Make you own from an old spade bit.
Just grind or file the profile you want. Many C-sinks are 82-Degrees includes. Aircraft c-sinks are 100-Deg.

i know its for cabinet connecting screws but maybe one of the sizes are right for what you need?
Thanks Grant, I break a lot of pilot bits.
Any day I wake up is a good day.
Jeff, Black and Decker made a 5 pc. Countersink and Screw Pilot Assortment many years ago that is a flat countersink with a round shaft that gets chucked in the drill. Model # U1588. They were about 2" long overall. I know this because I have had this set sitting in my drill bit drawer for probably 25 years. I keep looking at it when I open that drawer and just don't know why I don't throw it out since it looks so cheap and useless that I haven't ever used it. BTW, what was so special about a flat countersink. If you want a really good countersink and pilot drill setup, buy a set made by W.L. Fuller. Woodcraft carries them.
I have had this old set from Craftsman for more than 30 years. The stop is long gone, the spring metal clip that gave you 3 different depths of CS, broke and I can't find it any more. Half the bits are lost and most have been sharpened numerous times. I doubt these are available any more.
I think Joe found them. My monitor pic is not so great, but that sure looks like right ones.
Thanks for the find.
It doesn't appear so. I looked on Sears site for these yesterday with no luck. I've got the same set except mine is in a plastic pouch with dividers for each bit. A couple of the bits either got lost or had the tip snap off but I do still have the stop collar. I dont find the collar all that useful though as I normally just put them in the DP and control the depth with the DP. It is nice for cordless drill use though. Dont know why they stopped selling those. They work pretty good.Originally Posted by Dik Harrison

I still have a few that I use occasionally. I think I got a set from Sears many (20-25?) years ago. They raise some fuzz around the edge of the cut, but other wise work fine.
Jules, Joe, and others -
I am looking for a set of these. Apparently no longer available from Black and Decker. If you have any you are not using - especially the #8-10 size - I would like to buy them. They work well enough for me on soft woods, osb, and plywood.
Thank you.

If you were good with a grinder you could resharpen a Kreg step drill bit to countersink. I might try it with one of my dull bits.
Believe it or not, they cut clean holes in acrylic plastic without blowing out the back like a twist bit. Got mine at Sears in the 70`s.

Thank you for the reply. I'm hoping one of you guys wants to get rid of their old Black and Decker bits before I modify something to work instead.
