The Novapick teeth won't hold up at all in concrete. It's a good idea if you have a machine totally dedicated to nothing but wide open asphalt milling. But taking asphalt off concrete and obstacles like manholes, water meters, and buried rail lines are the death of this system.
We are loving the novapick setup...252K+ sq yds and changed 4 teeth in that time.
With the price of teeth skyrocketing over the $5 mark,the owner is looking at adding novapick to the other mills we have.
Yes milling drum it is a lease to buy originally the rumor was a rental,they have not put the scale on the conveyor yet,first month is complimentary I assume.
According to the person in the know at the company I am with.. the allotment of teeth is 80 per 100k ton.
Buried rail lines are the death of any drum tex....I dont understand why trimming around obstacles would be a problem for any setup and I have already trimmed off some bridge decks and the end result was a happy contractor.

I wonder what will happen when the drum itself gets tired and needs a retool....it isn't like they will last forever. I wonder how much that will cost when it comes to it...
Nobody seems to say much about them at that point...hmm???
I think we set some sort of record today with an unbelievable amount of teeth changed.
25 pails or about 1300 teeth in 1 km 12.5 ft wide 5 inches deep.
teeth changes every 100-150 meters including 9 holders
w6
w7
road razors
and some others all failed
I don't think we have ever changed more then 500-600 in a day ever!
Hay bean where are you working so I never go there (northern ontario) we were changing about 500 a day on the 401 in Gananoque on our half lane machine.Originally Posted by bean

Way up north of edmonton (6 hours) in alberta, kennametal rp-20's seem to be the best we can go 400 meters or so on them compared to 120 with the others.
We did the parkway in gananoque a few times and had to change teeth twice a day it was some hard **** aswell.
Last week at a company in Utah (CMR = Construction Material Recycling) I saw that Sandvik are putting out a tooth simular too the Kennametal 20's, it looked exactly the same except the color was a little different and they came out of a Sandvik box...
I'd be hip too trying those bad boys on for a go too see how they hold up.
CMR has become a serious thorn in my side bidding wise lately. You working for them now?
That new Sandvik tooth doesn't seat fully on the washer. I think they did this to get a puller under the tooth. Good idea. Too much shank sticking out above the holder means the shank breaks in hard material. Bad idea.
That's something I'd be interested too see Tex, I wonder if that is unique to certain holders or not....
CMR came after me pretty hard because I am friends with some people that work for them, when push came to shove they couldn't take me on....I'm done with Kodiak, running a mill that requires turning the steering wheel 30 times to get the tracks to move 2 inches....is simply unreasonable.
the best teeth by far over all the others i have used have been the cats with the green lids..Im talkin days untill ya gotta chang them..used them in tucson overlay, up on the 260 north of payson and on I-10 fast lane which was hard cuttin 5" I ALWAYS put extra water down, just cuz I would rather watch the water truck driver hurry his ass up then me havin to change my teeth all the time.
Novatek will soon have a tool for the Wirtgen that will replace the HT11 holder and the tooth. ( Diamond tooth of course)
Wow, that will make alot of people happy.
But I'm a little confused, are you meaning the entire holder and tooth? you mean a complete new holder that slides into the existing HT11 hole on a wirtgen drum?
Anyone else use Kenametal bits? Seems they wear quickly but not that exp.
The rate of wear really depends on several factors. The aggregate being cut is first. All the tooth companies make several different styles and sizes of teeth. They don't do that just because they want to. They have discovered over the years that different teeth work in different conditions. Also the size and horsepower of your machine will help determine the right tooth to use. Secondly, if the teeth aren't getting enough water, they will wear prematurely. Check your spray bar to make sure it is working properly. After that, I would check the condition of the holders and the lower conveyor. Worn out holders will kill rotation and if the lower belt is too worn out, it won't pick up the material and allow it to stay in the box longer than it should. That helps wear out everything. All of this is, of course, just my opinion, but I hope it helps. You probably already know everything I just said, but here it is in case you didn't.
