FAQs

What types of materials can the blades cut?

The set includes blades suitable for cutting wood, wood with nails, and general fast cutting applications. The flush cut blade is also useful for precise trimming in wood.

What grit sandpapers are included?

The set includes detail sanding sheets in 60 grit (for coarse removal), 80 grit (for medium sanding), and 120 grit (for finer finishing).

Are these accessories compatible with all oscillating multi-tools?

These accessories are designed for oscillating multi-tools. While DeWalt tools offer broad compatibility, always check your specific tool's manual to ensure it accepts this type of accessory attachment.

How should I store the accessories?

All accessories should be stored in the provided durable plastic carry case. This keeps them organized, protected, and easy to transport.

How do I attach a blade or sanding plate?

Refer to your oscillating multi-tool's user manual for the specific attachment procedure. Generally, it involves loosening a screw or lever, fitting the accessory, and then tightening it securely.

Can I use these for metal cutting?

This specific set is primarily designed for wood and general materials. It does not contain blades specifically intended or optimized for cutting metal. For metal cutting, specialized metal cutting blades are recommended.

How long do the blades typically last?

Blade lifespan varies greatly depending on the material being cut, the cutting technique, and the duration of use. Blades will eventually become dull or damaged and will need to be replaced.

Troubleshooting

Accessory not attaching securely to the tool.

Ensure the correct accessory type is being used and that it is properly aligned with the tool's mounting system. Check for any debris obstructing the connection point and ensure any locking mechanisms (screws, levers) are fully engaged.

Blades are not cutting efficiently.

Check if the blade is dull or damaged. For specific materials, ensure you are using the correct blade type (e.g., wood blade for wood, flush cut blade for precise trimming). The performance of the blade is also dependent on the speed and power settings of your oscillating tool.

Sanding sheets are wearing out too quickly.

Ensure you are using the appropriate grit for the material and task. Avoid excessive pressure, which can wear down the abrasive faster. Clean off dust buildup from the sheet periodically if possible.

Carry case latches are difficult to open/close.

Ensure the case is clean and free of debris. If they feel stiff, a small amount of lubricant might help, but avoid over-application. If damage is suspected, contact the manufacturer.

Setup, Compatibility & Care

Compatibility:

This DeWalt accessory set is designed for use with oscillating multi-tools. Ensure your tool has a compatible blade attachment system. DeWalt oscillating tools typically offer broad compatibility with their own accessory range.

Setup:

  1. Ensure your oscillating multi-tool is switched off and unplugged from the power source.
  2. Select the appropriate blade or sanding plate from the case.
  3. Attach the accessory to the tool's head following your tool's specific instructions. This usually involves loosening a screw or lever, fitting the accessory, and then tightening it securely.
  4. Once attached, plug in and switch on your tool to begin use.

Care:

  • Cleaning: After use, clean blades and sanding plates to remove debris. Use a dry cloth for general cleaning. For stubborn residue, a slightly damp cloth can be used, but ensure all parts are thoroughly dried before storage.
  • Storage: Store all accessories in the provided plastic carry case to prevent damage and loss. Keep the case in a dry environment.
  • Inspection: Regularly inspect blades for wear, damage, or dullness. Replace worn sanding sheets as needed to maintain performance.
