Review on 🔪 MAGBIT 625 6416 MAG625 Carbide 16 Inch: High-Performance Cutting Tool by Justin Guldin

After trying (and failing) to drill a single hole in Hardie fairings with a bi-metal hole saw for 30 minutes and a drill motor due to overheating broke I decided to order a carbide tipped hole saw to see if it worked better. With this hole saw, I was able to drill all 8 holes I needed in less than 10 seconds with no noticeable bit wear. If you want to go through Hardie this hole saw is fantastic and I want to take back the time I wasted on useless bi-metal bits the other day.
