Slitting saw info request

[ShawnR]

I am going to place an order soon with KBC for misc stuff. I found this thread... https://canadianhobbymetalworkers.com/threads/whats-on-your-tool-want-list.2252/#post-26582 which was interesting. Many of my wants are on it.

But one thing that I have had occasional want for is a slitting saw. There are some good videos about making an arbor for one (Blondiehacks, JoeP, others ) and it looks like a good project to work on my lathe skills. so I am just looking for a saw blade right now.

For a general purpose slitting saw, what is common/recommended?. I see holes from 3/8 up to over 1" The most common size on KBC is 1 " mounting hole. I picture 1/2" but wonder why it is less common. My need has probably been making collars or such, easily gotten around with a hacksaw or cutoff blade but the slitting saw is something I figure I should have at least one of. Any suggestions? Diameter? 3" ? Number of teeth? Mounting hole size? I am thinking HSS of course.... What width?

Mine are about 3”OD and 1”ID. Smaller OD might get you into tighter corners. Thickness depends on what you are using them for. The last two uses I’ve had were to put slots in screw heads so less that 1/16” thickness.

Thanks @Johnwa

I will order a 3" and see how it works out for me. Since the 1" id appears more common, ie, KBC has way more of them, I will order one of them. Speculation on my part right now but might as since I am ordering anyways.
