Frequently Asked Questions (FAQ)

Q1: What distinguishes your diamond blade for cutting granite from general-purpose diamond blades?

A1: Our blades are specifically engineered for the unique characteristics of granite. This includes a tailored diamond grit size, a harder metal bond matrix that slowly wears to expose fresh diamonds, and often a higher diamond concentration. General-purpose blades may cut granite, but will do so slower, with more wear, higher heat, and a poorer finish, drastically reducing efficiency and blade life.

Q2: Is wet cutting or dry cutting recommended for granite with your blades?

A2: For optimal performance, extended blade life, and dust control, wet cutting is strongly recommended when using our granite blade. Water acts as a coolant, preventing overheating of the segments and core, and effectively flushes away cutting debris, allowing the diamonds to cut more efficiently. While some of our blades are designed for short dry cuts, sustained dry cutting on granite will significantly reduce blade life and may void warranty.

Q3: How do I select the correct bond hardness for my granite cutting application?

A3: The general rule is: for harder, more abrasive granite, use a softer bond. This allows the bond to wear away at an appropriate rate, consistently exposing new, sharp diamonds. For softer, less abrasive granite, a harder bond is used to prevent the diamonds from being released too quickly. Our technical sales team can assist in selecting the ideal bond for your specific granite type.

Q4: What maintenance is required for your diamond blades?

A4: Regular inspection for segment damage or core warping is essential. Ensure proper machine alignment and secure mounting to prevent uneven wear. Periodic dressing of the blade with an abrasive stone can help expose fresh diamonds if the blade starts to glaze or cut slowly. Always store blades in a dry, protected environment.
