Atlas Copco DKR 36

The quick-release chuck is a money saver. It helps you change between drilling and chipping operations and you can do more work in shorter time.
Lubrication is especially important to think about when you are drilling. With the DKR 36 you can concentrate on the task at hand. A built-in lubricator lasts a whole normal shift and helps keep the drill chipper and tools in shape.
There is almost always a use for it, and the weight helps you work in almost impossible positions. You can go overhead or under water. Divers especially like this model because they can do so much with it – anything from underwater drilling to chipping – thanks to low feed force. - Less
