Tool Room Grinding Wheels

In engineering and manufacturing, a Tool Room Grinding Wheels is everything related to tool-and-die facilities and methods, in contrast to the factory floor and production line activity.

For people not familiar with these fields, in order to understand the specialist usage, some explanation is needed: Within the general field of machining, there is a rough but recurring division between
(A) Toolroom practice and
(B) production practice (the making of large numbers of duplicate parts)

It is the difference between manufacturing itself and the tool-and-die work that is done in support of the manufacturing.
