.017 مطحنة نهاية كروية طويلة المدى بوصول .075″

I grabbed the .017 to clean out deep slots in aluminum and the 0.075 inch reach gets down in there without rubbing the shank. Tip is tiny but it cut clean and didn't snap, which I half expected at that size.

The relief grind on these makes a noticeable difference in surface finish compared to standard ball ends. I've been cutting deep 3D contours in aluminum and the .075" reach gives me the clearance I needed without chatter.

I was worried the .017 tip would snap on my first deep pocket job, but the relief grind actually holds up fine in aluminum. The 1.3mm flute length clears chips way better than the stubby bits I was using before.
