        Just out of total interest, does anyone use these cheap carbide lathe tools?

          I've had some, in my opinion, good quality HSS is a better bet.

            Don't buy tools in sets. You will not use three quarters of them apart from possibly spanners

              Unless it's cheaper to buy a set!

              Much depends what you're doing of course, some need only a limited range of tools in their workshops, others make good use of everything.

              For a beginner buying a set of HSS tools is a good way of learning what they're for and which you really need. Or not! I bought sets to get started and don't regret it. Now I know more, I often target replacements as Roy suggests.

              Although I'm a metric workshop, I've found a set of common Imperial Drills to be invaluable even though I don't use them much. It's because I'm particularly annoyed by coming to a stop because I don't happen to have the right tool handy.

                I never got on with the brazed carbide tools. Honestly I think they are rubbish. I get much better results with both HSS and indexable carbide.

                  I bought a set like that years ago, they were rubbish, I threw away some and gave away the rest.

                  This type of set costs more but at least has the codes on the sides so you can buy more inserts.   

                  There are a lot of tools with inserts which look alright to the novice, but make the more experienced of us want to puke.

                  Ebay UK 263527683427 (I tried twice to cut and paste the listing without success)

                    I'd go for something like these in the same price bracket. The quality isn't half bad. For the price they are hard to beat.

                      $32 for 20 tool bits. $1.60 each. Including shipping. Yeah they should be good.

                        If an ebay listing similar to Hollowpoints' is available in OZ, it would be a good choice.

                          Just received the following **LINK**

                          11 days for delivery and, at the price, appears to be extraordinarily good value. Had a quick look and it all looks good – the bearings spin sweetly, the chuck is a little jewel and the drive pulley looks to be standard. Don't know whether the "only one left" is 'click-bait' but seems a reasonable bet, price-wise.

                            To my surprise I learned on this forum that brazed carbide tools are often sold unsharpened! Nothing wrong with them apart from the need to touch them up with a suitable grinding wheel which most of us don't have. Not working out of the box explains my bad experience with them.

                            Although brazed carbide tools have their uses, they have none of the advantages of indexed tips and are harder to sharpen than HSS. Beginners avoid!

                              You can run them as fast as insert tips

                              You can cut hard or chilled metals with them same as carbide tips

                              They are more durable than carbide tips as the edge is not delicate.

                                Proper carbide inserts have sophisticated tip geometry which hss and brazed carbide cannot match. Only first generation inserts such as TPUN lack the advantages of modern types.

                                  For a handy source of tips for the like of small boring bars get hold of a worn out carbide tipped circular saw(one of those round things with teeth for cutting brown stuff), remove the remaining carbide teeth, these can then be brazed into a home made tool holder. Watch out the tips are ground alternately left and right. Sorry it does not show up too well.

                                    Interesting that no one uses them (neither do I) because there are so many ads for them on every machinery/tool suppliers pages/website.

                                      Well I use em, I don't have any issues. Have a set of 16mm that I use on the big lathes I have access too (Edgewick, Holbrook and Harrison), some 8mm ones I use on the hobbymat at home and occasionally on the myford. Out of the 16mm set I don't think there is any I haven't used although perhaps not for their intended purpose! Ie the parting tool has been ground into a long reach threading tool and a couple of the others 'butchered' to strange shapes to suit difficult access areas on some iron castings. That said I also use HSS and indexable tips on all the machines. I have a 1" square long boring bar (home made) that uses round HSS bits. Tend to use whatever will work the best for whatever job is being done or whatever is the most cost effective way of getting decent cuts. Can't really understand why people get hung up on one particular tooling type, they all have advantages and disadvantages, why limit yourself? I also save the blunt or chipped indexable tips and if I need something obscure braze em on to a bit of bar and free hand grind them, handy for custom bars for the boring heads. Sometimes I will rough out with a tipped tool and then finish with HSS. Only indexable tips I have never used I think are screw cutting tips, mostly I grind them from HSS although I do have and have used some brazed tip ones. I don't need to cut any micron perfect threads so my methods suit what I need to do.

                                        I use them too, particularly the cranked ones with the radius end, ideal when you want a radius fillet in the corner of something. I used to use them a lot more at one time, most of the turning on that Minnie in my avitar was done with a R/H, L/H, two cranked radius and a parting one. Though probably not as cheap as the ones shown I used to buy individuals from M.E.S.A.S who are no more.

                                          Back in the day, 70's, there was little choice other than brazed carbide for heavy machining. Part of being an apprentice was learning how to shape them including the top face. I still have the skill, bit like riding the proverbial bike, and use them but the hobby ones are so much smaller than we used on big lathes and borers so they are fiddly to grind. There's a place for them, tips and HSS it just knowing where and when!

                                            Afraid that my experiences with brazed tip tools have not been good, especially ones for screwcutting.

                                            Either HSS, or replaceable carbide tips, for me!

                                              I use both depending on what I've doing, especially useful for cutting through the skin of cast iron.

                                                I have a set of pretty little colour coded ones i bought for my taig lathe and once you strip the paint off and sharpen them they work ok , I don’t use any special wheel for carbide just the standard aluminium oxide wheel that came with my bench grinder. I chucked them in some acetone to strip the paint off the shank as it saved making a mess with the wire wheel on my grinder .
