Review on 🔪 LDEXIN Triangle Cutting Tungsten Carbide: Precision and Durability for Cutting Purposes by John Kennedy

I've found this in soft drilling from 1/4"-3/8" uses a steel diamond plate, and so I needed identical halves; There were two sheets back to back (double thickness) at the same time. I used a drill press, the slowest speed, and light pressurized oil. Cuts aggressively and takes about five minutes per hole. The bit doesn't even look like it's pierced through, it still looks like new. I like the flattened shank for a secure fit on the lining. ? Not a big deal to me, actually helps my situation. I used a press so it didn't rock. Second, it will NOT drill into wood. I used a 2x4 underneath the steel I'm cutting and once the robot hits the wood grain it just rolls off. It's not for wood, but I figured it out. Overall very happy with the performance and purchase.
