HSK taper

Machine_taper#HSK_taper says:

 The shank is short (about half as long as other machine tapers), with a shallow taper (a ratio of 1:10), and slightly too large to allow the flange to seat fully in the socket.

But the drawing right beside that paragraph shows a "1:9.98". Machine_taper#/media/File:DIN_69893_hsk_63a_drawing.png

Which is correct here?

Or maybe I'm misunderstanding something and that the two values are intentionally different. OptoFidelty (talk) 02:44, 4 May 2024 (UTC)[reply]

All the refs for current standards I see are 1:9.98. For that, "1:10" seems like a simplified approximation. I agree that we shouldn't make an approximation when stating outright what a standard is. DMacks (talk) 03:45, 4 May 2024 (UTC)[reply]

There was a hidden note that clarified it. I've unhidden it. Greglocock (talk) 02:13, 5 May 2024 (UTC)[reply]
