Hello,

Usually 2 flutes endmill perform well in all situation.
For some material they are specialized endmill.
Wood : usually straight endmill are used such as http://www.bois.com/decorer/bricoleurs/ ... -courantes
Aluminium : special angle endmill such as http://www.cncfraises.fr/198-carbure-2-dents-alu . Some Fast steel (HSS) endmill are sometime better, but I only use carbide for now.
Acrylic and plastics : i think 1 flute endmill usually works best with fast rotary tool as the one on the Shapeoko (they reduce heat and prevent it from melting)

Where exactly are you in Europe ?
I usually buy on the above site (from France)

We don't have many shops listed yet, but we're trying to build up a list of shops by geography: http://www.shapeoko.com/wiki/index.php/ ... #Materials

IME, Sign and glass shops (and esp. glass shops which do signage) are willing to special-order and sell sheet goods.

In the U.S. there are a number of lumber yards, even a specialized site for finding them: http://www.woodfinder.com/

There was some discussion of sourcing material in the U.K. here: http://www.shapeoko.com/forum/viewtopic ... 52&p=10021

The Dremel uses tools with 1/8" shaft, which is approx 3.2mm.

As for buying tools online...
Drillman1 on eBay is always a cheap and dependable source.

Just check out your country's import tax rules. Most countries has a limit somewhere and packages below that limit is exempt from taxation.
As long as you stay below the limit, and the seller doesn't do something stupid(such as ticking the 'Gift' box and setting the value as $5), the customs people shouldn't make any problems.
(All my packages from Drillman1 were marked properly and passed through Norwegian customs without a hitch. On the other hand, they've been known to return entire shipping containers with packages from dx.com without even bothering to check the contents. They just assumed, rightly, that the customs declaration was wrong)

I have recent experience with this, and was thinking of asking about a vendor feedback forum in which to post but I'll save evryone the trouble and post here instead.

I ordered 20 end mills from supermario-au on eBay as they're mentioned somewhere on the wiki and they seemed cheap. Well, after 3 weeks the mills arrived but the quality is, as usual questionable at best. I ordered carbide 2 flute 1/8" end mills, 10 of them ball (round tip) and 10 with the usual flat tip. Even among mills that are supposed to be identical they vary in length by up to 4mm. I don't suppose this matters so long as the length of the cutting edge is the same. The biggest issue is actually that most of the mills show signs of corrosion - mostly pitting and a little rust - which makes me wonder what they made these things out of. They mills are obviously sharp but not scary sharp, I can roll the cutting edges on my fingertip and they won't cut skin. Just for comparison with my next experience they sent the mills in an envelope and used broken plastic mill cases with random scraps of dirty foam inserted to keep the mills from rolling around. Anyway, cheap enough and probably OK for use in soft materials such as extruded polystyrene which is what I bought them for.

I then ordered from precisebits.com in the states. Their postage was expensive which was a bit off putting but the package arrived in just 2 days and luckily no taxes to pay. In contrast to my experience with supermario-au this order arrived in a sturdy box, sealed with fibre reinforced tape and marked with day glow orange 'fragile' stickers. Inside the mills I ordered were kept neatly arranged in high quality mill cases which are tough to open so pose no risk of opening in the post. Despite this precisebits had put an elastic band around each case to make sure it wouldn't open in transit. The mills themselves are works of art, all absolutely identical, no corrosion at all and they are scary sharp! They do cut skin when rolled on the fingertip. They also have depth rings fitted which might prove useful in the future.

Obviously we get what we oay for and precisebits is much more expensive than supermario-au but precisebits is clearly run by perfectionists and they should be justifiably proud of their products and service. Dealing with supermario-au I guess it's just another line of cheap stuff from the East. I wouldn't buy from them again but I'm sure the tools will be adequate. I bought from precisebits in the US instead of their European distributor, frezycnc, because frezycnc did not have stock of some of the things I needed, but it's good to know that the same tools are available in Europe. Reading between the lines I suspect the same manufacturer is behind the tools that precisebits and drillman1 sell. Both state their tools are made by an American company.
