Useful info John. When I worked in the industry I used coolant on carbide tips. I know people have told me not to but I found that my work was getting hot so that's the reason I did it but the secret is not to spray coolant on a hot piece of work because it might break the carbide. I always got away with it.

Hi Dermot, thanks for the comment. Interesting topic that I didn't cover in the video, therefore I will pin your comment. Carbide is OK getting hot (within reason), what it doesn't like is rapid changes of temperature, so either fully flood it with coolant throughout the entire machining operation, or don't use any at all. Don't apply it mid cut when the insert will be hot as it will fracture. Cheers, Jon

Good job tackling the big question. When people ask me for advice in their home shop I give pretty much the same advice. 1. Tool steel and the skill of grinding good profiles is a must in a manual machine shop. There are many times you'll need a one of cutter or can't get the right cutter in time. 2. Qualify your equipment. How capable are your machines? 3. What materials will you be cutting? 4. If you are going to use indexable carbide, try to minimise the amount of different profiles. Look for boring bars, facing holders, face mills etc. that take the same insert. 5. Don't waste cutting edges. CNMG's are a perfect example as you can buy off the shelf holders to use up the 'uncommon' corners. These holders can even be used in a shop made fly cutter. 6. Buy nice. Quality tools wear the badge 'quality tools' for a reason. Even if it takes you a little longer to get the cash together for them, the rewards are worth it.

Thanks Jon. Great Information. Shame that you did not touch on Braised Shank Carbide tools for turning. Cheap to run, just touch them up on a GREEN wheel. The other benefit is that you get a razor edge and can take 2 thou cuts, you don't have to do balanced cuts due to standard inserts being blunt. Enjoyed the chart explanations.

Don't mix balanced cuts with sintered inserts issues though, balanced cuts is a variable control method for hitting sizes regardless of cutting tool material. Agreed that ground sharp carbide is a totally different and can do shallow cuts very easily. Carbide is such a huge topic, I plan to do a similar HSS video at some point in the future to give a more balanced view. Cheers, Jon

Good video Jon. Interesting big question. I think people use carbide because they are lazy and can't be bothered grinding and resharpening HSS tips. Sounds harsh, but that's my take on it. It's much easier to just reach for another insert ;) These days HSS tends to be seen as "old technology" in much the same way as gas welding, which is a disservice to both mediums. Interestingly when you buy a new lathe for home use when they throw in a cheap set of tooling it's invariably brazed on carbide. So I think people are conditioned to using it from day one. I hadn't actually thought about this topic until now as I'm so used to using both. One thing carbide definitely won't tolerate is stalling or stopping the machine with the insert engaged - goes bang for sure :) HSS can take that and a big range of other punishments. Cheers Rob

Hi Rob, thanks for the comment, couldn't agree more with all your points. It's a very interesting point, I agree on the laziness aspect, which could also be driven by the fact that HSS grinding is just not taught anymore so new entrants only know carbide as an option. Cheers, Jon

Sorry Gents. Completely disagree re laziness. It is lack of experience in the grinding of hss tools that is the issue here. No one who is lazy goes to all the trouble of sourcing machines and setting up a home shop. Cheap carbide inserts from China have been a game changer for home shop types who just want to turn up some parts for a project and experience the joy of making something. Gas welding a good analogy but not how you suppose. No one wants potentially dangerous acetylene in a home shop which may be in a residential setting. On the other hand we can now tig weld and braze affordably. Changes in technology and economies of scale have brought these techniques into the realm of the home gamer. So it is with carbide.

Fantastic video Jon! Another trap for home hobby shop is the quality of the insert holder , I have used some good ones ( Seco and Sandvik ) and had some that were utter crap - they were sent back to where they came from via the scrap metal bin , probably a part of a Chinese car now ! I think it is a good idea to have at least one carbide tool for the lathe and mill regardless of whether it is an insert type or brazed type for machining iron castings or that piece of unknown steel that we all seem to have hiding in the pile of offcuts in the workshop !

@chrisbaker38442 жыл бұрын
For most people the ease of use that carbide gives is the biggest factor, take it from the box add it to the tool and it is ready for use. HSS has to be ground to the correct profile, honed and if you are skilled at both of those you have a tool that will cut, if not its back to the grinder and start again. I am not saying that carbide is the best just that for most home shops it is probably the easiest, right or wrong is up to you to choose.

Just to add a bit of explanation, Jon was my boss, needs saying. In aerospace with certain components you have to do surface finish cut ups. Loads of parameters are looked at by the lab. Redeposited material etc. this sets the life of carbide for that component. So if your supplier says an insert will be ok for 300 components and we do the first cut and 300 part cut and it passes. That’s your tool life set for that insert. If the supplier wants to do say 600 components, that’s a big cost to do the cut ups. Firstly you need to make an extra.300 components that have to be quarantined and then the cost of the cut up. If it’s fails you have 300 components scrap. A little explanation why aerospace throws away good carbide.

