Review on 💎 Premium Cutting Performance: KEMPSTON 88034 Kempston Diamond Saw by Michael Radhakrishnan

I had to cut two new faucet holes in my Kraus stainless steel sink, also through a thicker support rod. Stainless steel was very strong and shattered things like Milwaukee drill bits, withstood many burrs and abrasive dremel points, etc. It was a tool that survived and eventually got the job done. It took a while (minutes per hole), with lots of slow motion, low pressure, coolant application and reverse motion to cool things down, but it happened. It doesn't matter if it's slow as long as it doesn't wear out. I'd say less than 15% wear after drilling these two holes, which is great as other tools wear on nubs without leaving dents. If you need to punch a recess, this is what you need.
