I've read through some threads here on tbn and looked around on ebay and such but I'm a little confused about my options. I've recently purchased a used phd with an auger that has the twisty pilot bit, but completely smooth cutting edges. It's not doing so hot in my rocky area. I don't want to buy one of these $2k rock bits, nor could I even if I had to. I see listed on ebay Jeffery and Pengo teeth but I'm not sure if they only fit certain bits? I'm needing a smaller diameter bit, so I'll probably go to tsc and get the 6". Can I modify the blades by simply drilling holes and bolting these teeth on?
