Hydraulic Augers
HKM hydraulic augers fit 1-45 ton machines with 2,000-48,000 Nm torque for drilling and driving. High efficiency in planting, fencing and foundation work.
HKM hydraulic augers deliver high torque, low maintenance and precise drilling for ground boring, pile pre-drilling, fence posts and landscaping. With 8 models from AG20 to AG500 and carrier-specific bracket options, they work safely and efficiently from mini excavators to large machines.
The high-torque drive unit ensures steady advance with a wide oil-flow range and an optimized gearbox, while the compact, balanced body provides low vibration and safe operator control. The pinned connection enables fast bit changes on site, and a broad range of bits and extensions (D200-D500, 1200-2300 mm) adapts to every soil type.

This tool performs a pre-selection based on catalogue values and is not a binding quotation. Attachments without a hydraulic supply, such as rippers, have no flow or pressure rows; those models are unaffected by the flow filter. The final choice is made together, based on material, workload and the hydraulic equipment of the carrier.

Frequently Asked Questions
What is a hydraulic auger used for?
For precise, fast holes in the ground; common in piling, posts, tree planting and foundation work.
Which auger should I choose for my carrier?
The right motor and auger tool are set by carrier tonnage, diameter and ground type. Share your machine and we will recommend the set.
Are different tools needed for soil and rock?
Yes. An earth or rock auger tool is used by ground hardness; the right tool improves output and life.
