    Default Reamers

    After any recommendations for a 8 mm reamer?
    To ream a mild steel bush approximately 15 mm deep.
    Having never ever done this I’m open to guidance
    Do I go cheap from EBay China ?
    A spiral ream,hand or machine driven(lathe Hercus 9 inch).
    I’m wanting to make a small wood work marking gauge.
    Using an 8 mm harden ground shaft.

    Cheers Matt

    Hi Matt,

    All my reamers are cheap Chinese ones.

    I made a marking out gauge some time ago. I used a carbide stylus in mine. Would be interested to see yours.

    Thanks Baron,
    That’s good to know, I might grap a cheap one to start with, an see how I go.

    My gauge will be another long term project, don’t we all have them.
    As unfortunately my circumstances have changed a bit so shed time will be limited for a bit.
    But there’s always planning an window shopping to be had.

    Cheers Matt.

    ebay China, aliexpress etc will be OK

    A straight flute reamer will be fine for the simple reaming job you want to do now, a spiral flute reamer is more versatile, plenty of reading on the interweb.

    Machine reaming is always going to be more consistent than hand reaming.

    Thanks Bob,
    I did do a little bit of research the other day,
    But I have a lot more faith in the information I get here.

    Cheers Matt

    Go for any that you can afford, if you decide to use the lathe, then make sure you are only taking out/cutting with the reamer, just the last few thous.

    Bore it as close as you can and just use the reamer to be sure of the exact size hole your after.

    One thing you should NEVER do with a reamer, is use reverse on the lathe chuck to take the reamer out, just leave the lathe in forward and gently remove/draw back the tail-stock by hand.
    Reason is - if you reverse the chuck whilst the reamer is still in the job, then you surely can and at some time will, take the cutting edges of the reamer.

    Same when using a reamer by hand, never twist it backwards to the cutting edges.

    If you never twist it backwards then the reamer will be as sharp as for ages.
    Never store them loose in a draw and allow them to bump each other or anything else that's hard, think of chips being taken out of the cutting edges.

    I've bought several reamers second hand from ebay. Reamers are not the sort of tool that the average handyman picks up so are likely to be in reasonable condition, even if a little grubby and not quite as sharp as they could be. If this is just a one off, then that may be a way to go (I might even have a 8mm that you can borrow, but then there is postage...).

    Thanks for all the advice so far everyone.

    I definitely won’t be running the cutting edges backwards an will keep them on the shelf in the little plastic boxes.
    Michael thank you for the offer, but I’m now waiting on one from eBay.
    Which would probably be the same as postage in Oz anyway lol.

    Cheers Matt

    Very much agree.
    Hand reaming might work, but in my experience is that it's easy to get a "rounded polygon" shaped hole, not necessarily noticeable.

    Adjustable reamers are great for the occasion where you're stuck without a particular size or when you need to take a smidgeon out of a bush that has shrunk when installed after you got the fit wrong, but apart from that I never use them. I've got a set that came from my grandfather - I think I've used them maybe 3 times in the last 15 years or so...
    Also only good for through holes due to the adjustment nut.

    IMO - if you've already got fixed size reamers then by all means grab a set of those to have on hand to get you out of trouble, but otherwise just pick up some cheap fixed size ones. I got a cheap set recently (possibly from Banggood) that I think were only about $20 for the main sizes from 3-12mm.

    Hi Freddie,

    I have and use adjustable reamers ! But they have one major downside, the fact that they can be adjusted means that you have to be careful only to alter them in very tiny amounts or they will grab and the blades will break. All the normal rules apply ! And like other cutting tools used inside bores, plenty of cutting compound, tapping compound like Temaxol and the like works well, just plain oil will do if you don't have anything else
    Best Regards:
    Baron J.
