    It was some time ago (more than a decade) but when I looked around for a 1-13mm set in 0.1mm increments I could not find any in Perth.
    The only 1-13 mm set I could find were in 0.5mm increments.

    I ended up buying one set 1-6 mm set with 0.1mm increments from McJing, and a separate second set of 6 - 10 mm with 0.1mm on ebay.
    Recently I bought a 0.5 to 3 mm set in 0.1mm increments with 10 bits in each size from ebay.
    Even though they were cheap sets I am surprised how long they have lasted. The main users have long since broken etc and been replaced with decent bits.

    Here is a set of 1-10 in 0.1 mm plus a few more up to 13mm in M2

    Heres the same in M35 - make sure you are sitting down before you check out the prices

    Hi Bob

    Thanks for the write up, and yes Ouch those prices are steep.

    C-47 (I think you know him) mentioned a place in the Bassendean area had a set for some reasonable $$, he could not remember the name and I also googled for it. One possible company that came up on Google closed around 5 years ago.

    If nothing comes up here I think I'll have to go eBay route as you suggested.

    Cheers

    I bought 1-6mm and 6-10mm drill sets in 0.1mm steps at McJing in Sydney - see https://mcjing.com.au/categorybrowse...?categoryid=53 - scroll down the page to find Drill Sets. Not incredibly cheap, but affordable for what they are. Quality seems to be OK.

    They suit my needs. I don't use them for rough or general work, only for opening out pre-drilled holes to a to a size I am looking for, when reaming accuracy is not needed.

    Cheers,
    Bill

    Venables In Malaga and a couple of other places used to sell individual 0.1 mm bits and was where I got some replacements from a few years back but when I visited last year Venables no longer stock all sizes.

    Do you need the 0.1mm steps? It might be easier/ cheaper to get a set of number drills.

    A set of number drills might be ok,

    With my current poor selection of drills, 1/32 or 1mm steps, every time I need to tap a hole I never seem to have a drill of the correct size, and that's what I'm really trying to fix.

    I have also bought the 1-6 and 6-10mm in .1mm rises as WCD has done from McJings. Good value for money, and their reputation for quick delivery is well deserved.

    Contact General tools here in Adelaide - they are an industrial supplier and should be able to source what you want. Bear in mind that it will be good quality stuff, so will cost.
    However, if it is just for tapping sizes, industrial suppliers (and several fastener chains) do sell individual drills. So if you are tapping M3, M4, M5, M6, M8, M10 and M12, that is only 7 hole sizes - even buying 2 off of each sized tapping drill should not cost a fortune. The issue with buying a set in 0.1mm steps is that most won't get used - bit of a waste really.

    I just replaced a broken 3.7mm with a Sutton one. Price.... an eye watering $15.00.

    I am over chinese mild steel (claimed to be HSS) drills and other tools in general.

    One of then most useful things about the 0.1mm sets is to have on hand the 0.1 mm "over" and "under" recommended size bits required for tapping so that in thinner softer sheet material (like 3mm Al, brass or plastic) I can make the thread a slightly tighter fit, and if necessary VV in thicker harder materials. In the case of the latter I've broken a few less taps but just using that 0.1mm larger hole.

    In a similar fashion for non critical load work, if the required drill bit is missing which in my case is almost inevitably (muggins law of drill bits, the one you need is always the one that's missing) I then use the closest 0.1 mm bit and it usually makes little difference.

    I've also found I'm tapping imperials far more than I thought I would (about half as often as metrics) so combined with all of the above I'm really using my cheap set way more than I thought I would.

    I've also been recently tapping a lot of plastics for 2 and 2.5mm screws which is why I bought an extra set (10 drills per size) for <3mm operations. If I drop one of these small suckers my shed I can only rarely find it.

    By the time all these are added up its close to ~50 drill sizes so it is worth getting a 0.1mm set as a starter. I've replaced almost all of the bits for the standard sizes several times over in some cases.

    Hi HeavyMetal,
    First up, welcome to the Forum.

    If it is only a matter of drill sizes for standard taps it not a big deal you may not need a whole set.

    If you are beginning, cost is a concern so it helps to buy just the basics and add to the set only when you need it.

    For instance I use only metric.
    I have a block marked and drilled for the sizes I use, 3mm through to 12 mm.

    The M prefix is the Tap diameter and the suffix is the standard tap drill diameter.
    M3 -2.5mm, M4- 3.3mm, M4.5 - 3.7, M5-4.2mm , M6 - 5mm, M7 - 6mm, M8 - 6.8mm, M9 -7.8mm
    M10 - 8.5mm and M12 - 10.2mm. Thats a basic set suitable for a new DIY metalworker.

    Those are fitted to the block with the tap/s ie full depth tap ,(intermediate and starter - if you are using them ) and each is marked appropriately for that diameter.

    The sytem saves a bunch of time in that you are not looking for the drill and tap chart,then searching out the right drill diameter. It all there ready to go.

    If I can remember to replace the drill and the tap back in its respective place it works well.

    Welcome again,
    Grahame

    That's pretty expensive. We pay more like $5 at work.
    I have never bought from them, but this company has pretty good pricing.

    I wouldn't bother with .1 increments over about 4mm. I work in a machine shop and we only have sets in .5mm and 1/64th increments*. normally if you don't have a odd metric size like 10.2mm to tap a m12 hole there is a imperial drill that is close like 13/32(10.31mm). If money is tight you are better off with fewer good quality drills than lots of poor quality ones.

    *Note: we specialize in large parts and rarely tap anything smaller than M4, if your threading really small holes my comments may be invalid.

    Default Amos drill bits

    I have spoken to the owner of the above company about his drill bits be has made, I forget where he said but he is very knowledgable about how they are made.
    He is very approachable about his products.
    His company sells them direct at a much cheaper price than you can get similar drill bits.
    I haven't purchased any yet, I phoned him about stub drill bits but he doesn't make them.

    I don't have any monetary interest in this company and only posting for the interest of others.
    If someone buys the bits please let me know how they go.
