Saw blade attachment DeWalt DT20741-QZ — multi-material, 64 mm width, 43 mm depth

DeWalt DT20741-QZ is a multifunction saw blade attachment intended for compatible oscillating and multi-tools. Designed to cut wood, concrete and plastic, this blade offers a blade width of 64 mm and a working depth of 43 mm, enabling controlled cuts in renovation, plumbing and light construction tasks. Supplied as a single attachment, it is suitable for precision cutting where a medium-wide blade and moderate cutting depth are required.

Advantages

The multi-material construction allows one blade to perform on a range of substrates, reducing the need to swap attachments frequently. A 64 mm width provides stable cutting lines and improved edge support, while the 43 mm depth lets the user reach moderate material thicknesses and make plunge cuts for trim and routing tasks. The single-piece supply simplifies inventory management and replacement.

Suitable for

• Cutting wooden boards, panels and trim
• Removing small sections of concrete or mortar
• Trimming and cutting plastic pipes and fittings
• Plunge cuts for renovation and retrofit work

Key specifications

• Application: multi-material cutting (wood, concrete, plastic)
• Blade width: 64 mm
• Working depth: 43 mm
• Supply: single attachment
• Compatibility: designed for compatible oscillating/multi-tools (check tool interface)

How to use

Attach the blade to a compatible oscillating or multi-tool following the tool manufacturer’s instructions and ensure a secure fit before operation. Select an appropriate cutting speed and apply steady pressure; allow the blade to do the work rather than forcing it. For plunge cuts, mark the cut line, start with a shallow entry and increase depth gradually up to the 43 mm working depth as required. When cutting concrete or plastic, use controlled back-and-forth movements and avoid overheating by pausing periodically.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, gloves and dust mask. Inspect the attachment before each use for wear or damage and replace when cutting performance degrades. Match the blade to the material being cut and verify compatibility with your tool’s interface for safe and effective operation.
