Yes, they need different beads. Concrete wire uses fast-cutting, medium-bond beads that handle steel and aggregate. Granite wire uses hard-bond beads with higher diamond concentration to cut tough, non-abrasive stone without shedding diamond too early.
| Factor | Concrete Wire | Granite Wire |
|---|---|---|
| Bond | Medium | Hard |
| Beads / meter | 30–40 | 28–32 |
| Cutting style | Aggressive | Steady, controlled |
| Best for | Demolition, rebar | Quarrying, block cutting |
A:It will wear quickly and cut slowly — concrete is abrasive and the hard bond dulls against it.
A:Only for short jobs. The medium bond sheds diamond too fast on granite, so the wire wears out early.
A>It depends on material and feed. A matched wire on granite can cut hundreds of square meters; a mismatched one may fail in hours.
Match the bead bond to the material — never compromise. Use the Diamond Wire Saw for Concrete — JOY-WS-C for demolition and the Diamond Wire Saw for Granite — JOY-WS-G for granite block cutting.
Before ordering, confirm the dominant material: heavily reinforced demolition concrete behaves very differently from clean quarry granite, and a wire chosen for one will disappoint on the other. If a job mixes sections, plan the cut sequence rather than trying to compromise with a single wire. Keep water flowing at the correct volume, re-tension the wire as beads wear, and store spare coils dry so the rubber moulding does not crack. When bead wear looks uneven across the coil, the line speed or tension is usually the cause — worth discussing with the supplier before the next order.
