Tormach Explains Tool Coatings

Choosing a cutting tool can be a daunting task, even more so when you realize the variations in coatings for different types of materials and cutting strategies.
This is a guide to what coatings can do and incorporating them into your machining.

Very informative and useful information. I think is the most understandable and nice video of coatings, properties, colors and applications ever. I really enjoyed it regardless some questions that I have. Really nice job. Please keep shearing information. Thanks a lot.

[@FlorinC1984]

Awesome. Educational and very interesting (thanks to the presenters). Thank you, Lady and Manly Man!

[@jaypierson5955]

Chris is a natural! Great info.

[@douglasdarby8584]

I personally thought the presentation was fine. It's a detail filled subject and as a beginner it's a little "daunting" but I will do some additional research to see if I can simplify it for my mainly Aluminum needs. It is easy though to stop the video and take a few notes and then resume to the next coating... Thanks for taking the time to put this information out there.

[@fisterB]

Good presentation. I am not using such tools but I enjoy the ingenuity and the gorgeous colours of these coatings.

[@Charliechoes]

Hat off for the lesson.

[@mitweakz866]

I enjoyed the video and learned, thanks , greetings from Mexico

[@EZ_shop]

Good job guys.

[@xXDEFIENCE2066Xx]

Lmfao love this video I wanted to know what type of coating to get on the drill bits for my 80% receivers and what type of coating to get on my glock slides and this video is a life saver 👍👍👍👍 you guys are awesome 🙏🙏

[@orangsederhana3073]

thank you for sharing in this channel, wow .. i have drill twist that Tin coated.

[@mikemudimba5531]

I love these guys kikikikiki thanks for the info

[@Dinadinaf]

Thank you so much.

[@gurudath6967]

thank you

[@henrickcasanova5314]

This was cool.

[@shubhampatne703]

Thank you Sir and mam

[@kalabrushka]

keep it up

[@labhsinghramgarhia5892]

thnx man

[@krishsahu4935]

Plz make a video on coating process

[@MagnetOnlyMotors]

Wonder if the coatings ever need coatings ? Just being silly. Great info,thanks

[@tivnator]

Why the TiCN has a black color and not a bright brown like copper that we use to see everywhere?. I have seen that the TiCN has the color of your TiALCN so how that's possible? I'm confused. And also some people say it is suitable for inox. Could you please explain it?

[@MrVajutza]

+Tormach Inc, Good information about cutting tools, but be extra careful when quoting the Periodic Table. Fe O is not Oxide, its Ferrous Oxide. Oxidisation is usually when Oxygen interacts with an element by stripping off electrons (very short description of the process and doesn't tell the whole process). A good reference to find more on this would be Materials Science and Engineering An Introduction,9th Edition.

[@tormachinc]

You are correct that it is Ferrous Oxide. The tooling industry shortens this to just Oxide or Black Oxide.

[@drealraj]

what type should i buy to try notching tubes / pipes ?

[@tormachinc]

Thanks for the question! Reach out to the Tormach Customer Support team at [e-mail] to get specific information on tooling selection.

[@richardlee866]

Carbide with the right coating whatever the application calls for is much more cost-effective than high speed Steel.Carbide without coating is still a better choice than high speed most of the time if someone is just starting out and can't afford carbide be cost-conscious then move on to carbide coated when you can afford to they will pay for themselves over and over again they hold their dimensions longevity for more precise tooling applications.

[@alphacncco]

dear how to verified engraving tools hrc45, hrc55, hrc65 carbide

[@entrelive]

Carbide end mill 2mm 4 flate can cut steel

[@GabrielRodriguez-dk5xc]

Good

[@tivnator]

In the image there's a blue coating which is not explained in the video. I have seen also a metal blue and metal purple coating do you know something about it? Please explain

[@tormachinc]

The colors come from a combination of the processing and the materials used. The darker blue and purple end mills have a higher concentration of micro-coating, which increases their hardness, but also increases their resistance against materials.

[@bb21again.67]

Can these coatings be used on engine components?

[@AqibKhan-xf8vo]

I want you tell about drawbacks of these coating during machining process

[@lorgaraurelian4076]

Voids would be the major the ones. CVD is high temperature so warping can occur. PVD can arc a part to hell.

[@drevil2783]

All the different coating processes and or elemental compositions mean nothing unless you know what you are gonna cut. What speeds are needed and the relevant pressures needed on said material. Once you know the above then only can you select the best tool.

[@ajfitness6762]

sir my question is all cutting tools they actually need the cotting cumpulsary cotting tools or non cutting tool which tool are give a good finishing thats all

[@muzammilhussain4441]

I m lath operator & well

[@arthurn9237]

THANX FOR AN INFORMATIVE VIDY JUST WHEN YOU THINK YOU KNO IT ALL 🙄 OR MOST OF IT YOU GUY'S COME ALONG AND ADD TO MY KNOWLEDGE THANX AGAIN

[@namupalanen5647]

Next in line same cutting conditions on same tool on same working conditions on different materials carbon steel, tool steel, stainless steel, stainless duplex grade, hardened steel and few aluminium from soft to better grades on and off coolant and let's compare how the different coatings work and what gives the best tool life on what material. Now that would be a video ;) Never gonna happen :D

[@tormachinc]

This is a good idea. We'll put it on the list!

[@Th3mast3r69]

What about ZrN?

[@johnrohrer1300]

Just an FYI the coaters for PVD do not get to 18000 degrees F they get up to around 900 F comon man

[@N.g.Chanal]

how many cutting speed of 12mm solid carbide end mill on soft steel?

[@sarahnikas1344]

18,000F? I think you meant 1,800, no?

[@lordtigranes9877]

What about cobalt?

[@loganschott9712]

cobalt is an alloying element in steel, not a coating

[@lorgaraurelian4076]

Cut to the chase. TiC. Titanium Carbide. Very hard. Heat resistant. Not prone to thermal shock. High lubricity. CVD coatings are the thickest and toughest coatings. Albeit, they are done at higher temperatures compared to PVD coatings. Material warp may occur because of the high temperatures (ball park 1875 F or 982 C). This will require that the parts get annealed and heat treated post coating. Some steels that won't work with CVD processes are A2 (too much sulfur), D3, O2, and all low temp materials. Of course the version of CVD I am referring to is known as Thermal CVD. There are many other versions of CVD available such as Metal-Organic CVD, UHV CVD, etc. To surmise, PVD coatings are good, and reliable. Turn around time is faster than that of CVD. Tends to be more inexpensive as well.

[@michaelmcallister3429]

18,000 degrees or did you mean 1800 degrees?

[@PowerSports]

My understanding is that AlTiN is different from TiAlN, no?

[@tormachinc]

They are different, but similar. Both AlTiN and TiAlN use an alloy coating of Titanium, Nitride and Aluminum, but AlTiN has a higher percentage of Aluminum over 50% atomic . This allows for higher corrosion prevention, increased hardness, increased tool life and higher temperature range.

[@chesshooligan1282]

@@tormachinc I read elsewhere AlTiN has inferior hardness to TiAlN but superior heat and corrosion resistance.

[@rene5853]

Didn't hear tungsten carbide why not mention it?

[@tormachinc]

We missed it. Sorry about that.

[@MrTjmk]

What???

[@ANTALIFE]

The woman looks and talks like Simone Giertz

[@dinosoarskill17]

[@mattapple2105]

Yeaahhhh...that is a little to much information if you got just started at Machining : (

[@andriusmotuzas9224]

cringe, but good info
