Maybe it's a flat belt like my pin router ?

Thankyou guys!

I am going to use it for a cnc spindle drive using a brushless RC outrunner.
To be honest i havent got a clue about which type of belt i need but i was hoping that the supplier could help me out.
The motor is going to run at max 4800 rpm and the spindle about 2,5 x 4800.

Got that on my list!! What size motor do you plan to use and will you regulate it with a servo tester? Also be interested in power source please. LiPo`s?

I am going to build two spindles. One with a belt drive for milling MDF, wood and softer materials. The other one with a direct drive for aluminium.
I will use a 220V power source. Right now im looking at 12-18V and 500 W. I will use as powerful outrunner motor as the power source can handle.
Maybe about 250-300 kv. That will give max 5400 rpm direct and more with belt and pulleys.
Yes, i will regulate them with an ESC and a servo tester.
