I am a tool and die maker. Been using Sunex tools for 8 years now. I am happy with them.Got this set to go with my new Dewalt impact. As expected, quality is good and support will be good.I did have an issue with the 1/4 size bit. The 1/4 is slightly oversizes and would not fit in the screw/bolt. I had to polish the coating off to try and fit it. Still, without the coating was oversized. I kept polishing the tip of the bit till I reached the proper size. We are talking about 0.002 to 0.003. Tiny numbers but when it comes to steel and fittings it makes a difference. Two of my co workers have same Sunex set. One had same issue as me and the other one did not.
