Freud BL71MCE9 1" OD x 5/8" id Saw Blade Arbor Bushing

I was weary because I wondered if it would be unstable, but it's a tight fit and worked great with a 12" Dewalt blade. No worries.

I just bought 6 of these bushings to recycle a 1" arbor dado set I have from a previous saw for use on my new Delta table saw. I was skeptical about stacking these things, but they worked great! The dado ran true and round with no wobble or vibration. The only problem I had with these bushings was that the fit is rather tight. I needed to tap them into the 1" hole on the dado blades, then "work" them on to the saw arbor. Once they were on the arbor, the center hole loosened enough for easy blade removal, except for 1 bushing that was still a little too tight. I guess a tight fit is better than a loose one for something like this, so I believe they will be fine. Once the bushings were on the blades, they remained in place. To remove them I had to place the blade on a block with a space under it, and tap the bushing. My summary is that they do exactly what they say they will do, adapt a 1" saw blade to a 5/8" arbor without any performance loss.
