Their "progressive" design utilizes a stepped cutting edge that gradually fragments hard materials, maximizing drilling efficiency in challenging ground conditions. esign & Features Progressive Cutting Edge: A stepped flight profile lined with round shank chisels allows the tool to cut into rock in distinct stages rather than all at once. Pilot Bit: Typically equipped with a heavy-duty pilot bit (such as the RP4) to precisely center the auger and guide initial penetration. Wear Protection: The flights are heavily reinforced with hard facing and wear strips to prolong the tool's lifespan in highly abrasive environments. Double-Cut Options: Models feature a double-cut design, which provides better balance and is highly recommended for larger drilling diameters or when operating in uncased bores. Rig Connection: They connect to the Kelly bar of rotary drilling rigs using standard couplings, commonly a 200 mm Kellybox. Primary Applications Hard Rock Excavation: Specifically rated for breaking through moderately strong to strong rock formations, typically handling compressive strengths between 50 and 100 MPa. Deep Foundation Piling: Used extensively in Kelly drilling operations to create large-diameter bored piles for structural foundations.
