Which Protection Level is Right for You?
Drill Defender Core: The Smart Choice for Everyday Drilling
Core sonde housings are built from higher-grade steel than the industry standard, and are through-hardened for additional strength and durability. These housings are tougher than comparable entry-level options to keep you drilling longer.
For crews drilling primarily in dirt and non-abrasive conditions, Core housings deliver dependable performance without the cost of enhanced wear protection that may not be required for the job.
Drill Defender Edge: The Balanced Option for Cost and Durability
Edge sonde housings feature targeted laser cladding to the areas most susceptible to wear, delivering added protection where it matters most without unnecessary buildup. This balanced design helps extend housing life, reduce replacement frequency, and improve overall tooling value.
For drillers working in mixed ground conditions, Edge provides enhanced durability and wear resistance so crews can keep drilling with less concern over premature tooling changes.
Drill Defender Apex: The Best Choice for Superior Wear Protection
Apex sonde housings offer the highest level of wear protection on the market. Featuring the same extensive laser cladding that has made Drill DefenderTM a trusted name in HDD since 2019, Apex is designed to maximize housing life in the harshest drilling environments.
For contractors who prioritize maximum product life, long-term tooling value, and the fewest tooling changes, Apex delivers extreme durability for demanding everyday jobs and the toughest ground conditions.
