Overburden drilling system

Welcome to Starockdrill - Unleashing the Magic of Three-Jaw Drilling

At Starockdrill, we believe in challenging conventional practices to deliver groundbreaking solutions. After three years of relentless dedication, we have developed a remarkable drilling tool - the concentric casing system with three jaws. This game-changing innovation enables the use of cost-effective PVC casing as a substitute for traditional steel casing, addressing the cost concerns associated with water well drilling. Our solution is versatile, adapting to various formations, including soil, flowing sand, small pebbles, and highly weathered rocks.
