Modestly priced ER collets

Just a ‘heads up’ …

Aim Tools Ltd has an ebay listing … nominally for ER25, but actually offering both ER20 and ER25 items, in various sizes.

Too good to be true ?

I won’t know until the ones I ordered arrive

Did you buy any of the "ER25 146mm" collets advertised?

I would be curious to see what geometric form they take.

Presumably they are invisible, in this Universe at least.

I checked the prices from APT and found their cheapest were not very different in price, and they also have another two grades of higher quality if required. Their prices do not include VAT, but I think their postage is free over a certain order value.

Not very different, I suppose

… except that the Aim ones are listed as Qty.3

MichaelG.

I looked at the listing and the huge quantity of photos and only saw Premium mentioned. APT list the max runout for their products.

Premium means absolutely nothing as far as a concentricity value but £3.99 for 3 is a giveaway, maybe.

"qty 3" may actually (in the sellers mind) mean "quantity" . I bought an ER20 collet from them a month or so ago and received a sealed pack of 3, on informing them of their mistake, they expected me to pay for the other 2. I ended up posting them back at my expense.

You are super 'honest' as the listing clearly says qty 3 so no idea why you sent 2 back.

… as is so often the case, I wish I hadn’t bothered posting

The title of this thread uses the phrase ‘modestly priced’ … if I was particularly worried about the concentricity, I would be shopping for Schaublin or Regofix.

I ordered mine for use on a work-holding fixture on the BCA table … so provided they clamp-up, they should be ‘fit for purpose’ … and if they arrive in sets of three, they will [as JS frequently put it] be ‘fit for purse’

Sorry if I have wasted your time by sharing my ‘find’

MichaelG.

What did it mean to you, Rob?

The listing now clearly states "3PCs".

The seller also seems confused about the difference between a collet and a collet chuck.

O.K. … if we are going to labour this

When I wrote Qty.3 that was me ‘reverting to type’

Bill is quite correct:

Feel free to play ‘typo checking’ with everything else in the listing

I will know what I have bought when they arrive.

They have clearly changed the wording of their listing since my purchase. I was expecting to receive one, and judging from their response, they only intended to supply one.

MichaelG, sorry if I offended you, I can be a bit picky sometimes, it obviously annoyed you. It seems that Aim is located only a couple of miles from me in a warehouse, they may be useful to me in the future.

Cheers,

Tony

Many of us are, Bill … it’s a problem with the English language, I think.

What you presumably know as a Collet, is often referred to as a Collet Chuck

and what you presumably know as a Collet Chuck is therefore known as a Collet Holder

Thanks, Tony … I obviously didn’t make myself sufficiently clear in the Subject line.

No personal offence taken: I was just irritated by the whole ‘tone’ of the discussion.

It’s not really like me to highlight the price of things … and I shall try to avoid so-doing in future.

MichaelG.

It would be very useful to report on your findings when the collets arrive, they may be very good. I have bought sets of the cheap Chinese in er8,11 and 25 and not been happy with some of the sizes. I buy them in small quantities just to fit the cutter sizes that are used and have had good ones from APT and Cutwel.

Just to clarify my position, Michael:

Apologies that I hadn't spotted it was you who originally wrote Qty3.

However, it wouldn't actually have made any difference if I had; I took Rob's word for it that at the time he made his purchase the listing stated QTY3, or something similar, e.g. 3PCs. My point was to ask Rob why, given the wording of the listing, he was surprised to receive three.

It seems after all from his follow-up reply that neither QTY3 nor 3PCs nor anything similar in meaning was actually mentioned in the listing when Rob made his purchase. His earlier reply at 18.13 did however cause Tony and me some justifiable confusion.

It certainly wasn't my intention to go typo-checking, much less to belittle your decision to buy what I myself would probably go for if they had any left in the sizes I want.

Under the circumstances, if you don't receive three I think you're justified in ask the seller why you didn't.

I fully intended to do that … but, as you may have noted from my earlier post, I will not be doing any tests of run-out … so my opinion will probably be worthless to you.

I have no need, and no facility, to mount them in a rotating spindle … they will be used exclusively in a static fixture, for work-holding.

At the risk of repeating myself … I mentioned them only for their modest price, and caveat emptor is implicit in that.

MichaelG.

Thanks for your clarification, Bill

Yes, I fully expect to receive three of each of the three sizes that I ordered.

If they serve my purpose, then I will consider it £11.97 well-spent.

… Until then; they must remain ‘modestly priced’ but not necessarily ‘good value’
