Product Overview
CAHARD sintered diamond wire is designed for quarry cutting and block extraction of granite and marble. The GD quarry series includes six models for different stone conditions: GD-21, GD-22 and GD-23 for granite, and GD-31, GD-32 and GD-33 for marble.
Model selection is based primarily on stone type and hardness. Matching the wire model and operating parameters to the actual quarry material helps users select a configuration suited to the cutting conditions on site.
For natural stone materials other than granite and marble, please provide the stone information and current cutting conditions for product evaluation and selection.
Choose the Right Wire by Stone Type & Hardness
Start with the stone category, then select the model according to whether the material is hard, medium-hard or soft.
Granite Cutting Series
| GD-21 |
Hard Granite For hard granite quarry cutting and block extraction. |
| GD-22 |
Medium-hard Granite For medium-hard granite quarry cutting conditions. |
| GD-23 |
Soft Granite For soft granite quarry cutting conditions. |
Marble Cutting Series
| GD-31 |
Hard Marble For hard marble quarry cutting and block extraction. |
| GD-32 |
Medium-hard Marble For medium-hard marble quarry cutting conditions. |
| GD-33 |
Soft Marble For soft marble quarry cutting conditions. |
If the exact stone hardness is uncertain, provide the stone type, stone name or origin, quarry location and available cutting data. CAHARD can assist with model selection according to the actual material.

Actual cutting rate and wire life may vary according to stone composition, abrasiveness, quarry conditions, machine configuration, cooling and operating parameters.
Quarry Applications & Key Selection Factors
Typical Quarry Applications
- Granite quarry cutting
- Marble quarry cutting
- Granite and marble block extraction
- Large quarry block separation and primary cutting
Key Factors for Wire Selection
Granite and marble can vary significantly in hardness, mineral composition and abrasiveness. These differences affect cutting resistance and actual wire performance.
- Stone type and hardness
- Mineral composition and abrasiveness
- Current wire specification and performance, if available
- Block size and cutting dimensions
- Wire saw machine configuration
- Cooling and water conditions
The performance figures above are specified for granite and marble. For other natural stone types, contact CAHARD for evaluation rather than applying the granite or marble performance data directly.
