DEWALT XLR SDS-plus Full Head Carbide Concrete Drill Bit 5mm x 160mm x 100mm 4 Cutter DEWDT8908-QZ

Description

High-Performance Concrete Drilling for Demanding Site Work

The DEWALT XLR SDS-plus Full Head Carbide Concrete Drill Bit 5mm x 160mm x 100mm 4 Cutter (DEWDT8908-QZ) is built for licensed electricians and contractors who need consistent drilling speed and clean hole formation in concrete. The full head carbide design maximises contact for efficient material removal, helping you work faster on repetitive anchoring and fixing tasks.

With a 2-stage flute design and variable helix pattern, debris is rapidly cleared from the cutting zone, reducing binding and helping maintain drilling speed even in tougher concrete applications. The full carbide pilot feature also supports quick starts and more accurate hole positioning, improving productivity on layout-critical installs.

Built for Durability, Rebar Resistance & Reduced Breakage

Designed as part of the Elite Series, this drill bit is engineered for tough jobsite conditions where concrete and rebar are unavoidable. The rebar strike resistant design helps reduce the risk of breakage when hitting reinforcement, keeping downtime and tool replacement costs to a minimum.

The high-speed blasting strengthening process improves overall bit durability, while increased carbide surface area delivers up to 2x life compared to previous designs, making it a reliable choice for high-volume drilling tasks. The anchor wear mark indicator allows installers to maintain correct hole diameter for proper anchor installation—helping ensure compliance and installation accuracy on critical fixings.

Trade-Focused Design for Faster, More Accurate Installations

Built for professional electricians and contractors working under tight project schedules, this SDS-plus drill bit supports efficient installation workflows across residential, commercial, and industrial sites.

From fast positioning with the carbide pilot tip to reduced debris clogging and wear visibility control, every feature is designed to minimise interruptions and keep crews moving. Ideal for repetitive anchoring jobs where speed, consistency, and accuracy directly impact project timelines and labour efficiency.
