Granite Saw Blades Diamond Blades Engineered for Hard, Abrasive Natural Stone

Blade life depends on three variables: granite hardness, segment height, and feed rate. As a general benchmark, a standard 400 mm blade with 12 mm segment height cutting medium-hard granite on a bridge saw delivers approximately 800–1,500 linear meters before segment exhaustion. Harder granite shortens life; softer granite extends it.

Our 15 mm segments increase total life proportionally — roughly 30–40% more linear meters for a modest cost increase. We recommend 15 mm segments for any customer running production volumes because the per-meter cutting cost drops even though the per-blade price is slightly higher.

For standard wet-cutting on bridge saws and table saws — which covers 90%+ of granite fabrication applications — high-frequency welded blades are the correct choice. They cost less, the joint strength is fully adequate for wet-cut operating conditions, and they perform identically to laser-welded in this application.

Laser welding is necessary only when the blade will face thermal cycling: dry cutting, high-RPM hand-held saws, or applications where water supply is intermittent.

Stocking HF-welded as your standard and keeping laser-welded for specific requests optimizes your inventory cost without sacrificing coverage.

A medium-bond "general purpose granite" formula handles a variety of granites at acceptable performance — not optimal on any single stone, but usable across a range. For distributors supplying small shops that cut mixed materials from different slabs daily, this is a practical SKU choice.

However, any customer running volume on a single granite type (which is most countertop fabricators — they buy slabs in bulk from one quarry) will see 25–40% better life and feed speed from a formula matched to that specific stone.

Our recommendation: stock general-purpose as your entry SKU, then transition high-volume customers to stone-matched formulas once you identify what they cut most.

Standard diameters (300–600 mm) on existing stock formulas: 50 pieces per specification. Larger diameters (700–900 mm): 30 pieces per specification due to higher per-unit value.

Private-label orders: 100 pieces per SKU to cover packaging setup. Formula development orders (new bond for a specific granite type): 50 pieces minimum for the first production run.

We offer sample quantities of 5–10 pieces for field testing before committing to production volume — priced at production rates, not inflated "sample pricing."

Bond chemistry. A general-purpose diamond blade uses a mid-range bond hardness designed to cut multiple materials acceptably. On hard granite specifically, that mid-range bond is typically too hard — the matrix doesn't erode fast enough, diamonds go dull, and the blade glazes.

Our granite-specific blades start from a soft bond baseline and adjust from there based on the specific granite's abrasiveness. The segment geometry (width, number of segments, gullet depth) is also optimized for granite's cutting characteristics rather than being a compromise across stone, concrete, and ceramic.

Yes. Our granite saw blades are produced under our MPA-certified manufacturing process, which specifically audits segment retention (the primary safety concern at operational RPM) and dimensional accuracy.

MPA certification is required for selling diamond blades in the European market through professional distribution channels. If you're importing into the EU, our MPA certification means your product is pre-qualified — no additional safety testing needed at your end.
