Spent a week off work. My Boss said it was my fault, he was bipolar shouldn’t have ever been a boss, but was related to the owner. He didn’t last long, I could tell you some stories.

Well,after reading the thread and all the gory details, I'll refrain from turning the tips to squeeze the last bit out of them.It seems to raise the risk of holeing it through,which then becomes a pain in the leg getting the buggers off.

Used hard facing Wire when wrench at the Utility on the auger flighting and flat earth bits, on the Carbide bit headed augers used it on the climbing side of the flighting to extend wear time where also used it in smaller machine cutting edges and chain style trencher teeth root bases.

We still turned tips after my little faux pas. Just do it before you get a hole in it. The other issue was operators that didn't pay attention and would lose a tip and still keep ripping.

Well,there's 45 hours on that Cat tip,and it's got to go another 60 to break even with the MST Easco tip.
Can't see it happening!
Unfortunately,the D8 is going on blade duties for next 2 weeks,so won't have the final results just yet.

Do NOT believe a flip will do you much value there. Run it til she gets weak then swap to a replacement.

In truth,we never bother flipping them DMiller.
I've just flipped this one for the benefit of the trail.In the 61 hours we got,8 hours were after the flip.

Ditto, I've never flipped a ripper tooth in 53+ years. Purchase aftermarket like BlackCat and have A.R.M. applied either using Mig matrix-TC granular GMA carbide embedding process or Plasma Arc. Plasma Arc is better for higher impact conditions because the TC granules are fused directly into the parent parts' base metal, versus an overlaying weld's puddle.

Right chaps.
The verdict is in.
The two tips uses were Cat long centerline tip and MST Easco long centerline tip recommended by their respective manufactures for my particular application.
I'll enclose pic.

If I figured that right, the ESCO tooth costs 44 percent less to use than the Cat. I think they have improved since my days in the coal mine.

You figured right John.
The Cat tip cost over £1 per hour more than the Easco.
I'll be giving MST cutting edges a try next.
The Cat ones I fitted in February were £1000 and seem to work well enough.
I'm also happy with Finnings price on the cutting edges,but their price and quality of their shank tector and tips is dreadfully lacking in putting any sort of smile on my face.
There will be no more Cat shank hardware in either of the quarries I work in.

Give the info to the Cat people and see if they get a little more responsive on other wear parts. I got better prices on dozer edges and bits after we abused the product support rep about the ripper hardware. He might give you a good deal to not try someone else's wear products.

John, unfortunately I don't have that much pull with them as I only run 1 D8 these days.Times have changed on our shores.They do show interest until it comes to pricing,then it's often the same old story.
Quality come at a cost is the sort of line,however, clearly it comes at a greater cost than Esco in this case.
I'm not saying their quality is not up to the job,it's just too expensive per hour.
Will Cat cutting edges really last twice as long as MST?,I don't know yet,but I doubt it,but they'll need to if they want to be financially equal to MST.
As for tracks,in 30 years of D4 to D8 ownership,I've never been impressed with Cat hourly costs.In saying all that,I've only run them in mixed clays and soils etc,never had a D8 dedicated to one job,such as the sandstone I'm in now.I've always convinced myself that Cat must be so expensive simply because it comes into its own on D8 size upwards in real tough conditions,but I'm not so sure these days.........
The fact is,the ITR shank tector lasts longer than the Cat tector,and the MST Easco tip lasts longer than the Cat tip in my particular application,then when you also take the price into consideration,Cat looses the race by a country mile.

I will say something positive about the Cat tip.......In the harder rock,I swear it made ripping easier on the tractor,thus more productive and cost efficient.
However,the bean counters will NEVER EVER see that,but I have concluded that if ever I get to the stage where the D8 is too small for the hardness of the rock,I'll personally pay for the Cat tip and see how it goes before throwing the towel in and buying a D9.
The Cat tip did stay sharper which would prove itself cost effective in a hard rock quarry.

Have you got rid of the 8’s and boxes, Nicky? What have you got left?

I know it’s hard to convince the bean counters, but the driver ought to be cost per cubic meter produced, not cost per hour. Also if the tip made ripping easier did the fuel burn come down also.?
Not noticeable as such.
Was burning around 37 litres per hour consistently
