1.0mm 公制長刃球頭銑刀 – 刃長16mm

The relief grind behind the flutes is a game changer for deep cavity work — I could plunge straight down without the shaft binding up, which was my biggest fear with a 1mm tool. It’s held up through a few hours of aluminum with no visible wear.

Finally, a 1mm ball end mill that doesn't snap the moment you reach into a deep pocket – the 16mm reach lets me clear out corners I couldn't touch before. The solid carbide holds up well through a few passes in aluminum, no chatter.

That relief grind after the flutes is a lifesaver—I could plunge into a 3mm deep pocket without the shaft rubbing at all. The 16mm reach got me into a spot my shorter bits couldn’t touch, and the carbide held its edge through the whole job.
