The Tuna Series Diamond Blades are another of our signatures trademark. We here at Sencore wanted to, not only sell, provide the BEST Diamond Blades possible. Our crafty and smart team spend time developing a better and cooler blade without overheating like the rest in the market. We increased the diamond concentration and gave it an amazing segment height of 13mm, which is one of the industries highest, and added our trademark of 6 Over-Sized Cooling Holes to give the blade a better cooling capacity.
