Chamfering holes in wood

[Paul]

What is a good tool to use in a drill press for chamfering holes, something that won't grab or chatter?

[Larry W]

Coutersink bits are generally available in common size ranges for various angles. Here's some cheap ones that may work for you.

name brands and other cheap ones are available from Amazon and the other usual sources.

How big of a hole (round or some other shape)? What's the material? Router, Spokeshave, Dremel-tool? Of course, you mentioned DP. I'm just the group-student around here. Surely someone who really knows will help, but I think it will be helpful if you will answer the first two questions.

The 93342 one above is pure crap. It chatters like a woodpecker. This one is good.

Bill... Reread the heading......WOOD ww

[Bill]

Maple or pine??? Both "WOOD", no? : ) lol

At the same time, when I first asked, "What's the material", I was wondering how "thick" the material present was--wanting to let one end of a spokeshave into the hole if possible. Sorry if I was vague.

I've had good luck with a countersink from Lee Valley in an old eggbeater hand drill. If I've got more than a dozen or so, the same bit works in my drill press. See:

I haven't tried the first ones, but the second sucks.

[Steve Turner]

Agreed. It's like they forgot to sharpen it or something...

The didn't forget. They just don't. :-)

---------------------------------- Save yourself the time and aggravation, forget HF.

Good cutting tools are not sold at HF.

Try WW Grainger, McMaster-Carr or equal.

Expect to pay about $15 for a decent counter sink.

Have fun.

45 degree chamfer? Router with a chamfer bit will give you the cleanest surface. Not sure I've ever seen a countersink for a 1" pilot hole, but a good one won't be cheap.

[Father Haskell]

For reamer type tools, those with odd numbers of flutes cut rounder holes.

Well, you could try a small piloted roundover bit (but in a router for best results, 'cuz the depth control is better). For big holes, maybe freehand with a rotary sanding drum like in a Dremel tool.

[Larry W]

"Good" is relative and you have to watch what you get from the industrial suppliers, too. Grainger, M-C, and MSC all have low cost import lines that in some cases are identical to the items sold at HF.
