For those of you that use some carbide insert turning tools. have you noticed quality differences? There seems to be a wide variety of prices, so does the quality correspond? If you have any insight as to the differences and labeling, please let me know.
Thank You,
Mike

I have bought those from Eddie, too…he is an awesome guy and a no BS vendor….I like him, but I have some 18mm round cutters I bought from a fellow that is now out of business, they were almost three times the price of Eddie’s and I have to tell you, I felt they cut better. That is why I started the thread…is there a difference or is carbide all the same, or just are some others taking more profit?

I was asking about this vendor in a thread on carbide cutters over at IAP, without much luck.

Not sure if they have what you need, but take a look see when have some time.

The carbides that came on my EWT’s don’t hold an edge for squat. I bought generic replacements off ebay and they are much better.

Most of the carbide is rated with a C designation and number. For a long time all my carbide router bits were designated C-3 carbide. Now, Ill see some with a C-4 rating.
When I was making the live centers I invented, I was looking at tooling, and saw some of the tooling rated at C-7. I think the higher the number, the harder or better the quality.
Ask whomever you are buying from what the rating on the carbide is…............... Jerry (in Tucson)

I have been very happy with the carbide inserts I have purchased from Eddie Castelin. That being said, I don’t use my carbide tools much … only for roughing, then I go to HSS tools for final shaping and finishing cuts.

I took a quick look at carbide grade for wood. Iscar “a very good company” suggests C2 for wood.
There is a balance that must be found of shock resistance and wear resistance. This balance could change on a rotary tool vrs a fixed tool such as for a lathe.
C2 has high shock resistance “resists chipping of the cutting edge. C7 will have better wear resistance, but is not so good for shock, interrupted cuts, or incurred chatter.
Carbide will wear, most often its better to have the edge wear some rather then chip. That is, a smoothly worn C2 edge cuts better then a chipped C7 edge.

Quality of the carbide….
The good carbides are expensive. Those are made with finer particles of carbide and the other alloys.
For example, my favorite is Micro 100 brand. One C2 grade Micro 100 cutter will out last 20 made in China C2 grade cutters.

It would appear that most wood cutters are softer grade carbide, the much harder grades could be a hazard for breaking apart and ending up in your eye.

More or less, its the quality of the carbide more then the grade that makes a better tool.

Unbob,

Carbide tool makers & woodturning vendors command high prices for their carbide cutters whether buy at a store or pay shipping for a single cutter. EWT’s second link says their research found C-3 carbide best for woodturning.

http://www.woodturnerscatalog.com/t/131/Carbide-Insert-Turning-Tools

http://www.easywoodtools.com/ewt-genuine-carbide-cutters-product-page/

Capt. Eddie little more reasonable on shipping. Mike thought I saw 18mm round cutters there.

http://eddiecastelin.com/cutters_only

I remembers Ken from Woodchuck tools, had better prices on tools and cutters just did not know no longer in business.

Woodturner’s new & old embraced carbide tools until time to replace cutters. Re-sharpening became an issue; many turners do not have CBN wheels on their grinders. Diamond card files only work so long if at all.

Know many pen turners went to places like carbide depot & e-bay where could buy 5 or 10 cutters for the same price of a single cutter.

I bought this shear scraper with extra cutters and really disappointed.
http://www.packardwoodworks.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=packard&Category_Code=tools-srby-shear

Blame myself and not the tool or cutters, bottom line do better shear scraping with my conventional HSS gouges and scrapers.

I went to ISCAR Metals USA and looked at their catalog and did not find any C-2 cutters for wood. Could you provide a link with prices?

Thank you all for your responses..especially unbob and Wildwood…this was exactly the info that I needed. You guys are awesome.

I really liked doing business with Ken form woodchuck, he is a first class guy. Last I checked he still had a website up but did not answer the emails or phone calls. I still check in most days on the IAP, I just don’t post any more…too many cranky old %$*^)’s….and at last I heard he had some medical issues and I have never heard the outcome.

So I came accross Eddie Castelin, talked with him an the phone and ordered some stuff….first class act…. for sure….but I just feel that his inserts dulled very fast. Now, keep in mind I am using them to “hog out” the center of the bowl, so maybe that dulls them quickly by nature…I just wonder what C-? they have…..he has a great price…..

I agree with you Wildwood that sharpening them on a diamond hone is not as good as I would have imagined. At least from reading some of the posts…some people say they have great luck….maybe I need to hold my tongue different or “wear yellow socks while sharpening”.

Anyway thanks for all the help, everyone here is very helpful and has always been kind to me….
Mike

Sorry, should have elaborated; I primarily turn dry hardwood burls and all my roughing out is done with the Kilian nanograde carbide cutters. Believe me, I have tried them all over the years and that is why a turning buddy and I started our little business (Kilian Tools) with these top-line cutters.

Has anyone asked Ken where he was buying the 18 mm round inserts or was he making them? Do we know if Ken’s inserts where c 2 or c3? I need to order asap. Does anyone know if the 16mm will work with Kens tool he sold?

Gtorbert,
If you mean Ken from Woodchuck tools, I have had no success contacting him. I have doubts if he is in business. I tryed his phone and his email. I don’t know if his inserts were C2 or 3, but I do recall a post on the IAP several years ago where he talked about his cutters vs others, but I can not find it in a search. What about Capt Eddie, ask him what his cutters are rated. He ships quickly.
Mike
