This implies a 2mm TAG (minimally I would hope)
This is the path that lead you to believe it is proportionally substantial (visually):
TAGGING is a safety implementation/feature. For that reason alone, WIDTH should reflect a MINIMUM, not the peaked tab shown above in the machined aluminium due to the TOOL diameter (4.22 - 6.2 = Ah, no flat as implied by all other visual tools) . The WIDTH looks to be defined at the base; 8.3mm - ToolDiameter (In this case was 6.2mm) = 2mm. I find this slightly misleading from a satety POV.
And yes, I know I could make the TAGs wider and this would not be an issue; I would rather not have someone (who uses TAGs infrequently) learn that lesson the hard way.
