Bond and Grit Starting Point

Floor hardness	Bond	Opening grit	Why
Mohs 1-2	Hard	#30 / #16	Controls wear on soft or green concrete.
Mohs 3-4	Medium	#40	Balanced cut speed for general commercial slabs.
Mohs 5-6	Soft	#50	Exposes fresh diamond faster on dense concrete.
Mohs 7+	Extra Soft	#80	Reduces glazing on very hard aggregate.

Coating removal

PCD or aggressive metal tooling first, then metal bond cleanup.

Ask for a before/after scratch photo from the test pass.

Grinding

Use the bond table by floor hardness and keep passes even.

Move to the next grit only after scratches are consistent.

Polishing prep

Avoid skipping transition grits before resin pads.

Confirm the floor is flat before moving into higher grits.

Surface prep

Prioritize stable scratch profile and predictable tool life.

Choose a conservative first set when hardness is unknown.

QC Proof to Request

Request EZ-Change holder fit check, segment height measurement, and inspection video.

How do I confirm EZ-Change fit before ordering?

Send the grinder model, tooling plate photo, and current holder condition so attachment fit can be checked before the order moves forward.

Can I request QC proof before shipment?

For qualified orders, request inspection photos or video covering label, segment height, quantity, packing count, and shipment mark.
