What Customers Are Saying
The drill bit set offers mixed performance. The bits are generally effective for drilling through wood and some lighter materials, but many customers reported the bits breaking or becoming dull quickly, especially the smaller sizes. The case has convenient organization features but does not securely hold the bits in place. This set may be suitable for occasional, light-duty use, but is not recommended for more demanding applications or frequent use.

Would Not RecommendI was very disappointed in these bits. They are not sharp enough to drill through oak or pine. Even the larger bits just throw out smoke. The are not a good investment.
Excellent drill bits that were on sale
Would RecommendExcellent drill bits that were on sale. Perfect for your DIY projects.

Broke 2 bits within seconds
Would Not RecommendAbsolutely useless. Drilling mild steel with little pressure, they didn't bite and 2 of the bits broke that were 1.4 thick, so no excuse. Stay far far far away from these, another terrible product from Kobalt.
Comically bad
Would Not RecommendThese bits are so bad it's actually funny. I seat them in a drill, spin them and think "oh, I didn't seat it correctly." But oh, no. The runout is that bad on every bit. It's almost like they were intentionally bent. add to that the worst designed case ever and I've dropped this mess in the trash.
Good price

Horrible
Would Not RecommendSo I've used these on metal exactly twice. Both times I was simply putting a hole in thin aluminum square tubing. The bit snapped both times even with relatively low pressure. I've had a small old crummy Ryobi set for 10 years and I've only had 1 bit break in that time. These Kobalt bits are the most brittle bits I've probably ever seen.
Other bits I haven't tried
Would RecommendMade a hole in my material. Worked once anyway

Would Not RecommendBrittle metal that broke on first use. It was being used in soft pine and not even metal. Now I have to go all the way back to the store to return what I thought was a good brand.
