HTC grinding shoes, with different shapes segments. Round buttons, arrow, rectangular bars, single or double segments for HTC floor grinder.  But what is more important, especially in the initial grinding steps, is the bond or hardness of the tools. 

Bond: super soft, soft, medium, hard, super hard 

Hard concrete requires softer bond to prevent glazing and to allow new diamonds to get easily exposed for maximum grinding.
Soft concrete requires harder bond, so it can last longer (soft bond also works but it will wear out too fast on soft concrete).

Grit: 6#, 10#, 16/20#, 30#-200#, 350/400#

 For example, if you start with 30 grit, the next grit is 50 or 70, then 100 or 120, 200 or 220, 400, 800, etc.

With full experience, SUNNY will provide you suitable bond, right tools.
