Bond hardness matching is the primary factor controlling diamond blade cutting speed and service life.
Diamond blade performance depends as much on metal bond hardness as on diamond grit size. Protec Tools engineers bond formulations so soft abrasive materials wear the bond fast enough to expose fresh diamonds, while hard materials use harder bonds to prevent premature undercutting.
Bond Matching Rules
- Soft bond for hard materials like granite and hard concrete.
- Hard bond for abrasive materials like asphalt and green concrete.
- Medium bond for mixed masonry and general construction cutting.
Field Diagnosis
- Glazing means bond is too hard for the material being cut.
- Fast segment wear means bond is too soft for abrasive aggregates.
- Adjust blade specification rather than forcing feed rate.
