Deburring / Chamfering / Countersinking Holes

[DieselDennis]

What tool does everyone use to knock the edges off of a hole in wood?  

I think for a general knock the corner off kind of clean up, I'd want a sanding cone.  But I'm having trouble identifying the ones I'm looking for.  I recall a rubber cone "tip" with a sandpaper cone that was probably at a true 45 deg angle.

What if you go a little deeper?  Like for a true countersink for a flat head screw?  What type of countersink works best in wood?  I have a little five flute jobber used in metalwork.  It's not bad to knock an edge off if you run it in reverse.  

Hole size could be anything up to say 5/8".

Pricey, but it's wonderful.

Long ago, from one of the mail order woodworking tool outfits, I bought a special, single fluted countersink for wood. IIRC it is about 1-1/4" dia, with a plain shank for chucking in a drill motor. Creates a perfect edge break with no chattering.

I like the KEO brand. They are a little pricey, but after you use one you'll see why.
Here's one on Amazon Countersink

These are similar to wood-chips' suggestion. They're the best I've found up to 1/2".

Anything larger, I use this:

That is exactly like the one I have.

I use an old brace taper bit in a hand brace. Not much money and I like the control. Much easier to control the depth and consistent between holes, by counting the cranks on the brace.

I have a ton of countersinks, but the one I always reach for is the kind with the single hole as the cutting edge...whether its wood or metal, it always gives excellent results......

I just got some of these pilotless ones in stock.  If you email me your feedback I send you one at no charge.

Let me know what size, right now I only have the ones referenced by screw size.

I've had a Weldon set for probably 25 years, similar to This One , except my set of four doesn't have the largest size countersink pictured. Works great on both wood and metal, doesn't chatter and leaves a very smooth edge.
