I did notice them advertising that a couple months ago, but they didn't seem too keen on publishing details.
However, they do have it listed on the website now - https://www.cutwel.co.uk/tool-holdin...e-tool-holders
A friend who bought my old benchtop CNC is looking at buying a holder for his larger mill to facilitate easier tool sharing between machines, I thought I'd post the info here as people have asked for this tooling.
Coventry Engineering also have them listed on their website.
Not sure how they compare price wise to Cutwel, as Cutwel's website is not showing any products in the category at the moment.

They were there 2 days ago, they may have sold out.Quote:

Note these prices exclude VAT. Given that I have a power drawbar, I'd rather have several normal holders than one of these.
Having written all that, they seem to have suddenly reappeared on their website today. https://www.cutwel.co.uk/tool-holdin...e-tool-holders
Note they are not recommended for heavy cuts. That pretty much ended the thought process for me.
In my experience, the best price for std ISO40 tooling is currently APT Tools (or Cutwel when they are on offer).

The Coventry system is smaller than BT30 or ISO 30, and was common on some educational and hobby mills, I run BT30 and wouldn't be using an adaptor down to Coventry, or suggesting anyone else does so, there is no choice for some who have a mill where this was the OEM fitment, the original supplies have all but dried up if you actually try buying one.Quote:

On a similar topic, if I were to buy a new mill, what spindle taper should I look at? I'm seeing old R8 anglophile but MT / BT / HSK on the continent?
I appreciate this article is a bit serve serving, but reading between the lines, I'm getting an HSK buzz :)

Depends really on how ridged the machine and how aggressively you want to cut, plus how deep your pockets are.?Quote:

Also, need to consider the strength of the machine, the main advantage of HSK is the rigidity it provides allowing more aggressive cuts to be made but if the machine doesn't match the taper what's the point.?
I get the feeling that 40 taper is the most readily available and cheapest for medium sized machines. 30 taper costs more due to less industrial usage. HSK is for big and really high speed machines and big pockets - unless you are running >10krpm in a large, powerful spindle there's no advantage for the likes of us. R8 is a US activity and more readily available over there but it's only really suitable for small to medium machines - created by Bridgeport for their machines.
I can get a wide range of good quality ISO40 tooling for my Shizuoka for around £20-25 a pop. My Bridgeport has ISO30 and the holders are more difficult to find and cost a fair bit more. I don't get close to challenging either of those with the work I do.
