Can Tile Cutting Blades Be Used on Granite Stone?

Many construction workers face a problem on site: they only have tile cutting blades but need to cut granite. Can tile cutting blades be used on granite stone? The answer is: not recommended. The hardness difference between the two materials is significant, and using tile blades on granite is not only inefficient but also poses safety risks.

4 Key Differences Between Tile Blades and Granite Blades

1. Different Diamond Concentration. Tile cutting blades have lower diamond concentration because tiles are relatively soft. Granite is much harder and requires high-concentration diamond for effective cutting. Low-concentration blades wear out extremely fast on granite.

2. Different Segment Height. Granite cutting blades typically have taller segments (10-15mm) to handle greater cutting depth and longer service life. Tile blade segments are shorter (5-8mm) and will quickly wear flat on granite.

3. Different Core Thickness. Granite cutting requires stronger core support, with core thickness generally 2.0-2.5mm. Tile blades have thinner cores (1.2-1.5mm), which easily wobble and deform when cutting hard stone.

4. Different Cooling Design. Granite blades typically use continuous rim or turbo segments with water cooling. Tile blades are mostly designed for dry cutting with limited heat dissipation, and the temperature surge when cutting granite can cause segment loss.

What Happens When Using Tile Blades on Granite

If you force a tile cutting blade on granite, these problems occur: extremely slow cutting speed, less than 1cm per minute; rapid temperature rise that may produce sparks; rough and uneven cutting surface with chipping and cracking; drastically reduced blade life, possibly failing halfway; and in severe cases, segment fly-off creating safety hazards.

Recommendations for Choosing Granite Cutting Blades

For cutting granite, use dedicated granite cutting blades. Huada Jinke recommends: choose continuous rim or segmented blades with diamond concentration no less than 30%; segment height above 10mm, core thickness above 2.0mm; prioritize water cooling to reduce blade temperature; match blade diameter to equipment power. Choose products from professional manufacturers. Huada Jinke offers various granite-specific cutting blades with OEM support, stable quality, and high cutting efficiency.
