With the percussion drilling set for heterogeneous soils with heavy electrical percussion hammer (HM 1812), the percussion gouges are hammered into the soil using an electrically driven percussion hammer with 72.8 Joule strike capability. The advantages of this hammer are: no petrol vapours and exhaust gasses directly over the sample. The set contains: an electrically driven percussion hammer with accessories, an aggregate (continuous power 3.4 kVa), an insulation guard, various extension rods, coupling sleeves, precussion gouges (combination type) in various diameters and lengths, a core sampler for PVC sample tubes and foil liners, a mechanical rod puller, an universal casing and rod puller clamp, a rod puller extension, accessories to empty and clean the gouge, a lifting jack with lever and chain, an utility probe for safe cable finding, stairs, and aluminium transport cases, etc. Benefits Percussion drilling set Ideal for soil with bricks, large or many stones The solution for city centres / industrial sites Beautiful clean samples, no lubricants used Extremely sturdy rods and gouges Diameters allow efficient, rapid and light work Can be combined with liner or foil sampling Remarks Does not replace diamond core cutting Not for fibrous material like (thick) roots Porosity needed, not for dry glacial loams Contact SonicSampDrill for larger depths RD32-connection The percusssion drilling sets of Eijkelkamp Soil & Water are equipped with RD32-connection extension rods and percussion gouges are screwed together using a coupling sleeve. The RD32-connection is used in firmer, dryer soils. The RD32-connection takes very little time to attach and take off. The RD32-rods connect together by means of a coupling sleeve, which means that the massive extension rods have the same diameter along the entire length, which makes them very strong.
