A TCT circular saw blade (Tungsten Carbide Tipped Saw Blade) is manufactured by brazing carbide tips onto a high-strength alloy steel body. Compared with conventional HSS blades, TCT blades offer:
Higher hardness
Better wear resistance
Longer service life
They are widely used for cutting steel, stainless steel, non-ferrous metals, plastics, and composite materials, especially in continuous production environments.

What is a cold saw blades, and what are its characteristics?
During the cutting process with a circular saw machine, the heat generated by the saw blade teeth cutting the work piece is transferred to the chips through the teeth, while the work piece and the saw blade remain cool-hence the name "cold saw," which refers to what we call a cold saw blade.

Characteristics of Cold Saw Blades
Improved Stability in Cutting Accuracy
Based on actual usage, significant resources have been devoted to developing specialized technologies to optimize the blade body of cold saw blades. This continuously enhances the stability of cutting accuracy during work piece cutting and provides exceptional resistance to the reduction in blade rigidity caused by heat generated from friction during the cutting process.
Effective Reduction of Tooth Vibration to Prevent Diagonal Cutting
Through collaborative R&D with advanced saw blade manufacturers from multiple countries, a unique side profile for cold saw blades has been designed. This effectively reduces vibration during cutting, controls the root cause of diagonal cutting, and minimizes adverse effects on the saw blade.
Extended Service Life
By categorizing different materials and circular saw machines, a diversified selection of cold circular saw blades (e.g., for ironworking) is achieved. This ensures a longer cutting lifespan while also improving the quality of the cut work pieces
Breaking Speed Limits for Higher-Speed Cutting Operations
The use of specially treated teeth (commonly known as "tips") allows for flexible adjustment of the cutting volume per tooth (increased), enabling faster operation compared to commonly used high-speed steel saw blades on the market-thereby improving cutting efficiency.
