Q: Where are Diamond Ground Products grinders made?
A: We have designed and built our tungsten grinders at our factory in Newbury Park, California since 1992. Since we manufacture in our facility and don't simply import and pass through to end users, we are in complete control of their quality and continued innovation. This also ensures that spare parts and domestic support are little more than a phone call away.
Q: How do the hand-held grinders compare to Diamond Ground Products grinders?
A: The numerous hand-held grinders on the market are good as disposable “hobby type” grinders. Diamond Ground Products grinders are professional quality and designed for continuous use in professional environments.
Q: Does Diamond Ground Products take trade-ins in exchange for DGP grinders?
A: Yes, if you have a grinder you are not happy with - whether it is running or not - give us a call for a no-obligation quote.
Q: How do you know which Diamond Ground Products grinder is right for you?
A: Each grinder page on our site has a link to a “Compare Tungsten Grinders” overlay that will show you grinder differences in regard to features and benefits. However, the best way to figure out what is the best grinder for you is to simply give us a call. We'll listen to your needs & your budget, and offer you the right grinder based on our expertise. Furthermore, we won't sell you anything more than you need. If you can get by with a hand-held model, we'll let you know before you ever have to tell us.
Q: I saw a site saying their grinder and Diamond Ground products grinders were like comparing “apples to sand”. What gives?
A: One of the downfalls of the internet is that people can write “puffery” whenever they want with little or no recourse. The truth of the matter is that we were one of the first to create the product category, manufacture on-site and are at the forefront of product evolution since 1992. We'll put our product up against anybody, especially people who do little more than sell other people's products. Ask about a demo and compare for yourself.
Q: Where does Diamond Ground Products tungsten come from?
A: Diamond Ground Products has 3 major suppliers of quality tungsten:
Sylvania / GTP® - Made in the US
Wolfram Industries® - Made in Germany
Plansee® - made in Austria
On some occasions, we also may import tungsten from China upon customer requests, and we have numerous companies we can work with.
Q: Does Diamond Ground Products tungsten come with material certifications?
A: Yes, all DGP tungsten - regardless of the supplier - comes with both material certifications and material safety data sheets (msds). We believe transparency in this regard is one of the many ways in which we earn a customers trust.
Q: What makes Diamond Ground products pre-ground Tungsten Electrodes different from other providers?
Quality & experience. DGP professionally CNC grinds our tungsten to the strictest tolerances on the finest equipment in the industry. Furthermore, DGP was founded in 1992 to specialize in tungsten & tungsten preparation. We don't claim to be experts in cool welding helmets or have the largest library of welding DVD's on the planet. We do not include candy with every order. What we do however, is provide the highest quality tungsten electrodes at a fair price and offer decades of experience in the subject matter when you need it.
Q: Is Multi-Strike® or similar of tungsten marketing as “non-thoriated tungsten” the same as Diamond Ground Products Tri-Mix® Tungsten?
A: No, these are all Tri-Mix copies that are made in China. You will see these sold under different names such as “Hybrid” and most have a blue, sky blue or turquoise paint on them. We find that particularly odd since the American Welding Society says such color coding is reserved for 2% Lanthanated, which we also offer if you require it. Either way, if you're ever not sure what you are buying or where it is coming from, simply ask for material certifications. If the company won't give you them, you may want to avoid them.
