拋光打磨頭（大/細）

Finally, a bit that leaves acrylic feeling glass-smooth without those annoying chatter marks. The large surface area lets me cover more ground quickly, which saves me time on finish work. Exactly what I needed for my last set of salon nails.

I’ve been using this bit to finish acrylics and it leaves a smooth, almost polished surface with no scratches. The fine grit takes off just the right amount without digging in. Definitely a must-have for professional work.

Didn't expect a bit this large to finish so cleanly, but it smooths a fully cured acrylic surface in a couple of passes. Runs true with no chatter at higher speeds, which matters when you're doing the final polish on a set.
