Auger Sizes

More on this -- I see I can buy carbide masonry bits around 40" long and 1.5" diameter for around $270. I'd have to make some kind of adapter if I wanted them on the tractor auger, as they have special splined shanks to fit a rotary hammer tool. Not sure I could handle them in a rotary hammer drill by hand, especially pulling back out.

I have a pile of augers that are 5 long and around 3 in diameter. The have 1-5/8 hexagonal connections on the ends.

Good bits for them are around $60 each and the auger sections are around $200 each. You would need an adapter made to fit them on a tractor auger. I get them at Mobile drill.

The bits you want are the two prong mining bits.

I have a BX2660 so same engine and PTO size as original poster . I went with 9 inch auger and in clay have got that badly stuck and the tractor overwhelmed. Large pipe wrench and pipe on handle to reverse it out. I hate to think what a bigger auger would be like . Keep in mind that even if your post size is tight for a 9 inch …..you can have more wiggle room to get them vertical by moving forward and back with tractor while auger is in ground to make upper part of hole larger.

Does anybody know where to get an auger smaller than 6"?

My soil is often so hard I can't even get the tip started - I mean the casting that looks like the end of a wood screw. I have round river gravel cemented together by clay. Many years ago I did a painfully big project with a 4 handle handheld auger and 3 of us, and we were actually using a masonry bit to drill pilot holes to get it started.

I'd like to find a 2" or so drill bit long enough to penetrate a couple feet into the ground. A masonry bit might work, or perhaps a drill bit intended for metal.

Another possibility would be more weight on the assembly. I haven't had a convenient point for hanging weight so perhaps that what I should try next.

Here is one for 30 bucks.

Wow. Looking through the products at https://mobiledrill.net/wp-content/uploads/2019/05/CFA-Pages.pdf now. Seriously impressive. Of course it should have occurred to me, people drill through all kinds of rock and wicked soil. It's expensive but I kind of want to go for it just to mess with augers this serious.
