Includes 60T Fast Cut Wood Blade and 80T Clean Cut Aluminium Blade. Blades are fashioned from high-grade, laser cut steel. PTFE coating keeps the blades cool during use and also prevents sticking for a quicker cut and protects against corrosion and the accumulation of resin. Laser cut vibration slots, filled with polyurethane, reduce vibration and increase the accuracy of the blade by isolating the teeth and acting as a shock absorber.
