Circular Saw Blade DeWALT DT20460-QZ for Multiple Materials

The Circular Saw Blade DeWALT DT20460-QZ for Multiple Materials is a 300 mm segmented diamond blade engineered for masonry and mixed-material cutting tasks. Designed by DeWalt for professional and DIY use, the blade combines a segmented Turbo Design and a high-strength steel core with integrated cooling vents to deliver aggressive, fast cutting while resisting heat-related distortion. With a 12 mm segment height and optimized diamond matrix, this blade provides extended cutting life and consistent performance across concrete, slabs, brick, and block work.

Advantages

The segmented construction and Turbo Design enable efficient material removal and rapid cutting progress. A 12 mm segment height maintains sharpness over prolonged use and helps reduce the frequency of blade changes. Integrated cooling vents in the steel core dissipate heat and minimize distortion, supporting durability under continuous operation. Overall, the blade delivers up to three times longer life in masonry cutting applications compared to standard HP range concrete blades, making it a reliable choice for heavy-duty jobs.

Suitable for

• Cutting concrete and reinforced concrete
• Slab and pavement cutting
• Brick and block cutting
• General masonry and construction site cutting tasks

Key specifications

• Blade diameter: 300 mm
• Segment type: Segmented Turbo Design for aggressive cutting
• Segment height: 12 mm
• Core material: High-strength steel with integrated cooling vents
• Application: Masonry materials including concrete, slabs, brick, and block
• Performance: Up to 3X longer life in masonry cutting compared to HP range cutting C35 concrete

How to use

Install the DeWALT DT20460-QZ on a compatible 300 mm circular saw or cut-off machine following the tool manufacturer's mounting and safety instructions. Ensure the blade rotation matches the saw's rotation direction and that the blade is securely tightened. Use appropriate feed rate—do not force the blade—allowing the segmented Turbo Design to clear debris and cool between passes. Wear suitable personal protective equipment, and if cutting dry, monitor blade temperature; where possible use wet cutting or intermittent cutting to further manage heat and dust.

Usage recommendations

For best results on masonry, use the blade with bladespeed and feed consistent with the saw's rating, maintain steady pressure, and allow the integrated cooling vents to dissipate heat. Replace the blade when segment wear reduces cutting efficiency or when visible damage appears. Follow site safety regulations and dust control measures during operation.
