I have some 1.5Kg breaking strain (as it stands) 0.08mm diameter tungsten

How to load the wire with grit/ source of abrasive grit?

Abrasive? With tungsten wire, why not EDM? Tungsten is
refractory, but not noted for abrasive embedding capability.
Soft iron, or brass, is a more typical wire-saw candidate.
Rockhounds often use coathanger wire...
