The reinforced shoulder is designed for strength and durability by providing impact resistance against nail-embedded wood.

I was so impressed with how clean the cuts using this blade. I was worried when I saw some negative reviews about using it on the FlexVolt table saw. But I made the right decision buying it. To provide more clarity about the difference between the old blade cut and the new one I added some photos. This blade can run on any table saw with speed up to 7000rpm. This can be used on a table saw or circular saw that accept blade with size of 8-1/4in. The blade runs smoothly with no sound or noise. It cuts through wood like butter and the cut is super clean. The price was amazing and I am for sure buying another one and I highly recommend you buying one too. *Note: I only gave 4 stars just to see how it runs with time and because the seller didn't provide enough information about the blade like rpm, what it can be used for, returns and warranty info. ... show more

Right blade for DW table saw
Style: New
If you are using Dewalt table saw, got to use this blade for proper kerf thickness. Works great. I used another brand which was sharp but the kerf was too narrow causing problems going through the safety blade
