In a review of Forum guidelines and for the fact it has slowed down considerably around here, its worth pointing out a process that has been used on crusher blow bars, hammers and Vib plates has been successfully used on mill teeth.

If you are interested in reducing the amount of teeth your operation use seasonally, please let me know and we will be able to see what is available for demo. A large milling contractor in the mid west has noted they have reduced the amount of teeth they use yearly by over 40%. That means they are keeping more money inhouse and not committing to old formula amounts of what they used to on bids, it means they come out ahead in a few different depts.

Yes, it will change how things are done and you saw it here first.

Mr Bean, My favorite border poster...

Its a process of cryogenic fusion, it does work and it does allow you to run alot longer on a set of teeth then what your accustomed too. If i can make some attachments I'll send you some reading material.

I'd like to hear more about this also. Have these teeth been tested in concrete as well as asphalt? When you can, please send me some information also. Thanks!

I would also like to know what its about and how it works. Whatever you could send me would be appreciated.

For those of you that use Kennametal or Sandvik how many choose their valve seated carbide tip options i.e. for Sandvik the numbers would be NP01, NP27, NP86 or NP96. If you do can you share with us why you make that choice?

I am not sure if Wirtgen or CAT offer a valve seated carbide tip option so if anyone can chime in on those it would be appreciated.

On a completely opposite note, what do the words strength, toughness or durability mean to the contractor when it comes to how well a carbide tipped milling tooth performs on the drum??

We are having good luck with diamond teeth the cost is much higher than carbide. in fact you pay by the ton produced (rent the teeth) This is hard to get used to at first. you have to set up with there holder etc. In other words you need to change drums. its a commitment for sure. We can run days on end and never change a tooth sometimes weeks. the down side is, if you stike a manhole its going to cost you about a hundred bucks a tooth. In the right application they rock.
as far as cryogenic treatment I cant comment but I am very interested to learn more. the company is Cryogenic Engineering out of Cedar Rapids Iowa a google search should get you to the right place.

CMIfan is absolutely correct...in the right applications diamond teeth rock.

We actually don't have a website at this time. If anybody would like more information you can call me at 319.560.4092. Our findings support that if you are wearing out carbide tipped milling teeth and subsequently replacing those teeth because of the wearing away of the carbide tips then the cryogenic treatment will help. I will admit the technology isn't for every contractor but for those who experience significant wear on their carbides it does provide significant benefit.

As you all know the name of the game is to exchange expense for profit so if you enjoy changing teeth then InvisaTuff is not going to be of interest.

Just curious when the diamond teeth will switch from being leased to being offered for purchase. It would be a great opportunity for a study to be done to analyze and measure the potential life extending properties of cryo on diamond teeth. With the carbide collar I would say there is better than a 50/50 chance of making them last longer.

That brings up a question. What is the biggest reason for changing out a diamond tooth? What causes them to fail?

Diamonds are great in asphalt, but they do not hold up to any kind of impact. Concrete destroys them in no time. Also, milling around manholes, water meters, or anything else in asphalt runs the risk of destroying the diamonds. They are only cost efficient if used when there is no chance of hitting anything except asphalt. If you have in-town work, they are useless.
