3피스 다이아몬드 버 세트, 3/32인치 생크

I needed a tiny ball bit to clean up a ceramic glaze detail, and the 1/16" diameter ball in this set worked perfectly without chipping. These shanks fit snugly in my rotary tool, and the set covers most shapes I need for fine work.

The tapered bit with that 1/32" tip got into the tight little grooves on my metal engraving project without slipping like my old bits did. All three shapes fit snugly in my rotary tool and haven't loosened once, even after a solid hour of grinding on glass.

The ball head glides through ceramic glaze like butter, and the 3/32" shank fits my rotary tool without any wobble. I’ve used all three shapes on glass and metal this week, and the tapered tip’s precision is exactly what I needed for tight corners.
