Percussion drilling set - hammer Cobra TT, RD32

Description

The percussion drilling set is perfect for soils with bricks or large stones, which makes it suitable for use in urban areas or industrial sites, for example. With this drilling set you get beautiful clean samples without the use of lubricants.

The set is equipped with extremely robust rods and gouges. The different diameters allow efficient, fast and light work. Please note that this set does not replace cutting with a diamond core and is not intended for fibrous material. Do not use the set on dry glacial loam, porosity is required.

RD32-connection
The 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.
