these work really well.

These are very high-quality mortise chisels. I used them with my Powermatic 719T mortiser to make mortises in Wenge. Historically, I had been doing those with a router and a chisel. Wenge is a pretty hard wood (and brittle). I was a bit skeptical about how well they would perform because of my past experience using a router and chisel. However, with these chisels, it made the mortises very easily. No smoke or anything. I was able to do mortises on wenge without effort.

It makes square holes and can be used to make rectangular channels in wood. I don't think any further explanation is required.

Very pleasantly surprised at the value of these chisels. They are better quality than a different brand that I originally purchased with the mortising machine. Be careful, though, some machines use 5/8ths shank bits. These are 3/4".

So far these have worked very well with my HF Mortise chisel press. They had a very poor sharpening from the factory. But after only a few minutes on each one I was able to greatly improve the edges substantially.

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.

Drill a square hole and less expensive than the other sites. I was expecting some cheap junk for the price, but it was really good.
