Holer Diamond Tools is based in Nelson, New Zealand, and was founded by Fred Holer in 1992. We are still a family owned and operated business but it is now run by Fred’s sons Phil and Simon Holer. 
Fred started the business as an import company specialising in diamond tools. But we have since then moved into manufacturing locally and installed our robotic laser welding machine in 2014 - at the time, the only one in the southern hemisphere and one of just eight worldwide. 

The 25+ strong team at Holer Diamond Tools is focused on providing you with the right solution for your diamond tool needs. Manufacturing locally is an important part of our solution driven approach:

• We can manufacture diamond tools that are specifically made for NZ aggregate and conditions
• Most of our tools are high-tech laser welded, providing safety and the strongest adhesion to eliminate segment loss
• We have full quality control and are thereby able to provide you with high quality tools - every time
• With a laser engraver on-site we can deliver our tools with permanent marking and identification of safety guide as well as max. rpm, rotation and manufacturing batch number
• We are able to manufacture custom-made solutions with a quick turn-around time of usually only 24 h
