This Dozuki Dovetail saw with Rip/Crosscut Teeth is designed for fast, accurate cuts. Since the rigid spline is not full length of the blade, it can easily make long, accurate cuts in thin material. The blade is only 0.012" thick and the teeth are impulse hardened for extended wear. The blade length is 9 1/2" and overall length is 21" and can easily be replaced if damaged. Replacement Blade #155685 or 155659.
