Hi there,

Anyone know where I might get a .280 or 7/25 flat tip router bit, 1/4 shank? Having one made is going to be too expensive….

Huh. Any chance you can share with us what you’re trying to cut and why, and maybe there’s another way to approach the problem? And how accurate does the fit have to be? .280 inches is 7.1, could that be a 7mm bit (as in a Festool 490956)?

It’s for 1911 .45 grips, the outer counterbore for the screw head. .280 fits nice and snug. I ordered a 9/32 which would be .28125 we’ll see how it goes, if the hole is too big, the grips move a little.

So the very slight undersizing of a 7mm bit might work then. You might find someone with a 7mm drill bit to test this.
