Drilling a table saw blade

[noddy67]

I've a number of old table saw blades from a previous table saw that I need the bore increasing slightly and also need a small secondary hole drilled in them to fit on a table saw blade. Does anyone know of somewhere (preferably in Kent) that can do this or is it something I can just do on a drill press?

Thanks

I had a few drilled at work.
You need a length of bar the same size as the existing bore clamp it in the chuck and clamp the blade down replace the bar with the correct size drill and drill.
You need to have a drill press that will take the bar and drill but it is possible.
Most small engineering firms will be able to do this.

As Mr Maddex says, an engineer would be best and accurate.
If it's not spot on, just a couple of thou out, and only a few of the teeth will be cutting.

Had my dado set & a couple of saw blades centre holes enlarged from 5/8" to 30mm, the engineer did it on a Bridgeport milling machine.
