Buy Kennametal Inserts?

Where do people buy carbide inserts for kennametal tools? Ebay?
Anyone make aftermarket versions cheaper?
Thanks
 
eBay / Aliexpress etc.

You can get original inserts cheap but have to look for them on eBay.

You can get better inserts as well - based on carbide grade / what work you do.

You can get cheap / very cheap / uber cheap inserts of aliexpress - again all depends on how much you want to spend and what you are doing & how often you want to change inserts / what speed you want things to run at.

You can buy a box of these on aliexpress for similar price to a single one on this site. Same brand. Same box. Same insert.

Accusize is not a brand name - it is the very cheapest Chinese inserts.

Same for a lot of other inserts. It feels their markup on inserts is close to 1000%.

Popular on aliexpress are Mitsubishi inserts. A lot of inserts are made in Korea and Japan. I am guessing less then half are from China.
 
Since the OP asked about inserts for Kennametal tooling, I figured they would want name brand, hence CTS.

BTW, None of that part number to be fond on Aliexpress. And CTS, while an Accusize distributor, sources most of their parts from e.g. overstock at suppliers etc. While looking at Mitsubishi on Aliexpress there are very similar pricing, as in >$50 for 10.

Yes, I do buy no-name inserts on Aliexpress, I expect little life from them, and that is what I get. Those generally provide zero clue as to what they are for, just dirt cheap. Given the cheap price at present I don't care but that is slowly changing as I get into more demanding work. Thus I will have both types, known brand/type/quality, and throw away ones for mystery metal use.

Maybe I will get motivated and buy some known source vs. same brand from Aliexpress and put them under my optical comparator at 100x. I know Stefan has done that, the differences don't show up till you magnify them.

What do you mean, I get my Mitsubishi for like $10 for 10 pieces off aliexpress.

Mitsubishi

I wonder whatever they do not advertise the brand with inserts as they may send same grade of different brand.

Also it is possible they are a factory for say a big brand name or a distributor but they cannot due to legal nature actually disclose what it is - this is why when you look at a lot of inserts they rarely show the logo or name of manufacturer.

I also wonder whatever some of these are knock offs in China - I seen more and more coming in with 3d holograms of "authenticity". Thus I do suspect there may be some cheating going on.
 
The ad doesn't say Mitsubishi so why would I assume that they are? I also can't find the previous Korloy that you mentioned. Just like many other inserts don't say what material they are for. Crap shoot, great price, throw away items, might not be what you need after all.

If I need to be sure what I am buying, I will use CTS as there is some traceability there. For the other 95% of my needs I will take the chance, as do you. I think I see part of the price diff, you seem to be in US$, I look at CA$ since that is what I am paying in. So your latest example is not $10, but $16.89. Still cheap, but not visibly branded.
 
When cutting 4140 I did some tests and the results were not promising for the inserts I was able to buy offshore. I get very long life for my $14.00 locally sourced Kinnemetal inserts. The life for any offshore insert I've tried has been very short - one long cut or less.

I just don't have the deep pockets to randomly buy until I get longer lasting inserts. I'm done with offshore for tool steel after > 10 attempts. I will continue to use offshore for aluminum and brass ONLY.

Thanks for all the replies!

My problem with offshore ie. aliexpress / accusize is that I cannot find an insert number that compares to the kennametal insert number.
How do I know I am getting the correct shape/size?

I need EDPT or EDCT inserts.
Is there some way to convert the code that I am missing?
Thanks
 
@chupac What you are finding is the difference between the ISO insert designation and the SAE sizing. For your kinnemetal holder, you can get your dealer to tell you both designations. [that is IF your kinnemetal holder is an ISO holder, which many now are - only about 1/2 of my kinnemetal holders are ISO standard]

I'm no expert, and there's other guys on this forum that do this stuff every day.

Here's what I'd do:

1. look up my exact K insert on the web and then check Carbide Depot to see what they have that is compatible. As a thank-you, you might even order from them a time or 2. The key thing is that an expert like that will be able to help you.

2. I'd call a Mitsubishi or Sandvik rep and ask them what they have that will fit your holder. IF they have a compatible insert, you can be sure it is an ISO compatible holder.

3. There are charts on the web that convert all the insert designations between the 2 systems of nomenclature. I used one 2 years ago to find a compatible insert for my TPNG 322 inserts. (sorry I don't remember where that one is).

I'd be interested to see what you see.
I must have missed that Stefan episode. Do you recall about when it was or link?
 
Kennametal doesn't sell inserts online, same goes for allot of good brand name tooling. Call or go to Source Atlantic they are an authorized distributor. You will be able to find other retailers here in calgary.
 
@Alexander I was hoping you'd comment...

--Do you mean Souceatlantic.ca? They seem to have Sandvik, but not Kinnemetal, K isn't in their 'brands' list and comes up blank in search.
 
I'm sorry Tom but the total cost to me for those is $47 so no, not a bargain once they arrive. I agree that the base price is decent. Close to nothing from US is worth buying in the end at their generally extortionist shipping fees. I know, I'm hard to please, it is the frugal in me I think.

The chart is very handy, thank you.
 
Well if you wanted these my cost is like 20 CAD maybe 25 CAD all in. I actually think I have lots of inserts in that size. I wanted to buy some this time but decided to shop next week.

You have a different source than ebay I assume? The kennametal ones I want are ~ USD $15+ each on ebay plus shipping. Actually cheaper for me to buy them locally. No shipping.
 
I personally try to stay away from ebay and amazon for certain name brand items like inserts, especially Sandvik and Kennemetal.

Just like Mitutoyo digital calipers, there are too many fakes out there, and my money is better spent on authentic inserts through authorized channels.
 
It is a trusted seller. Stuff is 100% legitimate. I simply add on inserts to other items I buy - so with shipping the total cost is just what inserts sold for plus a tiny fee for extra shipping and processing. Items are surplus.

Which exact inserts are you looking at - the code?
