Saw Arbors

[chan42]

I normally use the 5/8" bore saw arbor so I can use non-SS blades (Timberwolf, etc). Most reputable saw blade makers will bore the 1 1/4" for the SS "native" saw arbor.

My question is what is the gain/loss for using the SS bore over the universal 5/8" bore?

The 5/8" bore, with its small nut and washer doesn't support the blade very well, so many woodworkers use stiffners on the blade. The 1 1/4" arbor grips the blade further from the center and acts as a stiffner.

This becomes even more important when you use thin kerf blades.

good point. I use stiffeners anyway. tkx
