DEWALT EXTREME SDS-plus Concrete Drill Bit 22mm x 450mm x 400mm 4 Cutter DEWDT9687-QZ

Description

High-Performance Drilling Power for Demanding Concrete Jobs

When you’re drilling into reinforced concrete on tight project schedules, you need a bit that keeps up without slowing you down. The DEWALT EXTREME SDS-plus Concrete Drill Bit 22mm x 450mm x 400mm (DEWDT9687-QZ) is built for serious trade use, delivering consistent drilling performance even in heavily reinforced substrates.

Designed as part of the Elite Series, this 4-cutter carbide head setup gives you faster penetration and smoother cutting action through concrete. Whether you’re setting anchors, running services, or working through dense slabs, this bit is engineered to maintain speed while reducing strain on your drill. The high-speed blasting process strengthens the body to help reduce breakage risk, especially during heavy-duty drilling applications.

With its 2-stage flute design and variable helix, debris is cleared efficiently from the hole, helping you maintain drilling speed and reduce downtime on site.

Built for Rebar Impact, Wear Resistance & Long-Term Reliability

On commercial and industrial sites, hitting rebar is unavoidable—but downtime from broken drill bits is not an option. This DEWALT EXTREME SDS-plus concrete drill bit is engineered with rebar strike resistance, helping it withstand contact with reinforcement steel while maintaining structural integrity.

The 4-cutter carbide head increases carbide surface area for improved wear resistance and extended service life—offering up to 2x life compared to previous designs. That means fewer bit changes, fewer interruptions, and better productivity across multiple drilling tasks.

A full carbide pilot feature allows for more accurate starts and stable positioning, reducing wandering on hard surfaces. Plus, the anchor wear mark indicator helps ensure correct hole sizing for anchor installation—so you know exactly when the bit is no longer within tolerance for precision fixing work.

Made in Germany, this bit is built to meet the expectations of professional electricians and contractors who need dependable performance job after job.

Trade-Ready Design for Faster, Cleaner On-Site Work

Every feature of this SDS-plus drill bit is designed with real trade workflows in mind—where speed, accuracy, and convenience directly impact project delivery.

The full carbide pilot improves hole accuracy from the first contact, reducing rework and saving time during layout and installation. Meanwhile, the advanced flute system continuously removes dust and debris, helping maintain cutting efficiency and reducing heat build-up during prolonged drilling.

For electricians and contractors working across residential, commercial, and industrial projects, this bit helps streamline anchor installation and heavy-duty concrete drilling without constant tool changes or performance loss.
