Alpine's product line isn't limited to matrix body bits, though. They also produce a range of diamond core bits for softer formations, including surface set and impregnated options. What truly sets Alpine apart is its commitment to customization. Clients can request bits tailored to specific diameters (from 36mm to 200mm), thread types (R32, T38, T45), and cutting structures. "A client in Austria needed a 113mm PDC core bit for a marble quarry—we adjusted the diamond concentration and cutter angle to reduce heat buildup, and they reported a 25% increase in drilling speed," Keller adds. With a global distribution network and a 24/7 technical support team, Alpine Drilling Tools AG is more than a supplier; it's a partner in project success.
Nestled in Zurich's industrial district, SwissCore Bits Ltd has been a pioneer in impregnated core bits since 2001. Impregnated core bits, where diamond particles are evenly distributed throughout the cutting matrix, are ideal for fine-grained, hard rock—think metamorphic rocks like gneiss or schist. SwissCore's impregnated core bits are renowned for their precision, with tolerances as tight as ±0.1mm, ensuring clean, intact core samples for geological analysis. "We work closely with universities in Zurich and Lausanne to develop new impregnation techniques," explains Sophie Müller, the company's R&D manager. "Our latest innovation, the 'GeoPro' series, uses a gradient diamond concentration—higher at the cutting edge, lower in the matrix—to balance speed and durability."
SwissCore's product range covers all standard core bit sizes, including NQ (47.6mm), HQ (63.5mm), and PQ (85mm), making them a favorite among geological survey companies. They also offer custom sizes for specialized projects, such as 2 7/8-inch bits for narrow boreholes in urban exploration. Beyond impregnated bits, the company wholesales a variety of core drilling accessories, from reaming shells to core lifters, ensuring clients can source everything they need from a single supplier. "We pride ourselves on our lead times," Müller notes. "Most standard bits ship within 48 hours, and custom orders are typically delivered in under two weeks." With a focus on sustainability, SwissCore also recycles scrap PDC cutters, reducing waste and lowering costs for clients.
With roots dating back to 1988, Helvetic Mining Technologies in Lausanne is a veteran in the drilling tool industry. Specializing in surface set core bits and carbide core bits, the company has built a loyal customer base in the mining, construction, and oil & gas sectors. Surface set core bits, which feature diamond particles bonded to the surface of the cutting matrix, excel in medium-hard formations like limestone and sandstone. Helvetic's surface set bits are known for their aggressive cutting action, making them popular for projects where speed is a priority. "We use synthetic diamonds with a high thermal stability rating," says Pierre Dubois, Helvetic's sales director. "This means our bits maintain their sharpness even when drilling in high-temperature conditions, like deep oil wells."
In addition to surface set bits, Helvetic produces carbide core bits for extremely soft formations, such as clay and silt. These bits use tungsten carbide tips for durability and are often used in environmental drilling projects, where preserving core integrity is crucial. The company's manufacturing facility in Lausanne houses state-of-the-art CNC machines, allowing for precise control over cutter placement and matrix density. "We recently partnered with a Canadian mining firm to develop a 94mm carbide core bit for permafrost drilling—they needed a bit that could handle frozen ground without fracturing the core," Dubois recalls. "The result? They completed their survey two weeks ahead of schedule." Helvetic also offers on-site training for clients, ensuring their teams know how to maintain and optimize bit performance.
Rhine Valley Drilling Supplies, based in Basel near the German border, has made a name for itself as a one-stop shop for PDC core bits and drilling accessories since 2005.
