Diamond Segmented Blade DeWalt DT20465-QZ 350 mm — for Reinforcing Bars and Concrete

Diamond segmented blade DeWalt DT20465-QZ, 350 mm diameter, is designed for cutting reinforced bars and concrete on construction sites and in workshops. The segmented rim ensures effective debris removal and improved cooling during intensive cutting, enabling stable performance in demanding applications. The blade is compatible with angle grinders and cut-off machines that accept a 350 mm cutting disc, providing a practical solution for professional concrete and rebar cutting tasks.

Advantages

The segmented diamond rim offers fast cutting rates and enhanced chip clearance, which reduces clogging and maintains cutting speed when working with reinforced concrete. Optimized cooling characteristics extend blade life under heavy use and help preserve cutting precision. The blade’s robust construction provides consistent results across repeated cuts, while its compatibility with standard 350 mm machines simplifies tool selection on site.

Suitable for

• Cutting reinforced concrete and concrete slabs
• Slicing through reinforcing bars (rebar)
• Use with compatible angle grinders and cut-off machines
• Jobsite and workshop concrete cutting operations

Key specifications

• Diameter: 350 mm
• Blade type: Segmented diamond rim
• Material compatibility: Reinforced concrete, concrete with rebar
• Typical applications: Wet and dry cutting on construction sites (follow machine capability)
• Designed for professional use with high removal rate and improved cooling

How to use

Mount the blade on an appropriate 350 mm angle grinder or cut-off machine according to the machine manufacturer’s instructions and ensure the blade is fitted in the correct rotation direction. Verify that the machine’s maximum speed matches the blade’s rated speed before operation. Use appropriate feed pressure—steady and controlled—to allow the diamond segments to work efficiently and avoid forcing the blade. Maintain a secure work setup and steady cutting line to achieve straight cuts through concrete and rebar.

Usage recommendations

Always wear appropriate personal protective equipment including eye, ear and respiratory protection, and gloves. Inspect the blade before use for visible damage or excessive wear. For prolonged cutting, allow brief pauses to improve cooling and consider using wet cutting where compatible with the machine and site conditions. Follow manufacturer guidelines for safe operation and regular maintenance of both blade and machine.
