Covington's Gold Series Diamond Blades are excellent quality, commercial-grade blades designed for lapidary work. More diamonds in the notched rim and a stiffer core make this blade cut faster and maintain a longer use life. While this blade was designed for use on hard materials like agates, geodes, and petrified wood, it will cut softer materials superbly. The gold series blades are a great, low cost option.

  • 12" through 16" blades have a 1" - 5/8" arbor 
  • 18" + are available in 1" -3/4" arbor 
Covington's 6" and 10" saws come standard with our gold series blade. These blades are the most economical choice for a wide range of lapidary cutting needs.

Awesome Blade

Dana Foster on 2nd Sep 2018

I got his blade to cut agate and petrified wood, it has surpassed my expectations. The cut is really smooth and fast. I love it and am planning on replacing the blades on all my saws with these blades.

Good product and quick service

My second gold blade.

12th Sep 2017

Yeah, I'm on my second Gold blade I had a rock slip out of the vise and bent the first blade. First blade was doing a fine job of cutting sorry to see it go. Have made a few cuts with the new blade and it seems to be cutting just as good as the first blade. A good blade and a good price. A 12" blade.

Good and not so good

I have a 14" gold on my Lortone drop saw, water cooled, not so good, can't keep it dressed. I also have a 20" gold, oil cooled and it works great.

Covington 18" Gold Blade

Dan Schreiner, on 1st Jun 2017

I just received my first Covington Gold Blade. The condition was near perfect and it runs true. My first jade slabs were great. I'll be interested in testing it long term on all types of jade material. The shipping time was extremely quick by FedEx and that was very much appreciated.

So far, so good.

Covington Gold blades are of the best quality and durability on the market. They far outdistance the competitors in pricing, wear, and the quality of precision cutting. I am also extremely pleased with company's personalized attention to their customers needs and requests.
