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.

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:
High Speed Steel End Mills (HSS) HSS end mills come at a cheaper price, but do not offer the tool life or speed capacity of solid carbide end mills. Cobalt End Mills. Cobalt end mills come at a higher price than HSS but provide better wear resistance and toughness.
Ahidley, here's my rules of the thumb for settings feeds and speeds for both HSS and carbide endmills. HSS SFM's. Mild Steel 100. Free Brass 300. 6061 Aluminum 400. Now for uncoated carbide tooling multiply those SFM rates times 3, for coated carbide multiply times 4.

You can now get excellent quality Made In USA carbide (and HSS) end mills for very attractive prices from JTS Machinery & Supply of Mentor OH, Cutting Edge Supply of Colorado Springs CO, KBC Tools, Enco, and many others. Just avoid the "import" branded ones and you'll be fine.
Dual heat treatment (DHT) effect is analyzed using the machining of Al6061-T6 alloy, a readily available material for quickly finding the machining properties. The heat treatments are conducted twice over the specimen by the furnace heating before processing through CNC machining. The HSS and WC milling cutters are preferred for the diameter of 10 mm for the reviewed rotational speeds ...
Modeling of the End Milling Process for Aluminum Alloy AA6061t6 using HSS Tool 1143 The t wo -flute tool is selected in order to avoid chip clogging in the tool flutes.
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.
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.
Cobalt HSS Square End Mills, regular length, two flute for machining aluminum castings, cast iron, carbon steels, alloy steels, and die steels.
Turning speeds are adjusted to the feed rate of the mini lathe (0.004/rev.), a depth of cut of 0.040, and a tool life of 180 minutes. Material. AISI/SAE/ASTM Designation. HSS. Feet/Minute. Carbide. Feet/Minute. Free machining plain carbon steels (resulfurized) 1212, 1213, 1215.
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.
Cobalt HSS 2 Flute End Mills, Regular Length, Center Cutting for 6061 aluminum, 7075 aluminum, aluminum castings. TiN, TiCN, TiAlN coatings available.
For a 1/2" HSS end mill in 6061, you should be running about 3,200 RPM. Stick with the HSS, it's a lot cheaper and easier to find. JR 12-02-2005, 06:25 PM #7. dsergison. View Profile View Forum Posts Diamond Join Date Oct 2003 Location East …
Skip the 5/8" and get a 3/4" corncob rougher. A generic coated HSS mill will work fine, get a centercutting version TIN or TICN coated, or best would be a 3 flute aluminum specific version. With the smaller end mills make sure the shanks are long enough to extend all the way through your collets.
End Mill Composition High Speed Steel (HSS) Provides good wear resistance and costs less than cobalt or carbide end mills. HSS is used for general purpose milling of both ferrous and non-ferrous materials. Cobalt (M-42: 8% Cobalt) Provides better wear resistance, higher hot hardness and toughness than high speed steel.

Aluminum alloy 6061 was widely used in aircraft structures, yacht construction, automotive chassis, etc., For machining the Aluminum alloy 6061 high-speed steel (HSS) end mill cutters were used.
This end mill is made of High-Speed Steel (HSS) which makes it super strong for any aggressive work. The set includes six different sizes: ⅛ inch, 5/32 inch, 4 inches, 5/16 inch, ⅜ inch, and ½ inch of end mills to fulfil your requirements. UDK end mill bits are mainly suitable for side milling, end milling, and finish machining.
Milling Speeds and Feeds Charts. The most important aspect of milling with carbide end mills is to run the tool at the proper rpm and feed rate. We have broken these recommendations down into material categories so you can make better decisions with how to productively run your end mills.

Ductile, corrosion resistant, conductive, and abundant. Aluminum is a mainstay of today's aviation, medical, electronics manufacturing, and many other industries. It's light weight and high machinability can be both a positive and a negative for machining purposes. On one hand, the machinability makes high speed machining achievable with little harm to a drill or tap.
