ATLINCorner Chisel - Square Mortise Chisel for Hinge Mortises, Door Installation, Framing, Woodworking

Works great for hand mortising door hardware

where is good on hinges and lock bolts?

Works well enough, but it's pretty bulky. It's not going to square out things like slots.

Easy to use, makes really nice corners, decent price for a hobby woodworker

The crisp corners make the job look professional.

Works good quicker than than chiseling one side at a time

I needed a corner chisel for a night table that I was making. I made a template for the drawer opening out of MDF. I drilled holes in the four corners of the workpiece and used a jig saw to cut out most of the waste. I then attached the template with double sided tape and used my router to finish cutting the opening. At that point, I had to square the four corners. The ATLIN Corner Chisel worked better than I had expected. It lined up perfectly, I used it on both sides of the 3/4" panel and chiseled out the rest. Couldn't be happier with the result. Having only used it once I can't speak to its durability but I do like that it can be taken apart to sharpen the blade when it gets dull.

Perfect for cutting in corners after using a router.
