Flat bottom with a forstner bit - Woodworking Talk

Dvoigt · 12-18-2008, 08:58 AM

I'm using a forstner bit to achieve a flat bottom hole, however the tip of the bit creates a dimple in the center. What is the best way to clean that out? It is too tight to get at with a chisel or sand paper

Thanks!

You might try a "clean-out" bit on your router. They have a flat bottom and some have a bearing on the side to limit sideways travel.

I second that. Use a router bit and jig. In fact, if you use a jig, you won't need the forstner bit.

How about a router bit in a drill press?

I myself would probably do something stupid like have a secondary bit and grid off the tip. Drill half way down then change the bit over checking all my adjustments and make sure the pice is well clamped.

That's exactly what I'd do, Daryl. Goofy minds think alike I guess...

I'll triple that motion Brad, that was the first thought that crossed my mind.
