Carbide teeth are welded not brazed, resulting in 30% stronger tooth bond, longer life, and durability. UC2 carbide with sub-micro grain is 70% tougher than standard carbide, stays sharp longer, and offers best-in-class cut quality. Innovative heat vents and expansion slots help make straighter cuts. Reinforced shoulder provides durability. 6 tooth count blades are best for use with thickest metals, general demolition, wood, plaster, drywall, plastic and composites.
