The box appears cheap & nasty. Difficult to open & close. I hope the drill bits will be better. Not sure I have much confidence.

good quality

Arrived on time and packaged well. Sturdy metal case included but hard to open and the plastic helper broke after several openings. Main issue was, the 7/32 drill bit broke within seconds of use. This after two other smaller bits in the same case had worked fine. Was not applying excessive force and had proper angle. Worse, the broken bit wedged itself into the hole, requiring a ton of extra work for removal. Given the typical use case for left-twist bits, I can't recommend this set.

I broke 2 oil pan bolts in the block of my old f150. What a big dummy! I bought these to drill them out. Once I'd gone through the different sizes, 1 of the broken bolts backed out onto the drill. The other I must have really done a number on because I wound up having to drill out larger & re-tap the threads. Anyway. Made a daunting task much simpler.

I use one bit of the set and it worked perfectly however the set was short one small bit. Other than that the set was very good and functionable great to have to back out small screws or screws or bolts better stuck or broken. Yes I highly recommend this set.
