Review on 🔳 16Mm 53Mm Hole Saw by Drill Warehouse by Jose Strong

My project involved drilling some vent holes in 12 gauge sheet metal, I just needed enough to let air through so dimensions were not critical. I just don't have a plasma cutter like my fashion friends. The carbide teeth cut really well and hold up really well. They really cut. The secret of carbide is that you have to work with them a little faster than with steel tools to keep them happy and apply less pressure. They'll penetrate 12-gauge steel in no time. The downside is that these tools are basically just castings that will be cleaned up a bit, and runout is something left as an exercise for the end user. That means you're exercising a lot trying to keep these things steady while they're vibrating with your whole body. For example they are marked "50.0mm" but I measured a runout of 1.2mm so the hole size may vary. Like I said, I didn't really care, but if you're making something with really critical sizes, check it out. If you work at the appropriate speed for carbide teeth, the drills literally melt away. I had three bits off and two more burned out completely. The hole saws themselves are fine and after I changed the center cutter they are fine again. I only plan to order additional services.
