24-Inch DTH Hammer

Drill King’s largest and most powerful DTH hammer, for 24″–34″ (610–864 mm) bits. A 1,150 lb piston and cylinderless internal design deliver the highest impact energy in the lineup with simplified field maintenance.

18-Inch DTH Hammer

Ultra-class DTH hammer for 18″–24″ (457–610 mm) bits. The 717 lb hardened piston — the most powerful in the Drill King lineup — delivers maximum energy per blow at 1,100 blows per minute.
15-Inch DTH Hammer

Drill King’s largest-class DTH hammer for 17″–20″ (432–508 mm) bits. A 528 lb hardened piston delivers more energy per blow than any other hammer in the lineup, at 1,140 blows per minute.
10-12-Inch DTH Hammers

High-energy, high-torque hammers for 9.5″–18″ holes. Six models across NUMA 100, SD10, SD12, IR112, and QL120 shanks — plus the large-bore HADK-T125N — all on a common 6⅝” API REG PIN connection.
Wing King

Cased holes through the toughest overburden. A simple, robust 2 & 3 wing cam-sliding design covering casing OD from 4.5″ to 36″ — the widest range in the DKI casing line, in permanent or retrieved configurations.
Ring Bit

Precision casing through overburden. Heavy Duty Ring Bit, Casing Shoe, and locking Pilot Bit form one oversized cutting face — Standard (4.5″–24″) and Pass-Thru (4″–12″) configurations, permanent or retrieved.
2-Inch DTH Hammer

Drill King’s smallest DTH hammer — a compact, valved BR2-platform tool for 2.75″–3.5″ (70–90 mm) bits, optimized for low-pressure operation from 100 PSI with the lowest air consumption in the lineup.
