Review: I used these bits in a Foredom jewelry engraving tool along with some StayMax Metal hollow number guided to engrave numbers in my beer flights project. Then I mixed powdered turquois in resin to make these numbered holes.
Review: UPDATE: I upped my rating from 2 tp 4 stars. Customer service was very helpful and responsive. They actually contacted me when they saw my original review. I found that my spindle speed was too slow. Obviously it depends on the material but these bits have to be spun pretty fast and the depth and feed rate must be shallow and slow as well. My mill only spins at max 2800rpm. So I spun it at 2800rpm and took a more shallow cut along with a slow feed rate and these things cut pretty decently. I assume they would work better at an even faster spindle speed. They are still very brittle and will snap if you apply to much side pressure. Overall they did the job I needed them for. Item came packaged well and they looked good. I ordered the 1/16th size and these things snap at the slightest pressure. I almost messed up my project so I had to discontinue using them due to them snapping so easily. I tried another set I had and had no issue.

And possibly that’s sold. I break others that cost 2-3x and these will rip through 6-4 grade 5 TI , full 100% slot at full doc of .190”. .20 thou doc per pass , 8500 rpm , 9.4 ipm. I also use their bull nose end mills for facing ti and they just do not dull.
