Used 3 bits in hard wood. Works as expected.

Very happy with this set, I wanted to replace the 1-2 packs that the big box stores carry and these are way better. 5 teeth make for smooth cuts in the countersink and the multiple sizes are handy to have

Perfect for the money, cheaper than at the box store.

They do the work. Sometimes the second bit gets a little loose but damn does it do it's job.

Great product and great value. Quality was excellent. Very durable. I used them immediately upon delivery to predrill some holes for outdoor furniture I was working on. I drilled over 100 holes and no issues whatsoever. Can't say enough about them.

Works with my drill. Nice quality

Haven't used them long enough to tell about the durability or longevity.

Great quality, I've used then on metal and wood, no issues.

Excellent drilling, I did not notice any shortcomings.
