Didn’t last a single use, broke on the first try, really bad product, I’m to late to return it, I wouldn’t recommend it, you got what you pay for.

Wow, for the price you get a lot with these bits.They are high speed steel and probably not going to last forever, but at these prices who cares? Brad point is appreciated making it easy to center up, and they work as advertised.Nice to have a number of size options.Four stars for value, quality is ok and I’d say great for the price.

I've used these bits on various wood types, and the results have been consistently excellent.Overall, I highly recommend this countersink drill bit set to anyone looking to enhance their woodworking toolkit.
