pretty cool tool holder, back of the handle one full turn and it clicks into different positions, one turn to tighten it and your good to go. I tried it out with 1/2" hss and that was a little to high above center. I tried a 3/8" brazed carbide and it just needed a little brass shim to raise it up to center for the face cut. I think I'll be ok with this tool holder for awhile, I can mount 4 different cutters in it and it's not really difficult to change a cutter.[/QUOTE]
I use a tool holder like yours on my logan and I like having 4 bits in it--it works great
