Colli - Down the Hole Hammers

This year we are pleased to introduce our new line of down the hole hammers: Destroyer Series. They are the result of years of research and implementation of the latest technologies that make them unique in their kind and able to compete with the big brands in this sector. The state-of-the-art production plant uses top quality heat treated steels in Nickel-Chromium alloy and processes that meet ISO 9001: 2015 standards. This process of excellence ensures the reliability and longevity of every single hammer. Our deep hole hammers are born with different attachments and to adapt to different needs: MACH, DHD, SD, QL, and Mission.
