طقم رؤوس ألماس مدببة مستديرة 3 قطع، ساق 3/32 بوصة

Finally got around to testing these on some hard porcelain tile—the 1mm tip is tiny enough for precision detail work without chipping the edges. They seat firmly in my handpiece and haven't shed any grit during use so far.

The 1.4mm and 1.6mm heads handle fine detailing on ceramics without any chipping, and the 3/32" shank fits my rotary tool snugly. Even after a few hours of use on glass, the diamond coating hasn't worn down at all.

Bought these for detailed engraving on some ceramic tiles, and the 1.4mm burr made clean, precise lines without chipping. The stainless steel shanks hold up well under constant use. Exactly what I needed for hobby work.
