8 Ways You're Killing Your End Mill
Feb 07, 2018 · Running It Too Fast or Too Slow Can Impact Tool Life. Determining the right speeds and feeds for your tool and operation can be a complied process, but understanding the ideal speed (RPM) is necessary before you start running your machine to ensure proper tool life. Running a tool too fast can cause suboptimal chip size or even astrophic tool failure.

My first time dry machining aluminum. having problems with ...
My two cents is don't machine it dry. A mister is a must, look into some kind of minimum quantity lubriion system. As far as tooling goes, I've had good success with garr two and three flute endmills. 143m is the 3 flute series I believe, and get them with the alumastar coating, improves surface finish and reduces the amount of metal sticking to your tools.

Minimal Quantity Lubriion and Dry Machining [ Easy Guide ]
With Dry Machining, we avoid thermal shock just like MQL, so Tool Life can be extended with modern tooling and coatings. But, the lack of lubriion is problematic for some materials. Aluminum, for example, has a chemical affinity that causes Built Up Edge (BUE).

Dry milling of aluminum
Feb 15, 2017 · Feb 15, 2017 · Re: Dry milling of aluminum. For light cutting I like solid carbide wood router bits, cheap and available at your local hardware store. Razor sharp and seem to last a long time, hours of cutting in aluminum with a cutting oil/coolant, maybe less with no coolant. Aluminum is pretty abrasive.
