New ER 25 Modular Collet lholder

John Stevenson gave me a lead to this supplier of tooling for model Engineers.

They have some interesting stuff and am sure more will be added as the company expands. They are called Emvio https://emvioeng.com should get you to their site.

Having a Tormach mill with an automatic Tool Changer I need plenty of ER collet holders but importing them from the USA makes them very expensive. The collet holders I have from them are ER20. A look on the Emvio site showed that they have ER25 & ER 32 Collet holders with shanks suitable for my Tormach spindle.

The ER 25 holders are £22 each , I decided to get three of these and at the time I applied for the Easter discount but unfortunately the code didn't work when I tried the number while checking out from their webshop. There was a place on the payment screen where you could make any comments so I mentioned that the discount code didn't work for me.

On Receiving the note on my order the Proprietor George offered me an extra tool holder for £5 to make up for the loss of the discount which I thought was very reasonable.

The holders arrived today, They are extremely well finished and well packaged in plastic bags inside a hard plastic box with plenty of anti corrosion oil on them.

The Holders arrived this morning so I thought I would give them a try in the mill. I needed to mill a bracket from 1 1/4" thick Aluminium alloy using a 10mm End Mill. The previous bracket I machined using the same cutter was ok but there was some chatter from the cutter but much to my surprise when I used the new ER25 Collet Holder there was absolutely no signs of chatter.

I'm not sure why the chatter disappeared with this holder, maybe they get more dimensionally correct than the Tormach ones or maybe them being slightly larger and having more mass they dampen the tendency to chatter better, Either way I can say I am well pleased with my purchase. Another bonus is that I will be able to hold some of my larger end mills now.

For any Tormach owners in the UK here,s a cheaper way of getting collet holders for your machine.

I notice from their shop that they sell Stepper Motion Control boards, Tool Holders and Collets, Ballscrews and 3D printers.

I should add that I have no connection with this company other than being a satisfied customer.

Yin Sheng Machinery (IGeShi brand at cnccollet.com) used to supply ER20, 25 and 32 TTS collets, with or without the ATC groove at $157.00 for 10 of the ER20 variety (complete with nuts).

Comments from the wider community claimed comparable run out between these, Darkon and genuine TTS collet chucks on a direct comparison test.

They are not currently listing these collet chucks, although they were still listed a few months ago, but I am sure if contacted, they would be prepared to do another run.

Hi George,

A point well made, and one I have often made myself on other forums.

I could not recall the shipping price from the last time I saw them listed, and had mistakenly recalled this to be free :D

£10.00 vs £22.00 per item as you so rightly say is not always the full story.

From a personal view point, having a VAT registered company, I tend to overlook the VAT element as I can claim this back, I would however still have to pay the duty element, which, as you state is chargeable on the product + shipping price and don't forget to add the £10.00 handling fee for the post office

I do however regularly stock up on items from US suppliers, not always available here in the UK, or simply cheaper, whenever we go on holiday to the USA - my wife draws the line at lathe chucks and milling vices though

The price for a genuine Tormach holder (ER16, 20 or 32) is $34.75, which works out to around £22.70 (which I can pay when on holiday) with $16 shipping (for 10 via USPS), so for me there is no real saving over the genuine article.

I will agree that for UK based, non VAT registered customers, especially when a voucher is available, these are indeed a good deal.

You also have to take into account that duty coming in from the States isn't the same as China.

China is 2.7% , the US is closer to 17%

I was talking about holiday purchases, where provided the total import value is less than £270.00 per person arriving from a country outside the EU by boat or plane (£1080.00 for a family of 4) there is no duty or VAT to pay.

The shipping costs to the UK from Tormach for 10 units would be around $76.00, plus all of the associated duties on a combined shipment price of $347.50+$76.00=$422.50 (about £280.00), +17% duty, + 20% VAT + £10 = £395.00 or £39.00 each - so not viable compared to Emvio.

Just checked on the price of the Darkon Industries copies and these are actually more expensive than genuine Tormach items at $51.34 CAD (£27.23) before shipping!
