Review on 🪚 STROTON Titanium Nitride Stainless 1mm to 10mm: High-Performance Metal Bits for Precision Drilling by Justin Verslues

I have had several sheet metal cases that I had to drill holes in and install threaded inserts in and my drill bits were not sharp at all. When they became available I decided to order them and try them out. Here's what I found: 1. Finally a toolbox that works and keeps things in place! There is a double locking system that ensures the case stays closed when you really don't want it open.2. This is a well-ordered set of metrics that is, and will remain, accurate. After drilling 633 holes, the drill bits stayed sharp and performed exactly as advertised. There are no sizes missing! 3. All Threaded Inserts fit perfectly and snap into place as intended. This means the holes must be the same and the right size.4. As with any metal racquet, adjust the speed and keep the racquet cool. Heat is NOT your friend! Cutting oil is helpful. I am happy with the performance of these bits and would recommend them.
