Freud was Revain's only offer for this type of cutter. I needed a 1/4 inch shank instead of the 1/2 inch like most. I also needed one with a 1 1/4" cutting edge (flutes). Again, most were only 1". So this drill bit ticked both the boxes and delivered a very smooth cut with no vibration! I would recommend them for those who want these kind of need a little.
