Difference in auger teeth?

[M59]

I need to replace the teeth on my post hole digger and the fish tail also. There seems to be a lot of choices. Anyone have opinions on what to get? What works well for pretty hard rocky soil? It takes pengo teeth. But I think if I put on a new tip/fish tail it can change.

Thanks in advance for any advice.

A bit more detail on what you mean by pretty hard rocky soil would be helpful. Rocky soil can take lots of different forms. This is what I deal with in hills of NC. When I get into this stuff then ONLY carbide tipped tip and carbide bullets on the first flight and then hard face on the flight edge for next foot.

If your talking small bank run gravel rocks then forged spade teeth ( Pengo / Esco ) will dig well. Depending on how your existing teeth are mounted to your existing post hole auger will determine what your choice for teeth are UNLESS your willing to replace the root and the tooth with preferred item.

The choices for teeth are huge so have fun googling BUT check what is on your auger first.

Here’s a 6” and a 9” auger with pengo carbide teeth for shale or clay. They work reasonably well in shale, excellent in clay.

I would hope so. Adding those heads onto an auger nearly doubled its price.

I find that it's mostly the wisdom tooth that wears in rock and clay. If you can weld you can always put some beads on those teeth.

If your trying to drill through bed rock I wouldnt bother. Just epoxy in something.

I have gone thru a couple sets of standard pengo teeth, 1 set standard and 1 set w/welded on beads in about 50 holes. My auger doesn’t have any down pressure, just me with the digging bar as a lever off the back. Holes on average take about 15minutes to dig. Ground is dry and hard this time of year and is not solid rock or bed rock just mixed with rock. Teeth just get shaved or filed off looking and become useless. I flip them over after about 15 holes and they work again for about 10 more holes.

stumblinhorse,

I don't understand why you are having very high tooth wear. Very sandy soil can be aggressive on dirt teeth if they are standard cast teeth instead of forged. Is it possible the teeth are made of chinesium?

I will take a picture of the rock and dirt augers I use ( both 12" ). Both have been used for hundreds of holes with virtually no tooth or flight edge wear. I will look up tooth replacement info and post here later today.

I just looked at the set off the auger. They are forged pengo aggressor 40/50 made in the USA. I am sure they wear down since it takes so long to make a hole. Kind of a catch 22.

AugerTeeth | 35 Series Auger Teeth if the link works... first few teeth are what now have & work great. "Pengo 1336L Carbide Tipped Tooth" came with the used auger. Absolutely useless in Colorado clay due to being so obtuse on the cutting edge. I'm sure they last WAY longer & do gravel better. But they don't do clay.

"Dirt" 60 miles away is called the Rocky Mountains & mostly granite. Totally different than what I have. Conditions vary so what works for me may not work at all for you 60 miles away much 600.

stumblinhorse,

Just looked at the augers. All made by Premier and all the spade teeth are marked Premier 00200. The tree planting auger hasn't seen much use so teeth can be read.
The auger bit is Premier CDR for rock auger and CDC for dirt / dirt gravel.
