The Dewalt trim saw blades have heavy duty carbide tips engineered to maintain a cutting edge for longer. The thin kerf blade design yields more cuts per charge by minimising battery drain and the triple action sharpening process grinds the tip to a razor sharp edge providing a smooth finish. The DT1948-QZ blades are specialised for cutting wood fast and the thin kerf design blade is perfect for use with corded or cordless plunge saws. Replaces DT1948-QZ
