Why Do Granite Cutting Blades Have Segments?

Those gaps in your granite cutting blades aren’t random - they’re engineered cooling vents. Here’s why segmented blades dominate natural stone cutting:

The Physics of Cutting Blade

• Airflow through gaps reduces blade temperature by 35%

• Expansion spaces prevent warping during 1,500°F friction spikes

• Segmented design allows 0.5-1.5mm diamond overhang for chip clearance

• 
  

Best Practice

Choose laser-welded granite cutting blades with cobalt bonding for wet conditions. Milwaukee’s 14” segmented blade cuts 3cm granite countertops at 45 linear feet per hour with 0.035” kerf loss.
