Review on 🔪 Effortless Cutting Precision: EZARC Carbide Cutter for Heavy Stainless Materials by Mark Jefferson

We needed a hot water tap hole in a new stainless steel sink. I bought this drill based on other recommendations I saw and I'm glad I spent a few extra dollars on it because it worked great. Here are all the different tips that we've found useful from our personal metal cutting experience, along with items I've picked from other reviews. * Use engine oil. We applied enough Forney 20857 Tap Magic Industrial Pro Cutting Fluid to leave a small puddle/shiny layer all over the work surface and edges of the drill bit and hole saw as we drilled. around with. You'll also need a decent supply of paper towels or disposable rags to help you clean up on the go. * Place a rag under the drill bit to catch metal shavings and excess oil. That was a very smart tip that helped with the clean up. This stopped the bat from migrating. * Keep your speed slow. We used a Dewalt 20V cordless drill with a gear ratio of 1 (lowest speed, highest torque). We drilled at about 3/4 speed so the center drill went through the metal, then kept the speed below half trigger force once the drill touched the metal. We didn't put much effort, stopping from time to time to wipe off excess shavings. Then we reapplied the oil to make everything move smoothly. One of the reviews we read says that care should be taken not to heat the metal as this would stiffen the metal and make drilling difficult. Another said to make sure there is no smoking as it means there is too much friction. With the above steps, we didn't encounter any of the issues. It took about a minute or more to pierce the center hole and about seven more minutes to cut the hole. The end product was a perfectly smooth hole. The teeth of the hole saw are still perfectly sharp.
