Frequently Asked Questions
Q: What size of blades does the Dewalt DWS778 accept?
A: This mitre saw takes 250mm diameter blades with a 30mm bore. When selecting replacement or specialty blades, make sure they match those sizing specifications for safe and accurate use.
Q: Can it be used with standard home power sockets?
A: This model operates on a 110V power supply, which is often used on UK building sites for safety. It is not compatible with typical 230V residential sockets without the correct transformer, so check your power setup before purchase.
Q: Does it support both left and right mitre angles?
A: Yes, the saw mitres up to 50° in both directions, letting you create precise angled cuts to the left and right. The positive stops at common angles help speed up repetitive tasks and boost accuracy.
Q: How effective is the dust extraction, and do I need a vacuum attachment?
A: The integrated dust extraction system helps capture a significant amount of sawdust generated during cutting, improving visibility and reducing cleanup. For best results, you can connect it to a compatible shop vacuum or dust extractor.
Q: Is it easy to transport between job sites?
A: While weighing 17.2kg, the saw is engineered with portability in mind, featuring a compact rail system that reduces its footprint. For frequent transport, consider using a carry case or wheeled stand if you need to move it often.
Q: What accessories come included in the box?
A: The saw comes with a 250mm TCT blade, a clamp for securing work pieces, and a hex key for blade changes and adjustments. Additional clamps or specialty blades may be purchased separately for specific materials or needs.
