Multitool blades DeWalt DT20737 – oscillating saw blades compatible with various materials

Set of DeWalt DT20737 multitool blades designed for oscillating multi-tools. These replacement blades are intended for cutting, scraping and precision tasks across a range of common materials including wood, plastics, grout and suitable soft metals. The blades are supplied to fit compatible oscillating tool interfaces and offer a practical option for renovation, repair and DIY projects where controlled cuts and access in tight spaces are required.

Advantages

DeWalt multitool blades deliver consistent cutting performance and are manufactured to match common oscillating tool mounting systems. The geometry of the teeth and blade thickness are engineered for reduced vibration and improved control during fine cuts. The set provides versatility across multiple materials, enabling one tool accessory to handle cutting and scraping tasks without frequent changes. Blades are designed for straightforward replacement, promoting quick workflow during repair and renovation jobs.

Suitable for

• Precision cuts in soft and hard woods
• Trimming and shaping plastic components
• Removing grout and mortar residue
• Cutting thin sections of soft metals where appropriate
• Detail work in renovation, carpentry and DIY repairs

Key specifications

• Compatibility: oscillating multi-tools with standard universal blade clamp
• Material suitability: wood, plastics, grout, soft metals
• Blade type: multitool oscillating saw blade set for cutting and scraping
• Design features: fine-toothed geometry for precision; reduced-thickness profile for access into narrow gaps
• Finish: corrosion-resistant coating for extended service life under normal conditions

How to use

Fit the blade onto the oscillating tool following the tool manufacturer's instructions, ensuring the blade seating and clamp are fully engaged before operation. Select an appropriate speed and apply steady, controlled pressure while cutting or scraping; allow the blade to perform the work rather than forcing it. For cutting, position the blade so teeth engage the material and guide the tool along the intended line. For grout removal or scraping, use a shallow approach and short passes to avoid chipping surrounding surfaces. Replace the blade when performance declines or when edge wear affects cut quality.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Match blade selection to the material being worked on and avoid using the blades on hardened steel or materials not specified for this blade set. Keep the blades clean and store them dry to maintain cutting performance.
