156" (5/32") is the same as the diameter of the flute.
Yes, it's a full radius, but the ball end's cutting edge was rubbing, so I had to grind some relief behind it.

When used with WD40 as a cutting lubricant, this uncoated carbide endmill performed admirably on aluminum. In comparison to HSS, it can take a lot of punishment. I was aiming for quick stock removal rather than a perfect finish in the photos and video.
A coated ball endmill is shown in the photos. READ THE DESCRIPTION CAREFULLY, AS IT IS NOT COATED. When a seller posts pictures of the product that aren't the real thing, it feels deceptive.
If your project has a low arranque of viruta, a good price-to-utility ratio is appropriate.
High-quality product.
Unlike the product photo, this item is not coated. It's possible that I'll update it once I've tried it.
The bit is not the same color as the picture, but it was a good purchase with good quality.
It worked.
