Thanks for the reply, are there any pulleys with a 10 mm hole already in the middle,or I am missing something,I can find only with 6 and 8 mm HDT5 pulleys at beltingonline.

Not sure if this helps, but I just ordered some on eBay in US. from China:

https://www.ebay.com/itm/HTD-5M-20T-...72.m2749.l2649

I figured they wouldn't ship until after Chinese New Year, but they are supposedly on their way. Obviously, I can't yet speak to quality...

Regards,
Wallace

They quite often just have pilot hole but have you asked them if they can bore them out for you, don't forget grub screws

I have just checked http://www.beltingonline.com/20-toot...20-5m-15f-7776 there is an option for the boring and grub screw holes. bit expensive thou , not hard to do.

I usually let them do it, its a bit of faffing about that i can do without for the sake of 3 or 4 quid, plus getting the grub screws as well :)

Thanks guys, I just login to report that I saw that there is an option for modifying bore etc. and see your answers!

I found those at aliexpress, they are made from aluminum alloy come with 10mm bore and two screw holes.
I am going to use 1/1 ratio for X Y and 1.5/1 for Z , are those any good, anyone has experience with those?
Any suggestions about the belts?

**Nickhofen** · 24-02-2018

Just notice that they seems to be the same with those Wallace suggest ,with no shipping cost...

Hey Nick!

If you have the right length on your end machining on the ballscrew I think it's better to use pulleys with a shoulder with the setscrews and not the ones with bored out teeth.
I think it's kinder on the belt :)
