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.

Exactly what it was supposed to be.

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

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.

Not work for #8 on hardwood
It does not work for #8 screw. Maybe Too small hole . I use on hardwood, it might work on softwood ..

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.
