Electroplated diamond is extremely sharp initially, so it’s effective for roughing operations where you want to remove a lot of material quickly.
Immediate cutting (no run-in period)

The diamond layer is exposed at the surface, so the wheel doesn’t need dressing/“conditioning” to become effective.
Excellent wheel sharpness / profile definition

Helpful when graphite shapes require accurate edges, radii, or profile grinding even during roughing.
More consistent cutting behavior

Many bonded systems (resin/metal) can shift from cutting to rubbing as the wheel loads or loses effective grit. Electroplated wheels often stay “cutting” longer in light/moderate duty roughing.
Less bond wear

Since diamonds are plated directly, you don’t lose grinding performance the same way you can with some bond/matrix wear mechanisms.Good choice for precision roughing.
