Drilling components in mining require BÖHLER steels with high toughness, strength, and wear resistance. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable, long-lasting performance.
Drilling components in the mining industry, such as drill rods, bits, and tool holders, are exposed to extreme operating conditions including high impact loads, abrasive wear, and cyclic stresses in aggressive environments. Material requirements are therefore focused on exceptional toughness, high strength, superior wear resistance, and resistance to fatigue and crack propagation. In addition, resistance to corrosion and stability under varying temperatures are critical to ensure consistent drilling performance and extended service life in demanding underground and surface mining operations.
BÖHLER high-performance steels and alloys are specifically engineered to meet these rigorous requirements. Advanced quenched and tempered steels, wear-resistant tool steels, and specially alloyed grades provide an optimal combination of hardness and toughness for maximum durability and reliability. Produced using advanced melting technologies, BÖHLER materials offer superior cleanliness and homogeneous microstructures, minimizing the risk of failure under extreme stress. Key quality features include strict control of chemical composition, certified traceability, and precisely controlled heat treatment processes tailored to application needs. Comprehensive testing, including impact strength, wear resistance, and non-destructive inspection, ensures consistent performance. BÖHLER materials enable efficient, reliable, and cost-effective drilling operations in the mining industry.
BÖHLER K107 is a 12% ledeburitic chromium steel and corresponds to material number 1.2436 (X210CrW12). Due to the higher tungsten content, BÖHLER K107 achieves a higher resistance to abrasive wear compared to the conventional tool steel 1.2080. Compared to modern cold work tool steels, BÖHLER K107 has the advantage of simple heat treatment with lower hardening temperatures and single tempering. However, this characteristic tempering behaviour limits the use of modern coatings..
Read MoreBÖHLER K110 is a 12% ledeburitic chromium steel and corresponds to material number 1.2379 (X153CrMoV12, D2). This tool steel combines the advantages of conventional 12% ledeburitic chromium steels with those of advanced tool steels. In the group of 12% ledeburitic chromium steels, BÖHLER K110 offers the best combination of wear resistance, compressive strength and toughness, for which reason it is used in virtually all cold work applications. Its advantageous tempering behavior with a pronounced secondary hardness maximum also enables the use of advanced coatings. This also makes BÖHLER K110 suitable for complex tools requiring a high degree of dimensional stability and shape stability.
Read MoreBÖHLER K305 belongs to the group of 5% chromium steels and corresponds to the material 1.2363 (X100CrMoV5, A2). Compared to conventional tool steels with 1% carbon and low chromium content, BÖHLER K305 has significantly better through hardenability and wear resistance. This class of 5% chromium steels is used in situations where grades like 1.2842 are no longer sufficient in terms of wear resistance and through hardenability but materials like 1.2379 are not yet required. BÖHLER K305 is used for punching and cutting tools, die plates and inserts, thread cutting tools and machine knives in the wood, paper and recycling industries.
Read MoreBÖHLER K390 MICROCLEAN is a high-alloyed, high-performance cold work tool steel manufactured using powder metallurgy. This material has the highest alloy content in the group of cold work tool steels with high vanadium content. The high alloy content gives this material outstanding wear resistance. At the same time, the powder metallurgical manufacturing process creates a uniform matrix with finely distributed primary carbides. Among other things, this leads to good material toughness. BÖHLER K390 MICROCLEAN is a problem solver for applications requiring extremely high wear resistance and compressive strength.
Read MoreBÖHLER K455 corresponds approximately to the material 1.2550 (~60WCrV7, ~S1) in terms of the alloy concept. This classic matrix steel is characterized by high toughness, good machinability and polishability. BÖHLER K455 offers the advantage of simple heat treatment with low hardening temperatures and single tempering. BÖHLER K455 is widely used in the field of punching and cutting tools as well as in the field of embossing tools.
