What is the Best Tungsten Grinder

Diamond Ground Products has been manufacturing the best tungsten grinder product line for as long as there have been tungsten grinders. We saw the industry need in 1992 when we first opened our doors as "The Tungsten Electrode Experts".

Back then, most people sharpened their tungsten electrodes on more crude options, such as belt sanders, rotating rock grinders or even their standard all-purpose shop bench grinder. While functional, it wasn’t the safest way to sharpen tungsten and consistency was not easy to achieve.

We experimented with the chemical sharpening solutions. We even managed to keep most of our fingers. The process required using a propane torch to get the electrode red hot and then dipping it in and out of a chemical powder until electrode began to taper. Consistency was impossible and the fumes from the caustic mixture were terrible. This was NOT the best tungsten grinder.

We were there when the first benchtop tungsten grinder models with diamond wheels were introduced, and are proud to have been one of the first companies to offer a quality solution to the welding industry. Our DGP tungsten grinders that we sold then are very similar to the ones we still sell today.  These benchtop grinders were durable and offered extreme precision & repeatability. Undoubtedly, they were the best tungsten grinder to that point in time.  The downside? To some the cost was prohibitive and some models – especially ones with vacuum dust collection – weren’t the best tungsten grinder to get on a job site or any location that required mobility.

It was only a few years later that the smaller, hand-held options came upon the scene. Their price was attractive but their durability and consistency were not. Good in a pinch and nice to take to a job site, but not ready for the precision applications or for use by more than one welder. In many ways, the majority of these tungsten grinders were a step back in the evolution of tungsten grinders.

The Best Tungsten Grinder?

During this tungsten grinder journey, Diamond Ground Products started working on the Piranha Tungsten grinder. Bigger, more durable & more precise than a handheld tungsten grinder…yet smaller and more cost effective than the traditional benchtops. We couldn’t keep them in stock. The best tungsten grinder? Maybe, but we weren’t satisfied yet.

Over the years we’ve continued to innovate and improve the Piranha tungsten grinder, first with the Piranha II and now the Piranha III. After 20+ years of listening to customers needs and rigorous testing, we’re quite confident that the Piranha III tungsten electrode grinder is the best tungsten grinder on the market.
