    I like to buy the cheapest possible indexable insert tooling for my lathe as I possibly can, for the price they are worth the gamble.

    I must have over 20 various tools now and have never had an issue, the quality has always been perfectly good and serviceable.

    Until now...the torx driver supplied is poor even by Chinese standards. :D

    I wondered if it was possibly just in the wrong way...it was...:laughing:

    It's not that it's in the wrong way round. It's just that they didn't machine the second end :D

    You obviously haven't looked at the screw head on the tool, probably find it's got no splines and the tool would have fitted perfectly :clapping::clapping:

    I've not had a problem with a torx bit, so far. But I do buy from APT. Remember that they don't need to be done up too tightly.

    maybe they thought the torx end was for gripping the plastic:D

    That socket is more expensive than the boring bar in question :D

    I have several sets similar to this.
    One in the kitchen. One in the van and one in the garage.
    A lot less fiddly to fit a new insert that the keys they supply.

    I have been quite happy with all my cheap tool holders - obviously I’ve not had the issue posted.

    They’re so cheap it’s possible to have every size you want and multiples to avoid changing inserts which are just too small to be easy.

    Yep, the most expensive part of the cheap insert holders is buying more toolholders to house them all!

    aint that the truth
     
  12. I bought an indexable holder and 10 inserts from ebay. They either go blunt very quickly if I don't take a good cut, or they chip off when I take a reasonable cut because it's dug in and ruins what I'm making. I'm thinking of going back to HSS tools. Perhaps I'm doing something wrong.

    Rubbish tips I think.

    I buy cheap toolholders but never use the tips they sometimes come with, only decent ones which are not particularly cheap but well worth it. I'm sure that some of the cheap inserts are OK but it's obviously a lottery.

    I find good tips can give a mirror like finish on good materials - though you often have to take a bit of a cut, they don't always like taking a couple of thou off - and they stay sharp for a good while, generally I knacker mine by turning down a hardened shaft rather than normal wear. I don't bother with HSS unless it's a specialist shaped tool that needs grinding for a special job - I want to spend my time removing metal and making finished parts, not sharpening HSS to watch it disappear before my eyes as soon as I try to take a decent cut...

    I bought a few of the Chinese indexable tools a long time ago from Banggood, used a few & have been impressed by all so far. The supplied inserts have been mostly good, only had one bad one that broke on first use.

    I've never been able to use HSS parting tools on my Myford ML7, too much chatter & noise. Last week I took the plunge & tried the Chinese one from my set - it worked perfectly, no noise or chatter, it just parted the item off with no fuss! :D

  15. That's interesting. I've never had any luck with parting on my ML7, but it did have a very very hard life before I acquired it, for free. It hadn't seen an oil can for decades. It's got broken gear teeth and excessive slack and wear in the slides and I'm amazed at the finish I get. I just wish I knew how I could get the chuck to work without a run out of about 5 thou. Anything I make has to be carefully put back in the chuck and turned in the jaws several times before It runs true again.

    I must be lucky with parting off on my tiny hobbymat lathe, it's something Ive not had issues with and have parted off 60mm dia steel bar on it.

    [​IMG]

    I use a hss blade from chronos, its the second one on the link below 2mm x 10mm blade with 5/6mm square shank holder.

    https://www.chronos.ltd.uk/cgi-bin/...th-Chipbreaker-Blade--5--cobalt-.html#a392675

    I do think that the blade is narrow (2mm wide) and the "T" section of the blade reduces friction and together they reduce the load on the lathe when parting off.

    I have to say the little Drummond M copes with carbide parting tips very well, I have not been tempted to try HSS but who knows they may work just as well.
