Review on Ultimate Protection: Hymnorq 🛡️ Enhanced Hardness Resistance Stainless Steel by Bill Dahl
Better than expected
For drilling in grade 9 titanium they work well. I was able to drill 6 holes with the 1st drill. 1.5 with the second and finish the project with the 3. For the price of these bits an average of 3 holes per bit is acceptable.
Pros
- Decent performance
Cons
- No performance
