Review on 🔧 Koopi Bi Metal Drilling Tools & Hole Saws for Precise Plastic Plywood Cutting and Accessories by Alonzo Weaver

Hole Saw for drilling a steel wood core door to install a deadbolt lock. The hole saw has very aggressive teeth and easily cuts through both steel and softwood. The only downside to the smaller hole saw was the drill bit cleaning - the drill bit has to be removed to remove debris from the hole saw, which is not the case with larger hole saws as they have a large slot for removing debris. Visible wear only - the paint on the teeth has been removed, there is no wear on the teeth.
