Our rotary blasthole drills are productive solutions for all mine types. When you need to meet your drilling and blasting needs at the lowest cost per meter drilled, these powerful and reliable systems make P&H drills your best choice. Our powerful and rugged rotary carriages are able to provide ample torque and bit loading through the toughest rock conditions in the world. Difficult operating environments, such as arctic conditions, high altitude and weak power grids are no match for our drills. 

Powerful pulldown

  • Top-drive, rack-and-pinion pulldown has fewer wearing components requiring maintenance, contributing to better machine availability
  • Powerful rotary carriages provide ample torque and bit loading to break through the toughest rock conditions

Superior propel

  • Mainframes and crawler frames are built for maximum strength and stand up to the most challenging hard rock mine conditions
  • Rugged crawlers and powerful hydrostatic propel drives deliver maneuverability, gradability, and fast set-ups

Rugged masts

  • Drill mast is designed for high-cycle fatigue resistance, resulting in less downtime and lower costs for crack repair
  • Mast, constructed of high-strength alloy steel, provides maximum rotary carriage and drill string support

Excellent operator visibility and protective operator environment

  • Operator’s cab provides a clear, unobstructed view of the drilling area, including the areas surrounding the drill
  • Full windows, coupled with video cameras, ensure that your operator has maximum visibility during drilling and propelling operations
  • Operator’s chair can swivel to face the travel direction, allowing safer repositioning
  • FOPS Level II-certified structure and shatter-resistant glass protects your operator during harsh mining conditions
  • Operator controls are located within easy reach to allow for maximum productivity

Superior extreme environment capabilities

Options are available that make our blasthole drills ideal for some of the toughest mining conditions in the world:

  • Weak power grids: has a soft-start transformer available that reduces the initial inrush current, limiting the impact of starting the drill on weak power grids; this can reduce your overall power infrastructure costs and increase the life of the main motor and compressor (320XPC model)
  • Arctic conditions: equipped with the necessary heaters and insulation to protect both your operator and the drill in temperatures that reach -40°C (-40°F)
  • High altitude: has the power and air capacity to maximize productivity in altitudes up to 4572 m (15,000 ft.)
