Loved your 10 inch blade so I wanted to try the 8”! Love it also! Rocks!!!!
I recently acquired a 1952 Lortone LS-14 Lapidary Drop Saw. It needed a lot of TLC to get it back into working condition because it had been sitting for over 25 years. My final decision was what lapidary saw blade would be best for my Vintage Lortone saw. I absolutely made the right decision with the Gemking 14 inch Lapidary saw blade. The blade cuts smoothly and cleanly and cuts through my rocks with no problem whatsoever. I would recommend Delta Diamond and Gemking Lapidary blades.
I used to avoid working with Jasper or agate rough, always ended up dealing with pre-slabbed pieces, my blade just wouldn’t cut it! (see what I did there!)
Your saw blade is fantastic! Cut Jasper, agates, Wonderstone, and other extremely hard rough I’ve had for years, but avoided even trying to cut them because the blades I was using would eventually trip my saw and cut out! Frustrating! No longer. Thanks! I love it
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.
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!
Great Customer Service.
I ordered the wrong size diamond saw blade, but didn’t realize it until 6 weeks later, when I went to install it. I called the company and explained my mistake. They worked with me, very fairly, with swooping out with the correct saw blade size. I am greatly appreciative.
Since highland park has no blades available for months, I decided to go with this blade. It cuts well, though the blade has a flimsy note.. it also came warped, upon ruining a couple cuts I was able to send back for full replacement, this blade is not warped so thankyou. Ill be happy if it lasts a while. The reason for 3 star, is it took almost a month to get replacement, in that time my saw screws have disappeared and now I have to replace them. BIG HEADACHE! ill think twice before purchasing again. I go through blades like candy, and cut all day everyday, I need good blades and good service always.
Had a great experience from start to finish. Haven't installed the new blade yet because my saw is getting repaired. I'm excited to test it out soon. Thank you for a smooth transaction
The oil we ordered came quickly and reached our street address with no problems. Living in a very rural area brings delivery challenges at times. The bushings arrived separately but very promptly. The saw is working perfectly with this correct oil. We are pleasantly surprised that much less oil is needed for a cut than we anticipated. Thank you for the prompt service.
