Grinding Turning and Facing Tools for the Lathe

In this video I discuss cutter geometry of the turning and facing tool for the lathe and do a demonstration on how to grind them.

    teaching at its best. this is what i call learning things practically.
    really appreciate your efforts. thanks ………..keep uploading

    what type of shape should you make for cutting a perfect square shoulder
    like on the inside of a receiver??

    Hi Tom. I just watched this one again and it is still very good. I am sure
    many will enjoy the benefits of your informative, well organized and
    personable presentations long into the future. I have for sure. I think off
    and on about that nice knurling tool you made. I know you are busy and it
    takes a lot of time to make a video. However, I am looking at this video
    having received 16,471 views and would like to point out how many have
    shared in your knowledge. Even what you have out now is enough for two
    teachers and you must not take it that I have unfulfilled expectations. I
    am very happy with what you have let us learn from you. Hope you are well
    and happy.
    Best regards,

    You could make a fortune selling these tools. I for one would buy several
    facing and turning tools. My expertise in tool grinding is lacking. I took
    your advice and bought some stock metal to practice on, but …well you
    know. I’m using a 7×12 mini lathe and it is a challenge. This is all new to
    me and I just can’t get enough. Thanks Tom for you skill, patience and
    generosity in making these videos. I printed out the right hand facing tool
    on your site and will give that a try tomorrow. I have a variable speed 8
    inch grinder. What speed should I be using. Where can I buy a facing tool
    all ready ground. I buy most of my stuff from Little machine shop.

    Very informative video, Tom! Probably the best video on Grinding tools that
    I have seen. Thanks for mentioning the grit of each grinding wheel. I have
    been wondering about that.

    As a student I am expected to know how to sharpen HSS even though I mainly
    use carbide in industry. Up until now I have not seen a good technique
    demonstrated. Thank you so much for this.

    Hi Tom. Started my trade ( Fitting/turning Diesel Fitter) 35 yrs ago.
    Changed jobs regretfully near 30 yrs ago. Not on tools but always had
    a well equipped garage. Bought a 930mm bed lathe a few yrs ago and was
    frustrated coz I forgot so much. Your videos have been an amazing help and
    inspiration on so many tips that only a person of your experience has. The
    way you put it across is also spot on even for an oldie like me. Ground my
    first 1/2″ HSS tool in 30yrs and cut beautifully. Bit of a rant but vey
    grateful and appreciative of your help. Kevin

    At 10.10, I would have put the “angle tool” on the bench. I think
    controlling the HSS bar is easier without having to carry other stuff at
    the same time. Multi-tasking isn’t for everyone – LOL, and they shouldn’t
    be tempted to do like You…:)

  9. RedlineRennsport says:

    Hi Tom. Good stuff as always. I wonder if a companion video on stoning the
    tool to completion might be nice? Sharing your tool choices and techniques
    for that, as well as to why it is benficial might put a perfect finish on
    the subject.

    another excellent video, very well done.

    Hi Tom,
    Really great videos! Please keep up the great work. I instruct shop at
    the local college and was wondering about your choice of a 90 degree angle
    between your side cutting edge and the front cutting angle. At the college
    we always make the students produce an 80 degree maximum angle at the same
    location. This gives up a bit of strength but it does allow the tool bit
    to now turn diameters and also face off the shoulder all in one setup. I
    like to hear your thoughts…

    question! could you do a quality job with a dremel and stone? i prefer it
    over bench. especially for small work

  14. Carlos Vanquish says:

    hi good day thanks for a informative and interesting video I thought you
    had a bean stork in you garden . and you bought the same beans jack bought

  15. DomManInT1 says:

    It is funny the ideas that people get about grinding tools and then they
    try to teach those same ideas.

    That’s the wonderful thing about YouTube . What ever you want to know about
    its there ! Thank you for posting Tom .

    THANKS so MUCH! I have been searching for while to get some quick answers.
    I have a small metal lathe, that I use for wood. Occasionally I want to use
    it for metal to make just a little replacement part, or a self engineered
    piece, and metal is enough different than metal, so that I need help. I
    don’t want to do it for a living, or for direct profit, so I can’t justify
    long, expensive, time consuming classes. This is the best quick reference
    information I have gotten! I think I might be able to go turn my simple
    things now! 🙂 I REALLY was helped by your big tool example and
    explanation! Thanks, thanks, Thanks!!!

    Very helpfully, thanks.

    Hi Tom my friend and machining mentor has yelled at me because you can
    temper HSS easily …..remember he is an engineer LOL……. The temp at
    the tip where you are grinding is much much more hotter then people think
    and according to him it will soften if you over heat it…..carry on sir

    hi tom,
    i like your way of grinding bits with measuring angles, with references to
    trigonometry. also, noted your steady holding of the bits.
    now, a question: how would you value measuring those angles with a 4″
    slotted starrett ruler with a protractor head. imho, this set would offer
    more flat planes to rest the bit, thus better measurement.
    better, worse, indifferent?
    thank you for the systematic approach and the clear video.

    Another good video Tom. Thanks for posting them Jack

  22. Bad Dog says:

    I have a 12×36 grizzly, the guy that had it before used inserts a lot but
    he knew a lot. I’m just thinking I could spend all freaking week trying to
    make a cutting bit just right lol. Guess we’ll see. I have an old home made
    lathe that came with a crap load of tooling still haven’t gone thru it yet.
    I think the 2 large 8′ long channel irons are going to end up as a home
    made break.

  23. Toms Techniques says:

    Thanks for taking the time to comment, I appreciate it. Tom

  24. Toms Techniques says:

    Thanks, I’m glad you enjoyed it. I thought about making one for the facing
    tool, but there was so little difference , I decided not to. Really the
    only difference is that there is no side cutting edge angle on the facing
    tool. The 30º cut to clear the center is optional. Tom

  25. Toms Techniques says:

    You can use a carbide insert for threading, but it’s much more expensive,
    less versatile and more difficult to use for the hobby machinist on the
    light machinery they use. If I were running a production part on a
    commercial lathe, I would use carbide, but for one off parts like 99% of
    hobby machinists make, HSS is a much better alternative. Tom
