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.
