Its the most expensive hole saw notcher on the planet I think but has roller bearings instead of bushings and is beef! Works awsome and dosent deflect like some of the other notchers.
Very happy with it and I doubt Ill ever have to replace it.

That thing does look beefy, but man $$$$. I really havn't had a problem with deflection. I have used mine so much, you figure the best way to use it. As I said previously, use good hole saws. It also hlpe to use cutting oil. It is not required, but it will make your saws last longer. The only time I saw any deflection is when I was trying to get by with a dull saw. If you use a good saw and let it do the work instead of forcing it through you will have no problem. I think I am gooing to take a look at the needle bearings.
