Best countersink
Best countersink I have found. Outlasts every brand I have tried. Been working a lot with hickory and theses don't dull as quick. Not indestructible

Nice addition to my Countersink Drill Bits
Countersink Drill Bits are handy when you want to put something together quickly and not have the screws level with the wood surface. This Countersink Drill Bit from Bosch has worked well for me.

Solid choice
This countersink works well but I prefer the tapered style.

As advertised
Exactly what it was supposed to be.

Pilot bit comes loose
Did the job but only after having to continually retighten the pilot bit. Not a show stopper. Just had to have extra tools handy to retighten. Other than that, worked as expected.

It’s quite fragile
The drill bit snapped after drilling into soft white pine boards. Then the set screw stripped trying to secure a bit without the flat side. The results were good while it worked.

Wobbles
Like other reviewers, I find the bit wobbles , especially when the countersink part engages with the work.

Only issue I have is that the size does not match standard plug sizes. Other than that, no issues.

Sharp, easy to use, fits in my impact and drill. Broke after a short time while using in pressure treated lumber

Decent. Easy to adjust. It could be a little sharper.
