Holer Diamond Tools

Holer Diamond Tools Holer Diamond tools is family owned and operated business specialising in diamond tools and machinery for concrete drilling, cutting and grinding.

We produce all our concrete core drill bits and grinding shoes locally in Nelson, NZ. www.holer.co.nz Holer Diamond Tools 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 20+ 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 can manufacture custom-made solutions with a quick turn-around time of usually only 24 h

Custom-made tools. We can provide customised solutions outside of the standard Holer specifications to get the job done. Our team of experienced and dedicated toolmakers can manufacture your customised diamond tool. For instance, we can manufacture diamond core drill bits with a shorter or longer than standard usable length of up to 3,000 mm. The largest diameter manufactured to date was Ø 1,000 mm. The turnaround time is usually only 24 h. Repair service. Our tools and equipment are backed up by our team of fully qualified technicians. They are here to help if your equipment needs servicing or fixing. And with most spare parts in stock, we can ensure a quick turn-around time which means as little downtime as possible for you. In most cases the repair only takes 1-2 working days. Should there be any delays, we offer loan equipment to bridge the gap (subject to availability). We not only service machinery but also repair your diamond tools. This service includes saw blade tensioning, re-tipping and body balancing. Staff training and large project support. With years of experience, we can help you with training for your staff or assist you with a large project. We run training sessions at our head office in Nelson, but we can also come to you. We can help you with wall and wire sawing, core drilling, hand sawing, concrete grinding and floor polishing.
