The carbide material ensures a long service life of the hammer drill even with high operating load or work in iron armouring - The dynamic chisel-shaped drill head penetrates the material quickly and reduces vibrations, which significantly increases drilling efficiency - The patented multi-helical KVS helix is symmetrically shaped over its entire length, which leads the drill dust quickly out of the borehole - The energy transfer to the carbide plate is optimized thanks to the special core-reinforced helical geometry, which means that the drilling speed and longevity of the tool are significantly increased - Thermal treatment and special surface compaction of the hammer drills reduce wear and tear - Drills are extremely resistant to bending!
