sorry, I apologize for that.

The tool you have

>I'm not quite sure why this current fashion for chamfering round dog holes - the "Popular Woodworking" chamfers, big enough to catch shavings much less sawdust, particularly bemuse me. The dog holes on my solid-core-door benchtop are unchamfered and seem to do fine.
But, if you would like to chamfer the dog holes on your bench, whatever tool you've got that will do the job should be fine. We're not talking furniture here.
If chamfer you must, then I recommend: *LINK*

>the single-flute countersink from Beall Tool Company. This leaves a crisp almost polished chamfer on holes to 1" and will do so in any 3/8" eggbeater. Not exactly cheap but you probably wouldn't wear it out anytime soon and it does what it does better than anything else I've found that's meat powered.

>I originally chamfered the holes to stop a problem with softwood tops � pulling the dog out would catch the grain and rip it out. The chamfers stopped that. If you're not having this problem, then there's no need to go the extra step.
There's no disadvantage to it. Dog holes catch shavings no matter what (unless you produce only fine sanding dust at your bench). There are some other small advantages, but I'm just gonna walk away from this one.

>After drilling holes in my maple top, the edges of those holes were sharp. Nicked knuckles several times before putting about a 1/32" chamfer on them. With a router. Doh!
my reason

>I have a hard maple top on my bench and I had no tearout problem.I just prefer the look of a small chamfer,and it takes a couple seconds with the right chamfering tool.Same reason I put a light chamfer all around the outside edges of the benchtop.---Jack

>Mine is a softwood top and I too was having some problems. When I would remove my brass dogs I would sometimes get some tearout as the grain lifted. I used a small chamfering bit in my plunge routah (didn't have a neander equivalent) and I am glad I did. No good reason not to do it IMHO.

I wouldn't

>I agree with several who have suggested that you dont need to do this. I have "softened" the arris with 100 grit and then 220 sand paper. It just eases the edge ever so slightly
