DEWALT EXTREME Impact Spade Bit 22mm x 406mm DEWDT4786-QZ

Description

High-Speed Drilling Performance for Demanding Trade Work

The DEWALT EXTREME Impact Spade Bit 22mm x 406mm DEWDT4786-QZ is built for electricians and contractors who need fast, consistent drilling on site without slowing down. The precision-ground central point helps the bit bite quickly into timber, improving drilling speed and reducing walking at the start of the cut.

Chamfered outer edges deliver cleaner hole finishes while maintaining high drilling efficiency across hardwood, softwood, and general construction lumber. Whether you’re running cables through framing or working through mixed material conditions, this spade bit is designed to keep productivity high on busy jobs.

Built for Durability, Reliability, and Tough Site Conditions

When reliability matters, this DEWALT EXTREME spade bit is engineered to handle real-world trade use. The extra thick, robust steel shank enhances durability under load, helping reduce wear during repetitive drilling tasks on residential, commercial, or maintenance projects.

The design also supports drilling through timber with embedded nails, helping minimise interruptions when unexpected materials are encountered. With a strong 1/4″ shank connection, it ensures a secure, slip-resistant fit in compatible drivers, helping maintain control and consistency across high-torque applications.

This is a dependable choice for licensed electricians and contractors who need tools that perform consistently across multiple jobs without premature failure.

Trade Efficiency and Jobsite Convenience

The extended 406mm length gives you the reach needed for deeper or awkward access drilling, reducing the need for multiple setups or tool changes. This helps streamline installation work, especially when running services through wall frames or tight construction spaces.

Designed for compatibility with standard quick-change 1/4″ chucks, it integrates easily into existing trade toolkits, saving time on bit swaps and keeping workflows efficient. Ideal for fast-paced electrical rough-ins and maintenance tasks where downtime directly impacts project schedules.
