That machine has an  MT3 taper for the mill spindle so an R8 will not fit, you should be looking for an ER type collet chuck with MT3 shank

He already has this set for the clarke mill, i think he wants to know what type of collet is used in the set, so he can buy an r8 holder for them for his denford mill.

Just measure the outside diameter of a collet if it 32mm then the size is ER32

Ok I have mesured the collets and they do not go with any specs I can find or in the ER system.
The Dia is 24mm with a lenght of 45mm

So it looks like I am no further on that I was lol oh well back to the drawing board

to use them, it looks like you're going to have to make a holder out of a soft ended r8 blank using the nut and collets from your set.
