Introduction: The Cost of Choosing the Wrong Blade
In the construction and stone fabrication industry, diamond saw blades are the most essential cutting tools. They are widely used for cutting hard, brittle materials such as concrete, refractory materials, stone, and ceramics. A diamond blade consists of two parts: the core (the steel body that provides support) and the segments (the cutting edge containing diamond crystals).

This article systematically explains the four key dimensions of diamond blade selection: Blade Type, Bond Selection, Cutting Method (Wet vs. Dry), and Grit Size-helping you get it right the first time.
Three Types of Diamond Saw Blades Explained
Diamond blades are primarily classified into three types based on rim design: Segmented Blades, Continuous Rim Blades, and Turbo Blades. Each type has its own strengths, weaknesses, and ideal applications.
1.Segmented Blade – The Speed Champion
Segmented blades feature individual diamond segments separated by gaps (called "gullets" or "expansion slots").
Advantages: Fastest cutting speed. The gaps allow efficient debris removal, preventing the blade from binding. They also aid heat dissipation, making them ideal for dry cutting.
Best For: Heavy materials like concrete, asphalt, and brick; demolition work, road cutting, and other high-intensity applications.
Limitations: Rougher cut quality with possible minor chipping. Not recommended when surface finish quality is a priority.
2. Continuous Rim Blade – The Precision Specialist
Continuous rim blades have a solid, uninterrupted diamond rim with no gaps.
Advantages: Smoothest, cleanest cut with zero chipping. Delivers chip-free precision cutting without impact or vibration.
Best For: Tile, porcelain, granite, natural stone, and other materials requiring a premium edge finish. Typically requires wet cutting to maintain low temperatures.
Limitations: Slowest cutting speed. Not suitable for heavy concrete cutting.
3. Turbo Blade – The All-Rounder
Turbo blades combine features of both segmented and continuous rim blades-featuring a wavy or serrated rim design.
Advantages: The best balance of speed and finish. Cutting speed is approximately 70% of segmented blades, while surface quality is about 80% of continuous rim blades. Can be used for both dry and wet cutting.
Best For: Mixed materials, concrete pavers, granite, hard stone, and general-purpose applications.
Limitations: Typically priced higher than segmented blades.
