Review on 🔩 High-Performance M35 Cobalt Drill Bit by Drill America by Jeremy Black

I have just received this set of 115 pieces. probably M35 5% cobalt index drill. I was disappointed to see that the #15 drill was missing from the kit. It seems that this set was put together from drills from different manufacturers and not from the same source, you can see different coatings and different marking processes in the picture. I don't mind much if they are close in quality. Pros: It's great value for money, other kits cost the same just for regular HSS. Although the drills look like they came from a different source, they appear to have the same cutting edge and feel sharp. Cons: Uneven finish on all drills. Missing drill #15 on arrival. The drill with the letter Y was covered in dirt and grime.
