Customer photo review of Diamond Extreme All-Cut Metal Cutting Diamond Blade, Heavy-Duty All-Purpose Cut-Off Wheel for Metal, PVC Pipe, Rebar, Stainless Steel, Size 4-1/2" to 16"

Kirk S.

wish i could explain the photos better, they deserve captions. i bought 2 replacements for the blade on the dewalt, as i believed it was at the end of its life. the chisel was freshly sharpened for marking the 1/2 inch steel for the cut, i took a picture as circled because that is what happened when i hit the chisel, it barely dented the now i know is hardened steel. made 2 cuts with the used blade then after cut an oxygen tank open for recycling, took the top and bottom off using the same blade...

Jasmine A.

I can confidently say this is hands-down the best lapidary blade I’ve ever used. The cut quality is exceptional: fast, clean, and consistent, with virtually no chipping. Compared to my previous blades, this one drastically reduces both my cutting time and wear on my machine. The depth and integrity of this blade give me peace of mind with every cut, and I appreciate how its thin kerf design balances speed with precision. It also helps protect the longevity of my equipment, which is a major win ...

I am installing 900 sq ft of 6x36 tiles in my living room and kitchen. I called Tony at Delta Diamond to ask what blade I should use and he sold me this 10" Boss Hog and it works great!

Customer photo review of Gemking Lapidary Saw Blades with Ultra-Thin Notched Rim for Wet Cutting of Hard Materials such as Agate, Petrified Wood or Jade

William J.

Didn't realize how worn the old blade was until I started cutting with the new one. Cut's, super smooth and reduces the noise. I've learned one thing about lapidary blades that you should spend the extra money to get a good blade then buy cheap because they don't last. Although I can't afford it, I wonder how the $1,000 blade would work.

Piranha Glass Diamond Saw Blade saved my project! I had some thick pieces of Murrini glass that needed to be cut. This blade cut it like butter! I was so happy with this product and company. They communicate well and are so friendly. I don’t live far so I picked up my blade. They were welcoming and helpful with my questions. Happy customer❤️

Customer photo review of 5/8" Core Bit Adapter (1/2" Hex Shank)

Michael H.

The adapter worked great. Chuck size 1/2” or greater. I prefer the adapter to use with a drill rather than a grinder where the adapter is not needed. I can control both the angle and pressure better with the adapter and drill.

Michael H.

I tested the 1 3/4” bit today in 1 1/4” flagstone. It worked well. The holes were clean cut on both sides with very little chipping on the back side. Technique is important. To start low speed, at an angle to control the bit, gradually rotating to full contact. After full contact and the bit is not walking, changing to high speed, keeping stone wet. Took about 2-3 minutes per hole. The pics are front and back sides of same two holes.

Well I ordered the wrong size, but they were ready to fix that instantly. I love this blade. It cuts cleanly thru Adventurine, Amazonite, Lapis, Chalcedony and Agates ,Quartz and Granite. A great investment for rock cutters.

Needed to slot a heavy wall 1.25 DOM tube with .281 wall thickness quickly & consistently & at a 1/4" opening. Tried a milling process but took way to much time. Tried a tube laser but annealing occurred with lots of heat added to the part & a jagged slot face. So we found this diamond blade and gave it a try. On a Rigid table saw no less. Cut cleanly, cut quickly and didn't burn the part. Some sparks but cutting over a concrete pad & sparks didn't get to the floor. If we get the customer...

so long review, i have been using the 7" 5/8 arbor diamond extreme for years now, made a review on amazon, short version buy this. i was using dewalt composite cutting wheels until i found this, super difference, more straight cuts, less binding and throwing the tool into your wrist, thinner cut. i am super satisfied most things just work, this works phenomenally well. if you cut metal, and dont have one, get one. you will be pleased. functionality, the trailer is 1/4" angle iron by 2", i cut th...

Customer photo review of Stiletto Diamond Blade for Stone, Granite, Marble and Similar Materials, Size 10"

Daniel R.

I was using a 10" Piranha blade for natural stacked stone and it worked great but wore out relatively quickly. Tony at Delta Diamond reached out to me and switched me over to this Stiletto blade. The Stiletto is much thicker so it removes more material with each cut and makes more stone dust. It is also more rigid and maintains a straight cut better than the thinner Piranha blade. It is also more aggressive than the Piranha and after a day of cutting has showed no signs of slowing down. The...

Customer photo review of Piranha Premium Diamond Saw Blade, for Porcelain Tile, Ceramic Tile, and Stone, Wet or Dry Use, Continuous Rim, Sizes 3.375" to 10"

Daniel R.

This is my first experience installing stacked stone so when I started the job last year I asked a lot of people what blade to use and everyone had a different answer. I ended up choosing this 10" Piranha blade on my own because it was relatively inexpensive and looked good for the job. I went through 4 of these blades over the course of months because I installed a lot of stone. They cut natural stacked stone like butter for the first 20 cuts but then became steadily slower cutting until the...

This blade is a workhorse! Eats agates, jasper, everything. I cut over a hundred agates in one sitting, check out the cut on this Kentucky geode. Butter!

I picked up this blade for my high speed tile saw that I use for cutting my agates and jaspers. And i must say these perform very well, and i will be buying it again. Great blade!! I do "sharpen" the blade with a bastard file before every use. And it cuts like butter.

The part was on back order but customer service called me right away and let me know when it would arrive. Thank you for the communication it helped me plan my daily operations. Most companies never call or let me know any updates. Thanks for not making it a guessing game.

The blade cuts through the toughest material like a hot knife thru butter. Absolutely worth the wait and time it took to get it. Love it. Our club loves it. We made the right choice using Delta Diamond Products.

Mark W.

Ordered an 18" blade for lapidary work. This blade was among those with the best price. Later, I got an email about my cart not being empty so I called (it was a minor mix up on my part, not theirs). I was VERY pleasantly surprised when an actual human picked up and dealt with me in a matter of a few minutes. No 15 step stupid phone menu!!! If I need another, I won't hesitate to use Delta Diamond again.

I am tuckpointing a block wall with hard mortar, and this blade is grinding through the old mortar joints with ease. I am using the 3/8 inch thick six inch diameter wheel on a seven inch grinder.

I cut two 24 foot loops for my swing arm gate. The concrete was tough to cut but this blade was amazing on my old old saw. It took some time and effort but the blade did not fail me.

Planned to use the diamond blade with the "universal" Dust housing, but turns out it's not that "universal". I admit I have an older Skil angle grinder, but none of the adapters that came with the dust muzzle seem to work. The spindle on my grinder is too short apparently. This forces me to buy a new (or used) grinder that will work. The quality of the products seem fine. It's just annoying that I have to find a new tool. I did email the company if there was a particular component that wou...

Needed to grind down poorly formed concrete step and this wheel worked great! It cuts fast but leaves a fairly smooth surface. I needed a 4 inch wheel for smaller areas and this wheel saved me a ton of time compared to the cheaper Chinese blade I was using. I ground quite a bit of concrete and it stills looks almost new. For the price and quality Deltas diamond blades can't be beat!
