystyrene which is softer, so I don't how long lasting they would be if used to drill resin parts.

lot of industrial cutting and drilling uses/used cutting oils or other lubricants to ease the process, and also cool the work piece I have long since accepted that small 0.3mm/80 drill bits will not survive long.

I have been modelling for years and constantly have to keep buying new drills......only break .5 and below - all the time(at least 30 years plus).  I have tried all makes of drills, diamond, etc, you mention it, I have used/tried it......anything below .5 is going to eventually break, if it doesnt, it either goes blunt or bent........impossible to see the tips to resharpen, even purchased jewelry drills.....tried everything.  You just have to accept, those small drills have a limited shelf life........I just write off to various Jewelry  shops and buy bulk drills.....10 x .5   - 10 x .4 -   10 x .3................have many duplicates now of the sizes that do not break......being so fine, they are a welcome prize for the carpet monster......I have a special mains miniature vacu-cleaner, just to hoover the carpet about once per month.

I think I've only ever broken the two smaller sizes in my set, and like you I've bought packets of 10 so as to have spares in stock. Shesto do the sets and packs of 10 individual sizes, so you have a choice of what suits you best. Personally, I like the set in the handy storage box, and I'd recommend it to anyone looking for a general purpose set of small drills, however I've only ever bought two sets, one for the home workshop and another for a travelling toolbox.

I currently use PCB drills (bought off Ebay cheap) however, I find them incredibly brittle and the thread is very, very aggressive, which often means the drill bits bite and snap (especially in resin).

Someone on the RPF forum puts the insulation from electrical wire around the shank of their micro drill bits. The effect is some slight give in the shank where it's held in the chuck/collet and where it tends to snap, and not one has broken since he started doing it.

Like every other Harvey made table saw machine, the ALPHA HW110S-36P and 52P are designed and engineered with unsurpassed quality and excellent performance.

Going on from above. A good lubricant for cutting plastic is water believe it or not. However the sort of drilling we do in plastic is more of a case that the drill bit is rotated by hand rather by machine. so heat should be minimal.

I remember talking to my dad about small drill bits. He worked in light engineering all his life and must have drilled millions of holes. Small drill bits in metal didn't last long for all sorts of reason, but largely because they were so small and relatively fragile despite whatever they were made out off. He reckoned that the really small bits in plastic suffered because plastics are relatively good insulators of heat, and so the area around the bit heats up. In some cases the plastic will soften and foul the bit, thus making it more likely to break. Also plastics may not be a consistent density. A

You're right, they are good, and also easy to change, as the base is thicker. I did something stupid and broke the 0.2mm, but 0.3mm is still going strong.

I got fed up breaking the cheapo drill bits but now I use Proxxon drill bits such as these Proxxon 28255 Diamond Twist Drill Bits 0.8 and 1.2 mm. Not cheap but worth it in the long run .

I've given up on buying drill sets, as like others I keep breaking the finer bits - or the carpet monster eats them. Instead I buy packets of 10 HSS bits off Amazon.

Sadly, those PCB drills are not at all suitable to hand drill as they're far too brittle. I had a set and they snapped with the least bending. I stick with regular HSS sets.
