Multitool blades DeWalt DT20734 compatible replacement set

Replacement multitool blades compatible with DeWalt DT20734 offer a practical set of cutting and scraping accessories for oscillating multitools. The set includes multiple blade types designed to handle wood, soft metals and plastics, enabling a range of renovation, repair and DIY operations when used with a compatible oscillating tool. Blades are intended for cutting, scraping and light demolition tasks and provided as compatible replacements for the original DeWalt design.

Advantages

These compatible replacement blades provide a cost-effective alternative to original-brand consumables while maintaining geometry and tooth patterns suitable for common materials. The variety in blade shapes and tooth configurations increases versatility for straight cuts, plunge cuts and surface removal. Blades are designed for easy attachment to standard oscillating tool interfaces and allow quick changeover between tasks.

Suitable for

• Plunge and straight cuts in softwood and plywood
• Trimming plastic components and PVC profiles
• Light removal of thin non-ferrous metals and aluminium
• Scraping adhesives, grout and sealant residues
• Small-scale renovation and repair jobs in homes and workshops

Key specifications

• Compatible with oscillating multitools using standard quick-change blade mounts
• Multiple blade shapes included: flat cutting blades, pointed/plunge blades and scraper blades
• Material: hardened high-carbon steel for cutting blades; scraper blades with a reinforced edge
• Tooth types: fine and coarse tooth patterns for different cutting rates and finishes
• Intended applications: wood, soft metals, plastics and adhesives

How to use

Fit the selected blade to a compatible oscillating multitool following the tool manufacturer’s blade-change procedure. Secure the blade in place, select an appropriate speed setting for the material and begin with light pressure to establish the cut or scrape. Use short, controlled passes for plunge cuts and reduce feed pressure when cutting metals or plastics to avoid overheating the blade. Replace blades when cutting performance declines or when the edge becomes visibly worn.

Usage recommendations

Always wear appropriate personal protective equipment such as safety glasses and gloves. Match the blade type to the material and task: use fine-tooth blades for cleaner finishes in wood and coarse-tooth blades for faster material removal. For scraping tasks use a dedicated scraper blade and apply even pressure to avoid damaging the substrate.
