Attacking Aluminum: a Machining Guide - In The Loupe

End mills for aluminum are often available in either 2 flute or 3 flute styles. With higher flute counts, it would become difficult to evacuate chips effectively at the high speeds at which you can run in aluminum. This is because aluminum alloys leave a large chip, and chip valleys become smaller with each additional flute on an end mill.

Aluminum Roughing End Mill: Recommendations? | The Hobby ...

These guys claim as much as 20 times tool life in 6061 with no aluminum build up on the tool. That's beyond interesting. I found this end mill which states that it's for HEM, so I'm not sure it's as useful in a manual Bridgeport type mill. But it does have an aggressive chip breaker and might work nice as a roughing end mill for aluminum:

End Mills. The Essential Beginners Guide.

End mill life expectancy - Google Groups

In my manual milling I mostly use HSS end mills, and I rarely break one that is over 1/16". My go-to AL end mill is a 1/2" two flute high spiral and that will tear through 6061-T6 AL at ~2,000 RPM and something that has to be pushing 100 IPM for a side cut of .5" depth x 0.020" width.

Carbide endmills Vs HSS endmills? - The Home Shop ...

Please be more specific. RPMS are directly related to diameter, thus 2000 RPM with a 1/4 inch end mill is WAY differant than 2000 RPM with a 3/4 diameter. Also are you talking about solid vs with inserts? I've always just looked at a HSS chart and what ever the RPM recommended was I would double it for carbide as well as feed.


Extra Long End Mills For extra long end mills the SFM should be reduced by 25%. Cutter Direction Cutter direction should be in a climb milling direction whenever possible. Con-ventional tool paths may be employed when the tool is in use on older manual equipment to minimize backlash or to remove scale to reach the softer parent material underneath.

HSS / TiCN endmill vs aluminum (Speed check)

I'm running a 1.25" three flute end mill (HSS / TiCN) in plain-old 6061-T6 Aluminum. Is 590 SFM too much for HSS? I ran a couple tests (slotting with 0.75" depth) in some scrap and came up with 590 (1800 rpm) 20 IPM (.0037 IPT). The chips look great and clear the slot nicely. The finish is acceptable and the machine is happy.
