Three piece carbide insert boring bar set from Banggood - excellent 

Hi Rob. I bought a lathe tool set from Banggood after watching your previous videos. I'm pleasantly surprised by the quality, it's very good value - thanks for putting me on to them, cheers.

I buy a lot on Ali express, very satisfied. But be honest for hobbyists, the quality is very good. Once you have a business you can always go to the local dealer, because you will settle that in the account. The Chinese are a real blessing for hobbyists.

Tx for the tip, i just ordered the same set as in your vid. Keep up the good content and greetings from the Netherlands

Rob I have several different size round boring bars, and to life simple I got some round steel stock, drilled for each boring bar, milled a flat and drilled and tapped for appropriate grub screws. Now they all fit the same round boring bar holder and all are centered and ready to use. John

just used your link and made a 100 dollar purchase from bang good. thanks for the review and sharing the link.

Thanks Rob, ordered this set today after seeing your review. Always handy having additional boring bars, and at the price, I couldn’t resist. Now the wait........ Thanks for all your videos by the way. Great info and very relevant for me as I’m running the same lathe as you. Cheers

Just a tip: Only have the boring bar sticking out of your tool holder a bit more than your desired depth of cut. Boring bars experience lots of tool push due to the length so only stick out what you need to reduce tool push and increase rigidity. Lastly, If you are removing 20 thou, for example you may divide it up in half or fourths that way your final cut is the same as your first. Good Luck!

Good Morning and greetings from Dearborn. Michigan. Thanks for all you do Rob. I enjoy your approach with value always at the forefront. Growing up with nothing made me always keep an eye out for ways to save a buck.

Mine arrived 16th Jan 2018.. They cost AU$18.They look ok, I will test them in the next week or so.Thanks for the videos..

Note: The fine feed rate for this lathe is 0.06 mm/rev NOT 0.5 as stated - my bad. Rob

Thanks for the tip Rob' had to make up a 16mm boring bar for some hss for a internal threading job I did restoring my machine vice - it took a couple of hours - Ive just ordered the set delivered £15 ! That will save me some hand filing holes square ! All the best Mat

Hi Rob, Thanks for the review always good to see if whats online is any good.More tests please!

If we want a boring bar, we can just go to any pub in Adelaide on a Monday night :)

I have some solid carbide boring bars that take much smaller inserts than that: CC*T03's. Just as an apropos to how small you can go with carbide boring bars. (Beeing made from solid carbide does not actually have anything to do with taking a carbide insert in this case, it is just to get them stiffer since they are really small) The bar is a 4mm diameter: C04G-SCLCR03. It does add 0 to the price though

Excellent review--looks like a great value. They show up as US$12.33 when I follow your link. Might be worth switching from what I've got (a brazed-on set) just to save space in the toolbox.

The holders I received are negative rake holders, and the inserts are positive rake with no chip breaker and for cutting on one side only. Not happy with the cut. Going to modify holder to have top of insert parallel to the bed lathe and see how that works. Of course if my holder would accept rotation no mod would be needed. Thanks for the review, appreciate it. They are a bargain.

I have one of those that I love , It does a great job !

Those small boring bars would be excellent for model making Rob-- nice and rigid without too much spring..

Great review, kinda want to buy a set, but tied me hands down, mainly because most of the accurate holes I want are in the range of my reamers & I rarely use a boring bar, which probably means some job needing one will now turn up!

G'day Rob. Great review.

I have a similar Banggood boring bar set laying around to review. Also a 7,10,12mm set. Mine came with Mitsubishi inserts. I must say doing a review feels a bit redundant now :) ps. carefully check the coating on the insert pocket. The 10mm I have has some bubbles on the surface. Not something you want underneath a insert.

G'day Rob good review I have one and it's been very good, thanks mate see you soon regards John.

Hey Rob, I found this review really boring!! Come on, someone had to say it. Seriously great review mate.

Hi Rob. I use cnmg tips which are similar shape to the ones you have there although a little bigger. To use up the opposite cutting edges I bought a MCMNN1616H12 tool holder. You could probably get a holder small enough to fit your tips and so double your use of the tips. Ideal for facing & chamfers. Nice review btw. regards from the UK

The 7 and 10 mm bars are made by LI FENG JING MI : www.lftool.com/english/index.asp The 12 mm bar is made by WEILONG CNC : www.wl-tools.com/english/about.asp

that's excellent! so one carbide insert can be rotated one time once it gets dull right? how many DIA 23mm x 36mm deep holes in aluminum do you think you can get with both sides of 1 carbide insert? I'm not asking for any precise estimate, just throw me into some ballpark, do you think I can bore 100 holes (DIA 23mm x 36mm deep) with 1 carbide insert? or maybe only 10? I'm waiting for my 1st lathe ever, and I have never worked on lathes. so I am totally blank, and hence I'm asking dumb / trivial questions.

G Day Rob, I use these same bars and I reckon they are great also. Great banggood for your buck I reckon.

hi rob,you should review a quick change tool post holder next. Hear what I'm saying. you must be one of the last guys using a 4 way tool post and shiming.my god the shiming,having flash backs talking about it.geoff

Thanks for the tip Rob. After watching your video, I went to the Bang Good site and ordered a set for myself. $13 US and free shipping. How can they do that so cheap I'm wondering? Couldn't pass it up.

The surface of the outside diameter of the sample should be smoothed first, and the spindle speed is too slow you need more rpm for small boring bars.

Hi Rob, yes I had seen your mods page, great stuff. I remember seeing another mod with allowed for a manual crack handle which mounted to the spindle in the gear box casing which looked great and be real handy for threading. I’m real happy with the lathe, had it many years now. Only mods I’ve done is the extended handles similar to yours. Considered a vertical mill mod but never got around to it. My biggest gripe is with the gear set up. So much mucking around in changing gears in order to do various threads. I do need to get a live centre as I’ve just used the supplied the dead centre to date. Also wouldn’t mind a quick change tool post, purely for convenience. Any recommendations on a suitable live centre and QC tool post Rob?

I just noticed this set is currently selling on Banggood for about $13 US.

Thanks for the tip!

Shipping cost and time are horrid these days.

Rob, I haven't broken any inserts yet, but just in case do you have replacement details?I couldn't find any..Cheers.....

This is a bit misleading as the boring bar is just steel and not made of carbide. Just uses carbide inserts.

Thanks again Rob. Can you put thread cutting inserts in those?

The last week I purchase the same set.

if you loose your screw, your either a screw loose or your screwed. It's a hard life on a lathe.

This is probably a nicely produced video but it's 2 minutes of information painfully stretched into a 24 minute video.
