Spring-Loaded Corner Chisel

Routing hinge mortises for butt hinges is a huge time saver, but squaring off the round edges of the mortise can be fussy work. That's where this corner chisel can really clean up shop. One quick chop, and the corner chisel cuts a neat ninety degree corner that is perfectly aligned with the hinge gain. The corner chisel is razor sharp and spring-loaded, so it immediately returns to a ready position for the next hinge corner. Simple and effective!


Features:

  • Square edges of housing automatically align corner chisel with hinge mortise
  • Spring loaded chisel returns to ready position for quick, efficient chopping
  • Cuts a neat ninety degree corner
  • Made from heavy-duty steel to withstand years of use

Terrific, small tool
I'm replacing all my interior hollow-core doors with solid wood, 6-panel doors. I bought door blanks to save money. I'm installing three square butt hinges on each door. I made a mortise jig to use with a palm router to cut the hinge and lock set mortises. Routing left rounded corners on the hinge mortises. Squaring the corners with a hammer and chisel was tedious work. The spring-loaded corner chisel makes clean, square corners in seconds. It saves a ton of time, and the result is a perfect corner. It's certainly worth the money.

Great Little tool
Needed to replace some older rounded corner hinges. The new ones only came with squared off corners. This tool did the job. Couple of taps with the hammer and then using my chisel to remove the rounded part. worked great. New hinges dropped right in!!!!

I started making specialty boxes and...
I started making specialty boxes and use a lot of stop dadoes and stop rabbits on the router table. I use this corner chisel to square up the ends where the router bit leaves it round. It works very well up to about a half inch deep. On deeper ones I sometimes have to go easy and do it a little at a time but it still gives me a clean, square cut, right out of the box.

I was going for a deep rabbit (3/8") and it worked well in basswood. Might be a bit trickier in say black walnut.

I like square corners on my hinge pockets. My 90 degree chisel is too small to make a large enough clean cut. So I'm going to try this. i've seen them several times, and now is the time to buy.

I'm replacing all my interior doors and will be cutting hinge mortises in 13 doors (3 hinges per door). I'll use a trim router to cut the mortises, and this corner chisel will make it much easier to square the rounded corners.

Will this work on regular size hinges?
Matin H on Jul 12, 2016
BEST ANSWER: This chisel simply squares the corner of the mortise so it will work with any size hinge that requires square corners. It does not actually cut a hinge mortise. it just provides a quick way to square up the corners after you have cut them with a router and mortising template.
Is there a round corner chisel for recessing the striker plate into the edge of a door?
steve j on Mar 13, 2016
BEST ANSWER: I don't imagine such a tool would be necessary, as a properly mortised door (hinges, strike plate, and latch plate) is done with a router and some sort of jig, leaving all corners rounded. The corner chisel is just used to square the corners off in the event square hinges and/or plates are to be used.
However, if you did for some reason need to re-mortise a round plate and did not have access to a router, a spade bit of the desired diameter could be used to "freehand" the radiused corners.
Hope this helps,
Casey
