Quick Answer

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.

Key Differences

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

How to Choose the Right Wire

• Demolition concrete with rebar → concrete wire with dense, tough beads.
• Granite quarry or block splitting → granite wire with hard-bond beads.
• Marble and soft stone → soft-bond wire that self-sharpens.
• Mixed jobs → change the wire per material instead of compromising.

How to Use It Correctly

• Keep water flowing to cool beads and remove slurry.
• Run the correct line speed for the wire spec.
• Inspect beads regularly; glazing means wrong bond, fast wear means too soft.
• Store wire coiled and dry to protect the rubber moulding.

Frequently Asked Questions

Q: Can I cut concrete with a granite wire?

A:It will wear quickly and cut slowly — concrete is abrasive and the hard bond dulls against it.

Q>Can I cut granite with a concrete wire?

A:Only for short jobs. The medium bond sheds diamond too fast on granite, so the wire wears out early.

Q: How long does a wire saw last?

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.

Conclusion

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.
