Diamond Saw Blade for Granite

Choosing the correct blade requires matching its diameter to your machine's power (kW/HP) and the arbor size. An underpowered machine will struggle to drive a large blade, leading to slow cutting and motor damage. For example, a standard bridge saw is typically suited for blade segments 400mm to 600mm.

Our diamond matrix formulation is optimized for a range of machine powers. Whether you need a blade for a 15kW bridge saw or a 45kW block cutter, we have a solution. Always consult your machine's manual to confirm its power rating and recommended blade diameter range.
 

This depends on whether you prioritize blade lifespan or material savings. Taller segment height (e.g., 20mm) directly increases tool life. A thinner kerf (thickness) removes less material, enabling faster cuts and saving valuable stone. We offer multi-layer diamond segments and sandwich segments to balance these needs, providing both durability and efficiency.

For cutting high-value granite, a thin-kerf blade is ideal. For high-volume jobs where durability is key, a standard kerf with taller, customized diamond segments offers a better cost-per-cut.

For wet cutting segments, adequate water flow is critical; it cools the blade, flushes debris, and prevents dust. Ensure a steady stream of water is directed at both sides of the blade where it enters the cut. A common guideline is 10-15 liters (3-4 gallons) per minute for larger diameter blades on bridge saws.

Insufficient water can cause overheating and damage. While some small-diameter blades may be used for dry cutting, wet cutting is always recommended for granite to ensure the best performance and blade life.
 

Blade glazing occurs when the diamond particles become dull and the metal bond smears over them, causing the blade to rub instead of cut. Signs include a drop in cutting speed and a shiny segment edge. This can happen if the bond is too hard for the granite or the feed rate is too slow.

To fix a glazed blade, you need to "dress" it by making a few cuts into an abrasive material like a dressing stick. This wears away the smeared metal from the hot-pressed segments and exposes new, sharp diamond particles.

To resolve common issues, check these points:

• Chipping:Often caused by an aggressive feed rate, unstable material, or a blade with a bond that is too hard. Check if M-shape segments, known for initial sharpness, could help.
• Blade Wobble:Can result from worn machine bearings, improper flange mounting, or a damaged blade. Inspect the blade core and sandwich segments if it's a silent blade.
• Burning Marks:Indicates insufficient cooling or excessive RPM. Ensure adequate water flow and verify the machine RPM matches the blade’s operating speed.

Properly breaking in a new diamond blade is essential for performance, as it exposes the diamonds in the segments. Make several shallow cuts (3-5 passes) in an abrasive material like soft granite. Start with a slow feed rate and gradually increase it with each pass.

This controlled wear gently removes the outer layer of the metal bond on the sintered segments, ensuring diamonds are evenly exposed without causing thermal shock. This simple step prevents glazing on the first real cut.
 

Yes, re-tipping with new diamond segments is a cost-effective practice if the steel core is in good condition. The process involves professionally laser welding new segments on, restoring cutting performance.

Lead times vary. Standard, in-stock replacement segments ship within a few business days. The re-tipping service itself takes additional time. For custom orders, please contact our team for an accurate delivery estimate.
