I’ve got a couple of Sorby hollowing tools - the big swan neck and their smaller straight hollower. The last piece I hollowed with them was a chunk of holly root that was full of grit. I could get just a few seconds of good cuts with the half round HSS bit before it dulled. Took many more hours to finish than I would prefer!

I’ve got more of that wood and some walnut root pieces on deck for my next few projects and need to come up with a better solution. I like the tools and would like to find half round carbide bits to replace the HSS ones I have now, but I haven’t found anything other than blanks.

Anyone know where I could find pre-shaped, half-round carbide bits? For what it is worth, one measures .256” and the other is .172”. If I can’t find the half-rounds I will see if Cap’n Eddie has some round carbide cutters that will fit.
