Questions & Answers

How do these hold up in aluminum? Will the tight flutes in aluminum plug up? (I'm talking about 1/4" dia.) ?

In the case of aluminum, it would be a waste. Get a coated HHS 2 flute or a solid carbide and spin it up as fast as your mill will allow and cut away. In response to your question, I've only used it for steel and found it to be excellent; it never clogs and consumes metal much faster than smooth/non-roughing mills. With this one, keep an eye on your stick out and travel speeds; I've snapped them before getting too far into the project.

Exceptional! Because of the end mill's geometry, I was able to cut through a round stock (aluminum 6060) with very little noise at 0

In 1018 steel, it broke

3/5

At 4500 RPM and a speed of 14, the engine broke. 5FPM. after a period of about ten minutes Little to no run out on a CAT40 collet (Er32). I looked into the origins of the tooling. Yes, that's right! I'm hoping Amazon will start displaying product origins. From now on, I'll be sticking with Niagara!.

the quality is terrible This end mill snapped after only 5 minutes of milling out some 7071 aluminum

3/5

I had to use an old i bit that I'd had for a long time. Maybe it was just a fluke, but I wasn't overly impressed.

Mini mills will love it

5/5

The only option is to use end mills. The price gouging sides are extremely effective. I have a few different sizes, and they work well and last a long time.
