The Shark Series Diamond Blades are 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. Join the many customers who keep coming back to get more Shark Blades, available only at Sencore Diamond Tools.
