Hi all, does anyone know if the Clarke collet chuck is to any particular standard, they don't seem to sell a range of optional size collets, looking for some imperial ones, they are longer than say ER collets.

I have an ER chuck for my mill, but bought this Clarke one when I had a CL500M lathe, thought I would keep the Clarke one to use in my later Warco lathe.

Very hard to find individual collets now, ARC did do them at one time but stopped maybe 8yrs ago. I got one with a set of imperial collets back in 2007 when I bought my X3 from Engineers Toolroom and added some Metric ones from Arc when they had them as clearance items.

Have a look at post No. 16 here:

There, they are called Q24-16.

Life is very circular. That site also references this site:

where the drawing above first appeared.

Drawing appeared before that on ARC's website where I snipped the image from.

Note the Q24 are shown as 10deg, the Arc as 8Deg
