Corner chisel
Had one long ago but misplaced it. I had been working with just a smal hand chisel. I got this and remembered why I liked it so much. It makes corner clean up so much easier and faster!

Excellent tool
Good tool, good value. Does just what it is supposed to. Used to make square hinge mortises. Sharpening may be tricky, but probably won't need it for a while.

I'm looking for something to cut my chisel time on a screen door project. I picked this because it was highly rated and not Bluetooth compatible, laser-guided or wi-fi enabled and it won't talk to me. Simple. I like simple.

What are it's dimensions?
Crowing rooster on Dec 23, 2015
BEST ANSWER: The actual spring blade that comes out is 3/8 square and the whole unit that you see in the picture has a footprint of an inch square with a small edge that rides the corner that you are cutting out.
Does this Corner Mortising Chisel create a curved corner or a 90 degree corner? I'm looking for one that creates a rounded corner for door latch plates.
Sichuan on Dec 21, 2015
BEST ANSWER: This chisel cuts a hard 90 degree corner. We bought several for exactly the opposite problem; had to set square cornered hinges and our routed mortises naturally had a rounded corner. If you need a radiused corner for your hinges and a standard hinge mortising jig won't work the best alternative is to make your own jig and use a router.
What is the MAXIMUM cutting depth?
mountainman on Dec 21, 2016
BEST ANSWER: I believe it's 1/8"
