DEWALT EXTREME Impact Spade Bit 40mm x 152mm DEWDT4778-QZ

Description

Fast, Clean Drilling for Demanding Trade Work

When time is tight on site, drilling speed and consistency matter. The DEWALT EXTREME Impact Spade Bit 40mm is engineered for rapid material penetration with a precision-ground central point that helps the bit bite quickly into timber, reducing wandering and improving accuracy from the first contact.

Chamfered outer edges help produce cleaner holes while also improving drilling efficiency, so you spend less time forcing the cut and more time getting through your rough-in or installation tasks. Whether you’re working through framing timber or general lumber, this bit is built to keep productivity high across repetitive drilling tasks.

For electricians and contractors managing multiple fix-outs or service upgrades, this means fewer delays, smoother workflow, and more predictable results on every hole.

Built Tough for Site Reliability and Nail-Embedded Timber

Trade environments are unpredictable, especially during renovation and retrofit work. This spade bit is built with an extra thick, robust steel shank designed to withstand demanding drilling conditions and reduce premature wear.

It’s optimised for durability in hardwood, softwood, and lumber, including timber where nails may be present—helping reduce the risk of bit damage and downtime when unexpected obstacles are encountered on site.

The reinforced 1/4″ shank ensures a secure, slip-proof fit in impact drivers and compatible chucks, giving you confidence during high-torque applications. For licensed electricians working to deadlines, this reliability helps minimise tool changes and keeps projects moving without interruption.

Trade-Ready Design for Faster Job Completion

Designed with professional trades in mind, this DEWALT EXTREME spade bit supports efficient drilling across residential, commercial, and maintenance projects. Its fast-cutting design reduces drilling time per hole, helping crews complete rough-ins and cable routing faster.

Ideal for electricians working across multiple sites, it offers dependable performance for repetitive timber drilling tasks without sacrificing hole quality. Combined with its durable construction, it’s a practical choice for contractors who need consistent results and fewer consumable replacements.

Available through a wholesale-focused supply model, it’s suited for professionals who value fast ordering, reliable stock access, and tools that keep up with demanding project schedules.
