DEWALT EXTREME Tri Flute Drill Bit 22mm x 152mm DEWDT90242-QZ

Description

High-Speed Drilling Performance That Saves Time on Site

The DEWALT EXTREME Tri Flute Drill Bit 22mm x 152mm (DEWDT90242-QZ) is built for electricians and contractors who need fast, accurate wood drilling without slowing down the job. Its three cutting edges deliver up to 6x faster cutting performance compared to traditional flat bits, helping you complete rough-in and installation work more efficiently.

The tri-flute design improves chip removal, reducing clogging and binding when drilling deeper holes up to 100mm. This means smoother operation, less effort on the drill, and more consistent results across repetitive site tasks like framing, cable runs, and fixture installations.

Built for Reliability, Cleaner Holes, and Long Tool Life

On busy construction sites, reliability matters. This DEWALT drill bit is engineered with three cutting spurs that produce cleaner entry and exit holes, reducing splintering in timber and improving overall finish quality.

The full screw tip allows the bit to self-feed into timber, giving you better control and reducing the need for excessive pressure. This not only improves safety but also extends bit life by minimizing wear during repeated use.

Designed for professional-grade durability, this bit is made to withstand frequent use across residential, commercial, and maintenance projects where consistent performance is critical.

Trade-Ready Design for Faster Setup and Compatibility

Time saved on setup is time earned on site. The quick-change 6.35mm hex shank allows fast bit swaps and fits standard quick-change extensions and 1/4″ adapters, helping you move between tasks without delays.

This makes it especially useful for electricians working across multiple fixings, penetrations, and timber structures in a single day. Whether you’re on new builds or retrofit work, the design helps reduce downtime and keeps workflows moving efficiently.

With DEWALT’s EXTREME engineering, this bit is made to support professional trades who need dependable tools that integrate seamlessly into their existing kit.
