DTH Foundation Equipment & Complete Solutions
Bench blasting is won or lost on three numbers β hole diameter, bench depth and rock hardness. Tell us those and we size the rig, the air package and the tooling as one system.
Foundation piling pays for diameter, not depth. Pick the hammer and bit to the pile diameter, then size the rig to the reach.

What Determines the Right Drill Rig?

1. Diameter sets the hammer
Pile diameters in the 300β800 mm range are common in foundation and anchor work. DTH is chosen where rock is hard, where refusal layers occur, or where the profile must be drilled through boulders.
| Pile diameter | Method | Rig class |
|---|---|---|
| 300β600 mm | DTH with large hammer | Mid-size crawler or dedicated piling rig |
| 600β1000 mm | DTH with big hammer | Heavy carrier |
2. Air volume scales with diameter
Bigger bits clear more cuttings, which needs more air. Under-supplying air is the most common cause of slow penetration and worn bits on piling jobs.
3. Site access decides the carrier
Urban and hillside sites often can't take a heavy machine. A compact rig with a big hammer is frequently the better answer than a large rig that can't reach the pile position.

Matching Air Compressors
Air demand is set by the hammer, not the rig. Discharge pressure must cover the hammer rating and free air delivery must cover air consumption plus margin.

Rig selection
Which drilling rig should I use for foundation piling?
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 115β254 mm), KT20S (hole 135β254 mm), KT30 (hole 195β254 mm). Send us hole diameter, depth and rock type and we will confirm the fit.
Which drilling rigs are recommended for foundation piling?
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), KG940A (up to 203 mm). Final selection depends on hole diameter, bench depth and rock conditions β use the equipment selector for a parameter-matched shortlist.
What is the maximum drilling depth for foundation piling?
The deepest published capability among the listed models is 25 m (KG430, KG520). 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.
Which drilling tools match the rigs used in foundation piling?
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.
How many models are available for foundation piling?
15 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.
Hole diameter
What hole diameter range can be drilled?
Across the rigs we list for this application the published hole range spans 32β254 mm. Depth capability and rock hardness decide which end of that range applies β tell us the diameter and bench depth and we will match the model.
What hole diameter range can be drilled in foundation piling?
Across the rigs listed for this application the published hole range spans 90β500 mm. Smaller diameters favour mid-size rigs with higher drilling frequency; larger diameters need a heavier carrier and matched air volume.
Air compressor
What air compressor is required?
Air demand is set by the hammer, not the rig. The compressors we list for this application cover 5β45 mΒ³/min and discharge pressures from 8 to 35 bar. Match the compressor's free air delivery to the hammer's consumption (plus a 10β15% margin) and make sure discharge pressure covers the hammer rating.
What air compressor is required for foundation piling?
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.
