While the Woodworker I blade can be used on a radial arm/mitre saw, as Kevin stated, a ChopMaster is a better/safer blade to use because it has a -5º hook angle compared to the +5º hook angle on the Woodworker I. A blade with a positive hook angle tries to feed itself into the material...that's not good on a radial arm or mitre saw.
To your question, I have a brand new 10" ChopMaster Signature blade with a 5/8" bore that I wanted to have Forrest rebore to 30 mm to use on my Kapex, however they refused to do that. [sad] Their tech guy Tony recommended purchasing the 260mm ChopMaster Signature version for the Kapex instead.
Tony also said that Forrest will not sharpen any Festool saw blades. [sad]
They're getting kind of picky in their old age... [smile]
