I have picked up a few countersinks from The Home Depot, Valu Home Center, etc. They are really terrible. They chatter in the hole and produce ragged six or eight sided “stars” with corners and facets instead of a clean, perfectly conical hole.

I do have one I bought online, from Lee Valley here: http://www.leevalley.com/US/hardware/page.aspx?p=41012&cat=3,41306,41328 but it costs $24.50. It heats up rather quickly and there’s only one size, but so far, it has worked perfectly for me.

Has anyone found any others, perhaps in a greater variety of sizes that work well?

Cheers,

George

At what rpm are you operating them?

I know you’re looking for a dedicated countersink but I use these Dewalt drill/countersink bits and like them considerably.

Wood doesn’t particularly countersink well due to
the fibers and density variations.

I haven’t tried the new style ones but they look like
they would work well.

Sometimes if I need to countersink for a specific screw
type I’ll take a drill bit and regrind it to a steeper angle
to use as a countersink.

I have a set of Robinson ones you can have … please take them as they are junk too!

I do have some single flute countersinks that work real nice but you can’t have them!

I have the LV one you linked,it’s the only one I use ,if you can set your drill press to 250 RPM,you will get it to work properly.
I some times use it with a variable cordless drill .press and lift 2-3 times for each hole,it should be alright.

I buy the single flute countersink bits from Wholesale Tool and have been very pleased with all of them. Very clean cuts in all the woods I have used them in.

After seeing all these countersinks bits I have always a router bit and my drill run’s about 1350 rpm’s and I have used it on everything from Oak to Plexiglass and I just add Kobolt to my countersink bits and it has a 100 drawer’s under its blet.

I usually have much better results drilling the countersink first then the hole whenever possible, that is when I remember. In an existing hole a small portion of the flute is unsupported and causes a little vibration. Just my thoughts.

This one works really well. Similar in design to the Weldon linked above They make it both a 16mm and a 20mm.

Mike, I use the snappy countersinks that are like the dewalts. Made in the usa and they work great.
