Our premium aluminum cutting saw blades (non ferrous) have been specifically designed with a negative hook angle, triple chip tooth grind, and precision ground micro grain carbide tips for clean cutting. The specially formulated tungsten carbide in these aluminum cutting saw blades lasts longer than other carbide grades and leaves burr free cuts in all types of non ferrous metals, such as: aluminum, copper, brass, bronze, and even most plastics. The 10” and larger metal cutting saw blades feature copper plugged expansion slots for reduced noise and vibration while several of the smaller diameter blades feature laser cut expansion slots and heat vents for cooler operation in cutting. These durable high grade aluminum and non ferrous metal cutting saw blades provide excellent smooth cuts and outlast many other competitive blades.
