I broke the auger on my Powermatic chisel. I was looking for a replacement. I first bought the Delta chisel. Not only would it not fit my Powermatic mortiser but the outside of the chisel was poorly finished and rough. It would have taken a lot of time smoothing it. This chisel was cheaper and looked like it would fit my mortiser. I paid $17 for it on Amazon.. the chisel is smoother than the Delta. Very much like the Powermatic. Comparing it to the Powermatic the auger had fewer spirals. I don't know what the quality of the steel is. I sharpened and honed it and made a few mortises in maple. I took it slow only making partial plunges. It seemed to work fine. Not sure how long it will last but I'm keeping it.
Surprise for the hubby. He loved it. The smile on his face was radiant. I, honestly, didn't know what "mortising" meant. Haha. Was a great surprise. I surprised him with these and he surprised me with my Kindle FIre HD.
Got these to replace the Rikon Mortising Chisel set that came with the machine. These are much better.
Love these. They have made my projects much easier to complete. I will research if they have metric sizes and purchase those also.
