Help to identify this tool holder

[6ply]

I have this tool holder that appears to take a collet but I'm unsure what type. I mostly use Clarkson auto lock but have er32 when I need it. Is this tool holder worth keeping and if so what collets would it take? It's a 40int taper.

Thanks, that gave me something to Google. Does the tool holder code indicate the size of DA collet it accepts?

Yes, Kennametal dual-angle collets. I’ve got a couple of those on Int30 tapers, and I use them a lot - they came with the mill and included a couple of sets of collets. You could try Jurassic Tools if you need collets - they are usually cheap secondhand. At least as good as ER collets, and better than cheap Chinese ones.

DA collets come in 0.1mm increments.

DA180 or DA200 are the most common.
