That's where our impregnated core bits excel."

Island GeoTools' impregnated core bits are engineered with a matrix that bonds diamond particles tightly, ensuring consistent cutting even in the hardest volcanic rock. They offer custom sizes, from small 36mm bits for micro-sampling to large 150mm bits for deep geological drilling. The company also produces surface set core bits, but these are optimized for research rather than construction—their surface-set diamonds are arranged in a pattern that minimizes vibration, reducing the risk of sample breakage. "We once worked with a team from the University of Paris studying hydrothermal vents off the coast of Mohéli," Dr. Ali recalls. "Their core samples needed to be intact to analyze microbial life, so we designed a specialized surface set core bit with a reinforced outer shell. The results were groundbreaking."

While Island GeoTools primarily serves academic institutions and government research agencies, they also partner with international mining companies conducting pre-exploration surveys. Their small but dedicated team prides itself on collaboration, often working directly with clients to modify bits for unique geological challenges. "Comoros' geology is diverse—one area might have soft coral reef deposits, another hard basalt," Dr. Ali explains. "We don't believe in a one-size-fits-all approach. Every project gets a tailored solution."

Their most popular offering is a 76mm carbide core bit designed for medium-hard rock, which has become a staple for local drillers. For areas with harder formations, such as the volcanic highlands of Grande Comore, they offer impregnated core bits with a higher diamond concentration. "We recently worked with a community in Mitsamiouli to drill a well that hit bedrock at 50 meters," Ousseni says. "Our impregnated core bit cut through that rock like butter, and the well now serves over 300 families. That's the impact we strive for."

What makes Comoro WellTech unique is its focus on affordability and accessibility. They offer flexible payment plans for small-scale drillers and run training workshops on bit maintenance to help extend tool life. "Many local drillers can't afford to ｒｅｐｌａｃｅ bits frequently, so we teach them how to sharpen carbide edges and clean matrix pores in impregnated bits," Ousseni explains. "A well-maintained bit can last twice as long, which saves them money and keeps projects on track." The company also partners with NGOs and government water programs, providing discounted rates for community projects.
