Tooling-Slitter advice

[TomG]

Greg,

You can make a better slitting saw arbor than you can buy. The style shown in the pic is easy to make and allows you to get very close to a ledge on a part without interfering. This type doesn't use a key and in fact, you should never use a key for a slitting saw anyway because it will shear under load. The keyed ones you see with the 1" shank are for wider cutters or gangs of cutters.
