I have been using some old Kennametal, straight shank tapping holders. The shank is 20mm in diameter and the overall length is around 185mm long.
I think the collets we use are the DA200 (J) type collets with the cut out in the bottom and square end. Can anyone confirm this collet as shown in the photo.
Also does anyone know of a similar or the same tension and compression tapping holder that I can still purchase in the uk and collets to suit. Most of the tapping is for M3, M4, M5 and M6 ISO.
I have sort of hit a brick wall with trying to locate information on these holders and collets and appreciate any help and info you can give me on them.
I have tried them, I want something similar to what is in the photos or it means changing collet systems etc..
We have used them, they are a Kennametal / Erickson holder with 3/4" or 1" shaft and a DA (J) collet system and are interchangable
you have a "SOMMA" distributor in the UK -see....http://www.dpautomatics.com/
