- Wood River Single Flute Countersinks
- Brand: Wood River | Category: Drill-Driver Accessories

I had always heard that this style produces a very smooth cut, so I decided to pick some up when I was at Woodcraft. I bought the #6, #8, and #10. It really is amazing how smoothly and effortlessly they cut.
The second picture I uploaded shows just how smooth these things cut (#10 is shown, but the results are typical). On the far left is the Wood River single flute countersink, middle is one from HD (can’t remember the brand), and right is from a Ryobi countersink set. Lower board is poplar, upper is walnut. You can pretty clearly see that the single flute is the best, followed by the Ryobi, with the brand-less one in a distant third.
Gripes- I wish they had a 1/4” hex shank, simply for the incredible ease it offers
- If you try to drill too deep (ie counter sink then bore if you wanted to put a plug over the screw hole) the waste exit hole will drop below the work surface and it will clog
Score: 4 stars due to the clogging issue
5 stars otherwise

It looks like the hole does not go all the way to the point. Is it hard to use in hard wood. How about in a portable drill or a drill press. Any difference?

That’s a really good point Karson. Since the cutting edge does not go all the way to the tip you need to make sure that you drill the pilot hole first. If you don’t drill the hole first it won’t work (might be able to force it on the drill press, but why would you want to?). If there is a pilot hole it cut like a hot knife through butter with both the drill press and a cordless drill.

I just got a similar set from Lee Valley and I agree with Steve. These are by far the best countersinks I have ever used.

Wow, I wondered about these myself. It seems like there is now something else added to my shop list. (I’m sure my wife will thank you.) Thanks for the review.

It is a much better countersink. Certainly the best I’ve used. The HF star-shaped ones are terrible!

Isn’t it strange that the more cutting edges there are , the worse the hole is.?
I also wasted too much money on the “star” shaped multi-cutter countersinks in the past.
I’ve had great results with my Insty-Bit combination (drill and countersink) bits , and they’re 1/4” hex drive as well : )

I bought a set of these about a month ago after reading several positive reviews. I completely agree that they are the best countersinks I have used. I threw my old star type countersinks away after the first use of the new ones.
