BDT's product line includes a wide range of sizes, from small NQ bits for shallow exploration to large HQ bits for deep mining projects. Their matrix-body impregnated bits are particularly popular among local mining companies, thanks to their ability to handle abrasive rock formations common in Bulgaria's Rhodope Mountains.

Their R&D team focuses on reducing bit wear rates, a critical factor for projects in hard rock like granite or basalt.

Beyond core bits, GeoCore offers a full suite of exploration accessories, including core barrels, reaming shells, and core lifters. This one-stop-shop approach is a hit with small to medium-sized exploration firms that prefer sourcing all their equipment from a single supplier.

For example, if a client is drilling in a formation with alternating soft and hard layers, RockTech can adjust the diamond concentration and matrix hardness to optimize performance.

This flexibility has made them a favorite among specialized exploration teams, including those working on archaeological drilling projects or environmental site assessments. RockTech's small-batch production model allows for quick turnaround times, with most custom orders fulfilled within 2–3 weeks. While they primarily serve the Balkans (Bulgaria, Romania, Greece), they've started exporting to Western Europe, where their attention to detail and customer service have earned them a loyal following.
