High-frequency, high-torque performance for large-diameter drilling programs. Six models share a common 6-inch platform — HADK-A600I, A600S, A600Q, A600QHD, T600UCQ, and T600UCQ-HD — covering IR360, SD6, QL6, QL6HD, and QL60 shank standards.
Drill King International’s 6-inch DTH hammer series delivers high-frequency, high-torque performance for large-diameter drilling programs across Mining, Water Well, Construction, and Geotechnical applications. Six models share a common 6-inch platform, differing in bit shank compatibility and build specification: HADK-A600I (IR360), HADK-A600S (SD6), HADK-A600Q (QL6), HADK-A600QHD (QL6HD), HADK-T600UCQ (QL60), and HADK-T600UCQ-HD (QL60 Heavy Duty). This breadth lets operators standardize on a single 6-inch platform while selecting the exact shank standard and build rating their bit inventory and project conditions require.
Built from premium alloys with precision heat treatment, the 6-inch series delivers consistent impact energy at 1,455 blows per minute across a 150–350 PSI working range. Drill King’s Repair & Rebuild kits keep all models field-serviceable, minimizing downtime on demanding production sites worldwide.
Available for easy and cost-effective field maintenance across all six models.
1,455 blows/min for fastest penetration rates in 6-inch class drilling.
IR360, SD6, QL6, QL6HD, and QL60 shanks supported across standard and Heavy-Duty (H.D.) variants.
Shared across the A600 platform, simplifying training and field diagnostics.
Available for project-specific requirements.
All wear-critical components treated for extended service intervals.
QL6HD and T600UCQ-HD models feature reinforced wear sleeve and drive sub components for high-torque or abrasive applications.
T600UCQ and T600UCQ-HD eliminate the internal blow tube for increased reliability.
1,455 blows per minute and high rotation torque built for the sustained, high-energy demands of production mining blast-hole and quarry drilling programs.
Broad working pressure range and reliable air distribution make the A600 and T600 platforms a strong fit for municipal, agricultural, and industrial water well construction.
Open hole or cased hole operation supports piling, ground anchoring, and site investigation work where bore stability and diameter consistency are essential.
High-frequency performance and multi-shank versatility suit road, bridge, and civil infrastructure drilling projects.
