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"
