Thanks for the info, but I’m specifically looking for the exact one in the 5 pack. I bought some other 1.5mm x 12mm double flutes and the cut on those is worse and off somehow. So I need the single flute spiral and I’m having an incredibly hard time finding that one anywhere else.
The one I’m looking for is in the middle of the picture. I’ve combed amazon and amanas site with no luck finding a match. For now I’ve switched to the 3.125 cutting diameter, which works as well, but wastes more material and I have some pieces I can’t cut due to the larger diameter.
I’ve played a little with the bits I initially bought as a replacement, but for whatever reason, I just cannot get them to work correctly. I’ve tried telling luban that the bit is slightly smaller than 1.5mm, but that doesn’t seem to help.
I just know the bit style I was using worked great and the puzzle pieces were a bit snug, but they still fit together immediately after cut and removal of tabs. But the initial replacements will not fit together immediately after cut and removal of tabs without heavy sanding.
I’ll have to do some research on different bit styles/purposes.
That’s an up-cut bit. The chips are pushed up during the cutting process. For a better surface finish, choose down-cut bits. They’re not as good at chip removal as up-cut bits, but they shear the surface downward during a cut, leaving a cleaner cut line.
