Founded in 1998 in the coastal city of Split, Dalmatian Drilling Tools Ltd. has grown from a small local workshop to one of Croatia's most respected manufacturers of thread button bits. What started with a handful of craftsmen repairing drill bits for local quarries has evolved into a state-of-the-art facility producing over 50,000 bits annually, exported to 30+ countries.
At the core of Dalmatian's product line is its thread button bits, available in diameters ranging from 38mm to 152mm, suitable for everything from small-scale construction to large mining operations. The company prides itself on its proprietary button design—using high-grade tungsten carbide (YG11 and YG13 grades) for superior wear resistance, and a unique heat treatment process that ensures the buttons stay fused to the steel body even under extreme impact. Their taper button bits, in particular, have gained a following in the Middle East, where they're used in hard rock mining for their ability to penetrate granite and basalt with minimal vibration.

In addition to thread button bits, Dalmatian also produces diamond core bits for geological exploration, with a focus on impregnated and surface-set designs for accurate sampling in soft to medium-hard formations.
What truly sets Dalmatian apart, though, is its customer-centric approach. The company offers custom bit designs, working closely with clients to tailor button arrangement, shank type, and thread specifications to specific drilling conditions. Their wholesale program, which includes bulk pricing for orders over 100 units, has made them a favorite among distributors in the EU and Balkans. "We don't just sell bits—we solve drilling problems," says CEO Ivan Petrovic. "Whether a client is struggling with bit life in abrasive rock or needs a faster penetration rate, we engineer a solution."
Recent investments in 3D printing technology have allowed Dalmatian to prototype new bit designs in days rather than weeks, accelerating innovation. For example, their new "SpiralFlow" thread button bit features a helical water channel that improves debris flushing, reducing bit clogging in clay-rich formations. This attention to detail has solidified their reputation as a forward-thinking manufacturer in the rock drilling tool industry.
Located in Croatia's capital, Zagreb RockBit Industries has made a name for itself as a leader in tungsten carbide button bits since its founding in 2005.
