Why Drill King?
Straighter Holes
The W60I will drill a straighter hole than a conventional air hammer, reducing hole deviation for precision projects
Ultra-High-Frequency
At 3,570 blows per minute, the W30I delivers incredible rock-breaking power
Reduced Formation Washout
Water evacuates the hole at a much slower velocity than air, reducing unintended washout of unconsolidated geology.
Fuel Efficency
Water pumps are significantly more efficient than air compressors meaning the same hole is drilled with less fuel and carbon emissions.
Configurable Wear Sleeve
Choose a smooth wear sleeve or one with integrated stabilizing ribs at a custom diameter to minimize hole deviation for your application
Sensitive Environments
No dust, dramatically reduced noise, and less formation washout make WAI hammers ideal for urban, underground, or structurally sensitive applications.
