Review on ⚡ Copper Stainless Drill Speed Cutting - Optimize Your Drilling Efficiency! by Steve Campbell
HSS will not cut through metal
55mm hole saw failed to cut through control panel switch box. I used cutting coolant, slow speed, and the teeth that started to sharpen were flattened significantly. I stopped drilling to save the drill for future use in wood or aluminum.
Pros
- Tools and Household Goods
Cons
- High Price
