Cutting Disc DeWalt DT20590 76 x 9.5 mm — multimaterial cutting wheel

DeWalt DT20590 is a 76 x 9.5 mm multimaterial cutting disc designed for precision trimming and controlled cutting across a variety of materials. The thin 9.5 mm kerf delivers reduced material removal and accurate edge control, making the wheel suitable for handheld cutters and small machines used in repair, renovation and light workshop tasks.

Advantages

The DeWalt multimaterial cutting wheel combines a compact 76 mm diameter with a narrow 9.5 mm kerf to enable precise cuts with minimal material waste. Its construction is balanced for stability during high-speed rotation, reducing vibration and improving operator control. The disc is suitable for multiple substrates so you can use the same wheel for metal, plastic and composite trimming without frequent disc changes.

Suitable for

• Trimming metal components and sheet edging
• Cutting and shaping plastic parts
• Working with composite panels and fiberglass
• Repair and renovation tasks in workshops and on-site
• Precision cuts with handheld cutters and small bench machines

Key specifications

• Diameter: 76 mm
• Kerf (thickness): 9.5 mm
• Material compatibility: metal, plastic, composites
• Intended machine types: handheld cutters and small cutting machines
• Typical applications: trimming, edge finishing, small cuts

How to use

Fit the 76 mm cutting disc to a compatible handheld cutter or small machine following the tool manufacturer’s mounting and safety instructions. Ensure the disc is securely tightened and that the rotating direction matches the tool markings. Use steady, controlled feed rates appropriate to the material: slower feeds for thicker metal and controlled passes for plastics and composites. Always wear suitable personal protective equipment and keep bystanders clear of the work area.

Usage recommendations

For best results, match disc speed and feed to the material type: moderate RPM for metals, lower speeds and gentle pressure for plastics and composites to avoid melting or delamination. Inspect the disc before each use for damage or wear and replace it if cracking, severe wear, or imbalance is detected.
