82 Degree Countersink - great for dog holes No-picture-s No-picture-s Click the pictures to enlarge them

Just an FYI:

I needed to chamfer all the dog holes and the parallel guide holes on my bench. I have a cheap countersink from Lowe’s for the parallel guide holes but it sucks. Talk about chatter. At the end the holes look more like ten point stars.

I thought about a round over bit in the trim router but I still need a good countersink. Then I saw this in the Lee Valley catalogue. It even mentions dog holes. Free shipping and it was a deal.

Smooth! No chatter. No tear out. No dust, ear plugs or extension cords. So I introduced the new countersink to my ole Fray Spofford brace and I am good to go.

This is the crappy one from Lowe’s

—————————————————————————————————————————————————————————————————

——-Just something to keep in mind for those doing bench builds and it leaves you with a high quality, versatile countersink that works in any sized hole up to 1 1/4”.

I read somewhere that single flute countersinks are better for wood and multi-flute countersinks are better for metal.

Those sure are some pretty closeups.

One of the lead carpenters in our crating department shared this technique with me, which helps prevent chatter….

1. center puch hole
2. counter sink into the soliid wood first.
3. then drill the hole second

I have the one from Lowes. It does indeed suck. Thanks for pointing me toward a good alternative.

You can see the difference in the grind marks on the Lowe’s tool vs the Lee Valley tool. Good photos.

Thanks for posting… I should add one to my tool set… And, I like your idea of using the brace vs a drill… well done.

I have made some ten pt stars w/the ones I have, figured it was user error. Being lazy and not looking, was it spendy?

Yep, I learned the hard way that the single flutes are the only way to go in wood. I get mine from Wholesale Tool. Good quality and VERY inexpensive.

Single-flute = smooth
Multi-flute = fast

It really doesn’t matter the material. Multi-flute stuff usually chatters and leaves rough marks in metal as well.

Thanks for all the info. I just never really considered the nuances of countersink design. Go figure.
