Percussion drilling set, HM1812, RD32

With the percussion drilling set for heterogeneous soils with 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, up to a depth of 5 metres. Even in harder soils possibly containing layers of rubble and/or stones*. This makes this set very suitable for use in city centers and industrial sites.

The advantage of the electric hammer is that no petrol fumes and exhaust gases come directly over the sample. With this set, you get nice clean samples without using lubricants. The percussion drilling set is not intended to replace diamond core cutting and is not suitable for fibrous material. Please note that porosity is needed (displacement technique), not for dry glacial loam.

RD32-connection

The Royal Eijkelkamp percussion drilling sets 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.

* Please check that the stones and/or bricks do not exceed the diameter of the percussion gouges too much. If the stones can be pushed aside by the cutting shoe, or they can enter the gouge, there's no problem. Too large stones, or bricks that can not move, shall block the drilling and most likely break or damage the cutting shoe on the percussion shoe. However, cutting shoes can easily be replaced.
