Oh, and you get what you pay for, too. Push-in bits can easily cost $150, that was $20. So yeah, I saved money for it. The steel is really soft. Easy to blunt but also easy to sharpen which is a plus. I have a Powermatic Morticer and it doesn't fit the hubs as tightly as the Jet and Poermatic bits and understand they are from the same manufacturer. I also didn't feel like CMT wiped the chips. I heard that Lee Valley has a nice inexpensive thing that I'll try before investing a lot of money.
Pros
For chiseling and connecting with power and precision.
I am a hobby carpenter, but I make beautiful furniture. I have a very good jet slotter. I bought a set of 4 grizzly bits and used them. I decided to buy a much nicer chisel to build my new workbench.

I pulled it out and decided to try my old rusty set of grizzly chisels. 4 chisels for this price. And this is not a highβ¦
Pros
For use in any standard drill with slotter or slotter.
I bought various sizes of CMT plunge chisels for my slotting machine. The bits are finely machined and quite rough on the outside. I spend about 30 minutes per bit polishing the bit, but some of the machine marks were so deep I couldn't remove them. After polishing I also sharpened the chisel. The drill bit also had a lot of machine marks and I spent 15 minutes with each drill bit to remove the marks and trim off the cutting edges which are sticking out slightly from the edges of the drill bitβ¦
