Squaring off a router plunge cut

Hi All,

I am working on a project and need to have a square cut in the middle of wood rather than a rounded edge halfmoon cut (see picture). Is there a router bit that would allow me to do this?

Basically I want the end of this router cut to be square and not circular.

Thanks so much!

Use a sharp chisel. Nothing that rotates in a circular motion can make a square end to the groove.

You can use a squaring chisel. Imagine a chisel with an "L" shaped end instead of flat.

You hammer the chisel down and lever out the waste. Regular (thin) chisels can be used if you take small cuts. The final blows are a light cut with the bevel facing the slot that leaves a square end without crushing the wood fibers on the shoulder.

If that's the mortise end of a hidden joint, many builders find it easier to trim or sand the tenon round to match--rather than try to chisel the corners of the mortise.

The tool Ray shows is great for shallow mortises like locksets, hinges and door strike plates.
