These are fine, the ones I’ve used so far work great. Good value for the money I like the little case, it keeps the edges of the counter, sinks protected, so they’re not just banging around in a drawer.

works great

Honestly I was so focused on getting some countersink bits that when I looked over the description I completely overlooked the case they come in. I like the case.The drill bits themselves are decent quality, it's really the value of price to quantity that makes this worth it. I've used standard drill bits as countersinks before, but this is a nice step up so I don't have to be as careful about drilling my pilot hole diameter too large. Honestly, still have to be more careful with these compared to the countersink/drill-bit combo bits that do pilot hole and countersink at the same time. Still these will save me time and effort. It's a good value for the number of bits you get and the case is a nice to have.

Bought these to replace an old dull Vermont American one that only had one cutting edge and wobbled like crazy and made uneven off center bevel. These have five flutes so they don't wobble make a nicely centered counter sink.

No chatter. Flat head bolts fit perfectly into camfer cuts.

I like having the various sizes in the handy case. So far I've only used oe of the cutters it was sharp and cut a clean profile
