2.5mm 公制長延伸球型端銑刀 – 延伸19mm

Finally a 2.5mm ball end that can actually get deep into a pocket without the shaft rubbing. The relief grind after the flutes makes a huge difference when plunging into tight spots.

That 19mm reach really saved me when I was cutting deep into a block of aluminum and my standard bits just couldn't get there. The ball end leaves a clean finish, and the solid carbide feels much sturdier than I expected for such a tiny diameter.

The relief grind after the flutes is a real lifesaver—I can plunge into deeper cavities without the shaft rubbing or chattering. It's rigid enough that I didn't notice any deflection even at full 19mm reach.
