DEWALT DT4321-QZ 165mm 24T cirkelzaagblad, HM, ATB, 20mm boring, Extreme Runtime

This DEWALT DT4321-QZ circular saw blade delivers fast, efficient cuts in wood with its 165 mm diameter and 24-tooth configuration. The tungsten carbide tipped (TCT) teeth with alternate top bevel (ATB) geometry and 10° hook angle ensure clean, aggressive cutting performance, while the anti-friction coating reduces heat and pitch build-up. Optimized for cordless circular saws, the blade features anti-kickback design and expansion slots for reduced noise and vibration, maximizing runtime and user comfort.

Advantages

The Extreme Runtime series is engineered to extend battery life in cordless tools. The thin kerf (1.65 mm) and low-friction coating minimize drag, allowing the saw to cut faster and longer per charge. The anti-kickback shoulder behind each tooth limits feed rate for safer operation, and the expansion slots dissipate heat and noise, improving cut quality and blade longevity.

Suitable for

• General purpose wood cutting, including softwood, hardwood, and construction lumber
• Crosscuts and rip cuts in solid wood and sheet goods
