Description:

The Minerza bit is engineered for consistent, deep drilling performance across a wide range of rock conditions. Its extended head geometry and reinforced carbide seating provide optimal support and even load distribution, minimizing premature wear and breakage. Manufactured from heat-treated nickel-molybdenum steel, the bit maintains shape stability and delivers smooth, aggressive penetration. Advanced CarbideMax inserts increase service life by up to 45%, while the deep-groove face design ensures efficient cuttings removal and superior flushing.
