DEWALT EXTREME Impact Spade Bit 25mm x 406mm DEWDT4788-QZ

Description

High-Speed Timber Drilling for Demanding Trade Work

The DEWALT EXTREME Impact Spade Bit 25mm x 406mm DEWDT4788-QZ is built for electricians and contractors who need fast, accurate hole drilling through timber on active job sites. Designed for efficiency, it delivers rapid penetration through softwood, hardwood, and general construction lumber—helping reduce installation time on framing, rough-ins, and cable runs.

The extended 406mm length gives trades greater reach for deep drilling applications, making it ideal for confined spaces, wall cavities, and structural timber where standard bits fall short. With DEWALT’s robust engineering, this bit helps keep productivity high and downtime low across residential and commercial electrical projects.

Built Tough for Site Reliability and Long Service Life

When working on tight deadlines, tool failure isn’t an option. This DEWALT spade bit is engineered with an extra-thick, robust steel shank to withstand heavy-duty trade use and high torque applications.

The precision-ground central point allows faster material penetration, helping electricians drill cleanly and accurately without wandering—critical when running cables through studs or joists. Chamfered outer edges improve cutting efficiency, producing cleaner holes while extending the working life of the bit.

Its 1/4″ shank ensures secure, slip-proof clamping in impact drivers and drills, reducing slippage during high-load drilling. Whether working in new builds or retrofit installations, this bit is designed to handle real-world site conditions where timber may include nails or mixed materials.

Trade Efficiency Designed for Electricians and Contractors

For busy electrical contractors, every minute saved on drilling adds up across multiple jobs. The DEWALT EXTREME spade bit is optimized for fast setup and consistent performance, making it a reliable choice for repetitive drilling tasks in framing and cable routing.

Perfect for electricians working across residential, commercial, and maintenance projects, it supports efficient rough-in work where speed and accuracy are essential. Its extended reach and aggressive cutting design reduce the need for multiple tools, helping streamline on-site workflow.

Available through a trade-focused supply network, this bit fits seamlessly into procurement workflows for contractors who prioritize availability, fast dispatch, and consistent product supply across ongoing projects.
