Thin kerf blades are designed especially for cordless tools. Because they are narrow, they take out less material and cause less loading on the battery, which results in more cuts per charge. C3 grade carbide tipped teeth stay sharper longer and provide smoother cuts than steel teeth. A hardened alloy steel body is used to ensure straight, accurate cuts. Specially engineered heat vents and expansion slots prevent blade distortion and increase blade life. Made in Japan.
