It will cause confusion in-as-much-as the information is incorrect (I'm
sure many others on the group will also reply). ER collets are made to
cover the complete range of potential capacity. In the case of ER32 that
is 2mm to 20mm.

The eBay item cited is a set of 12 whereas the complete range would be a
set of 21.

Be careful of these direct from Hong Kong sales.
Read the current feedback, some is in other languages but the trend is
for customs to start checking these parcels.

When you get hit with a VAT and duty bill plus no redress on faulty
goods it's a risk you have to take. Fine on a £2 laser pointer but on
precision gear I'd like to see what I'm buying.

There is still some rubbish out there and it's bound to filter down to
the lowest priced goods. At least with Warco, Chronos and Arc you do
have some redress.

Thanks for the pointer though I was not about to purchase and used the link
to demonstrate the full range.

I used the EBay negative feedback site to check the supplier I quoted.
It seems folks are content with the collets but got caught by 'officialdom'
which pushed up the cost.
Also seems the supplier is not communicative.

Keep the price below £18 and there is no VAT - actually it's the £8 (PO)
or £10 (DHL) charge for collecting the VAT which gets you, not the VAT
itself.

There are two or three HK sellers, they seem communicative enough though
they don't reply to "it isn't here yet" comments until several weeks
have passed. You have to be patient.


Not the world's best quality, but everything I have bought has been
perfectly adequate - and the price is right.
