The Makita 6-1/2 in. 25T Carbide-Tipped Max Efficiency Ultra-Thin Kerf Circular Saw Blade is engineered for use with cordless circular saws and is ideal for a full range of wood cutting applications. The ultra-thin kerf design (only 0.055 in.) and specially engineered blade teeth assist in reducing the load put on the tool while cutting. In addition， the reduced swing width allows for smoother material removal with less cutting resistance. The result is increased cutting efficiency and up to 25% more cuts per charge compared to standard blades. The high grade Tungsten Carbide tips are engineered for improved durability and longer blade life， and the special ATAFR (Alternate Top Alternate Face with Raker) carbide tips provide smoother and faster cuts. This saw blade is for use with 6-1/2 inch Cordless Circular Saws with 5/8 inch arbor (models XSS01Z and XSH03M， sold separately).
