Why Drill King?
Superior Technology
The HADK-150 delivers more energy per blow, translating directly into faster penetration on the largest hole diameters Drill King offers.
Hardened Piston
A hardened piston extends component life under the sustained high-torque loads typical of 15" drilling.
Massive Rotation Torque
10,000 lb·Ft (13,560 N·m) of rotation torque drives the largest-diameter bits through the toughest formations.
Robust SD15 Shank
A dedicated SD15 shank design matches large-diameter rigs without custom tooling.
Maximized Uptime
Repair and rebuild kits keep the hammer field-serviceable, minimizing downtime on the largest-scale projects.
Extended Component Life
Premium alloys and wear-resistant surface treatments extend tool life and reduce operating cost on large-diameter tooling.
