Their warehouse in Majuro is stacked with cases of electroplated core bits (used for geological sampling) and impregnated diamond core bits (perfect for hard rock exploration).
Geologists working on environmental surveys rave about their NQ and HQ impregnated diamond core bits. These bits use a matrix of diamond particles embedded in the cutting surface, allowing them to grind through granite and basalt while capturing intact core samples. For road crews, their road milling cutting tools are a must—specifically the tungsten carbide tips that fit Wirtgen milling machines, a common sight on Marshallese road repair projects.
Why Choose Them?
Their wholesale prices are unbeatable—order 50+ core bits, and you'll get 15% off. They also offer free shipping to any major island (Majuro, Ebeye, Kwajalein), and their online ordering system makes it easy to track inventory levels. For last-minute orders, they even have a "rush delivery" option (for a fee) using local cargo boats.
Marine drilling in the Marshall Islands comes with unique challenges—saltwater corrosion, shifting seabeds, and the need for waterproof equipment. Atoll Drilling Innovations has made it their mission to solve these problems with specialized tools designed for coastal and offshore projects. From oil rig components to underwater core sampling equipment, they've got the gear to get the job done in harsh marine environments.
Their star product? Oil PDC bits, which are engineered to withstand the high pressures and temperatures of offshore oil exploration. These bits feature a steel body with diamond compact cutters that maintain sharpness even when drilling through sandstone and shale.
