The service Nick provides is seconded to none. He knows the tools and products he sells and what he does not have he can source them in. A phone call is only required.

Diamach has a very wide range of good quality tools for the stonemasonry industry. I have been a stonemason working with sandstone for 43years and I highly recommend this company for helpful advice, fair prices and quality.

Michael Livisianos

We find Diamach a very efficient company, our purchases arrived very soon after ordering. Our only little hiccup was I found the specific grade diamond sanding blocks that I wanted really hard to find on their website, whole sets came up, which I didn’t want, but apart from that, a very user-friendly website. Many thanks Diamach.

Diamach is the best thing that has happened to the stone workers industry for many years. Nick knows the game inside and out and has all the necessary tools to get the job done that is not available anywhere else and at a very reasonable price.I have thoroughly recommended Nick to all my friends in the industry and would advise anyone in the industry to be sure to visit his shop in Roseville

Charles Brown

I highly recommend Nick and his staff to anyone looking for stone working tools and equipment.

Nick has a wealth of knowledge and the right products, materials & tools for the job.

He has a great range which is fairly priced.

I own a landscape business in Newcastle and have been buying diamond saw blades, stone working and cutting tools from Diamach for over 10yrs. Nic usually has the gear I require delivered by the following day which find awesome, occasionally it takes two days. His gear is always top quality. i cannot fault his service.

I am a builder working around Coffs Harbour.
Over the last few years I have struggled to find accompany to supply diamond cutting tools which I can rely on. One of my suppliers suggested I try Diamach, Sydney, as they have been using them for some time and are very satisfied with this supplier.
I contacted Nick who was very helpful with my requests for a number of diamond hole cutters which worked perfectly.
I ordered a 6mm diamond drill which turned out to be less than satisfactory, as the diamond bit failed whilst cutting through porcelain tiles.
I contacted Nick and sent pic’s, he immediately forwarded a replacement bit, at his cost.
That is what you call service!
I have been telling other builders etc. about Diamach and how they are so professional in their business
I highly recommend Diamach.
Thanks Nick
