Review on 💪 Efficient Cutting with Greenlee 625 7 Carbide Tipped Cutter - 8 Inch by James Wiley

I've used (and abused) countless cutters to drill holes in metal. They cut well but the mandrels are weak and the bits wobble and don't make a clean round hole. Also, with the exception of cutters with an attachment that must be used in a drill press or a milling machine, they dull quickly even with a large amount of oil. This Greenlee cutter is awesome! I've used both cordless and corded hand drills to make holes in 18 gauge steel. The pilot drill surprisingly works as advertised as it doesn't require a centering hammer to hit the target accurately and doesn't run around. The cutting tips cut through steel like paper. Anyway, it cuts so hard that you have to be careful not to put pressure on it because it will pierce too quickly and stop immediately, but even then it won't damage the cut hole or change shape. When he finally cut the end of the hole, the opposite side came through clean and smooth with no deburring required. The resulting hole looked like it had been punched with a press. This cutter is very quiet when cutting unlike any other I have used. It cuts like a drill and removes long chips instead of tiny steel particles. The built in stop is a nice feature, but it limits the depth of hole you can cut to around 3/4 to 1 inch. Cutting edge and shank are made from one piece, which ensures stable and vibration-free running of the cutting edge. The pilot drill goes in and reaches the shank. The flat surface of the center drill prevents the drill from rotating and because it rests against the shank it cannot slide up when drilling. This provides more stability, but also means that you cannot adjust how far the pilot drill protrudes beyond the cutter tip. I had several holes in the inner panel and the pilot drill went too far out of the router bit and drilled through the inner panel as I made the hole. So I used a 1/4 shoulder screw to make a guide that protrudes a little past the cutting edge of the router bit. I started cutting with a Greenlee pilot bit and then replaced it with a solid pilot bit that I fabricated to finish the rest of the hole. It was a little uncomfortable, but I still prefer a solid pilot drill mount that doesn't slip, so it's worth the inconvenience. packaging (wish it was stamped on the cutter) and using lots of oil. I've only made half a dozen holes so far, but I'm sure this thing will stay sharp for many, many more times. I was hesitant to spend that kind of money on a hole cutter, but after using it I wish I had known about Greenlee cutters earlier and spent the extra money years ago. Try it, you will like it! I bought a few other regular smaller sizes to replace my other cutters. The larger sizes are too expensive for me at the moment.
