It depends on hole diameter and depth. In our current range, 29 rig models have a published hole range for this work; the largest-capacity three are KG550 (hole 115–254 mm), KT20S (hole 135–254 mm), KT30 (hole 195–254 mm). Send us hole diameter, depth and rock type and we will confirm the fit.

Based on the published hole range of the rigs listed for this application, the widest-coverage models are KG500GF (up to 500 mm), KG550 (up to 254 mm), KT30 (up to 254 mm). Final selection depends on hole diameter, bench depth and rock conditions — use the equipment selector for a parameter-matched shortlist.

The deepest published capability among the listed models is 36 m (KT15C, KT25). Note that economical depth depends on method and tooling: a split rig with a separate compressor is normally economical to about 25 m per bench, while deeper holes need matched rod strings.

The parameter-matched tooling for the listed rigs is hammers: K40, K10; bits: K40, K10; rods: 76mm Drill Rods. Tool selection follows the hammer class and the required hole diameter.

37 rig models are currently listed against this application, and matched compressors, hammers, bits and rods are linked to each of them. The complete package can be assembled and quoted as one configuration.

Across the rigs we list for this application the published hole range spans 32–254 mm. Depth capability and rock hardness decide which end of that range applies — tell us the diameter and bench depth and we will match the model.

Across the rigs listed for this application the published hole range spans 64–500 mm. Smaller diameters favour mid-size rigs with higher drilling frequency; larger diameters need a heavier carrier and matched air volume.

Air demand is set by the hammer, not the rig. The compressors we list for this application cover 5–45 m³/min and discharge pressures from 8 to 35 bar. Match the compressor's free air delivery to the hammer's consumption (plus a 10–15% margin) and make sure discharge pressure covers the hammer rating.

Air demand is set by the hammer, not the rig. Parameter-matched compressors for the rigs in this application include LGCY-19/21-21/18, KSZJ-27/23-30/17K, LGCY-17/18-18/15T. Match the compressor's working pressure and free air delivery to the hammer class you intend to run.