Ok here is my slightly different take on this subject. There is only one thing you need to know about carbide in the home shop. It cuts metal. The "cheap and cheery" (registered John Mills trademark) bang good inserts are wallet friendly enough that you can buy a few different geometries and experiment to see what works on your particular machines. We are home gamers; some lucky to have pro experience, some not, we learn from people like Jon. At the end of the day, you do what works.

00:04:16 I must complain in the strongest terms that I was expecting cats doing silly things and people falling over. Another super video thanks Jon. Very good balance of detail. I use round inserts a lot. My lathe is just about powerful enough to take a cut in 4140 that's deep enough to leave a good finish with a CCMT, but it is really at the limits with only 3HP. I don't use cheap inserts. Almost all of mine are polished CCGT09T3xx, DCGT11T3xx or VCGT1604xx for aluminium and coated versions for stainless. I rarely use HSS except for form tools these days, and I've started using a 3mm diameter Korloy KRGN300-A insert for internal and external grooving for O rings and stress relief fillets. I grind custom carbide boring bars for really small work using a diamond wheel on my ancient Alexander (Deckel clone), and I turn and mill custom D bits from tool steel, then harden and grind them. Following Stefan G's example, I've even been regrinding some carbide inserts for special applications on stainless and titanium. Horses for courses, as you said. More cats needed. This is the Internet, after all!

Hi Trevor, thanks for the comment and support of the channel. You are actually OK going past centre, I have never had lift off doing this, however, a very common mistake is pushing too hard near the centre pip (especially with big facing cuts). The surface speed is near zero and this has a very damaging pressure effect on the inserts causing them to fracture, if you then go past centre, they will lift because they are already weakened. Hope this makes sense. Cheers, Jon

Interesting. My mill has a lot more power than my lathe, but I mostly use HSS in the Mill, (except for face mills) but I use carbide in the lathe, which does struggle with the carbide on steel, cant break a chip with it to save myself and quite shallow cuts. But what it comes down to is that I dont have the gear or skill to grind HSS tooling for the lathe, so cheap chinese carbide meant I was right to go out of the box when I bought the lathe, so I have just stuck with it. For the Mill I treat the HSS tooling as disposable, because chinese HSS end mills are cheap as chips and take a flogging.
@chrisstephens66732 жыл бұрын
What ho Grasshopper, All good info but, there had to be a but of course, the chip breaker has an enormous effect on TC insert usage and this is where at lot of the anti probably came from pre PRC made tooling. The chip breaker defines the range of depth of cut an insert is capable of, some will not cut less than a several mm, while others can cleanly cut 10s of microns. In the early home use of inserts, people thought it works for industry so it must be the best and i must have it too but surplus tips where indeed for very heavy machinery and nearly useless on a Myford. Unfortunately there is no universal standard for chip breakers and there is no catalogue for unnamed brands so you are reliant on the sellers description which may or may not be helpful, but inserts for aluminium may well be the best for all round use in a small shop if no better info is available. Just my take but you get what you pay for and my comments are free.😉 ATB c

Since nowadays the home shop is probably predominately chineseium carbide how about an explanation of their classification and how it corresponds to ANSI and ISO and how it does not (or if they have one at all which I suspect). Surprisingly it seems that just recently some of their manufacturers have put out an index on grades of their proprietary products as to what they can cut in material. Useful but does not seem universal in any way. I for one know that I could not afford to run carbide or carbide toolholders if I had to pay the staggering cost of the name brands. And yes I know they are much better in quality control and predictability etc. However I cannot afford to pay over a hundred dollars (quite a bit more) for their toolholders and then pay more than twenty dollars per insert at a starting price. So it is useless for the commercial guys to keep harping on how you ought to stick to name brands and their prices which they pass along to their customers but has to be absorbed for the home machinist. It would be helpful in light of this to have a map to navigate the chinglish market place where little actual understandable information is listed with the ads selling the carbide and accessories. While I have been using it for more than ten years now I still feel lost when trying to reorder ( it is rare to have any label with standard nomenclature on insert boxes). I know they have some pretty high quality stuff and some pretty bad but the price is usually receptive to taking a bit of a gamble. I often wonder too if the name brands you see from them are actual back door products of the brands or just outright lying as they love to do. The attraction is there when a box of ten inserts can be as little as $4 US while just one brand name western insert can easily be five times that much! Of course their search engines leave much to be desired and while they have many items finding them can be a real chore.
@jonsworkshop2 жыл бұрын
Hi Douglas, thanks for the comment and question. I wish I could help you. Most of my carbide is partly used good quality stuff from industry that conforms to the ISO standards so I really don't understand the Chinese codes at all. I have tried to get to grips with it but depending which site you go on, it changes so there is no real standard or consistency unfortunately. My only advice is to buy your tool and inserts from the same site, and buy enough inserts to last you out while you are at it as they are always updating stuff so you will not be able to get the same inserts in a years time unfortunately. Cheers, Jon
