Does anyone know where I can find a 3 3/8, 24 tooth blade WITH A 5/8 BORE HOLE.
Every one I can find has 15MM hole.
Surely somebody sells such a bade with an imperial sized hole.
Actually, I suppose a 4” blade would work but, 3 3/8 would be best.
I’m planning to use it in a router table as a slitting saw for cutting box tops and creating corner slits for corner reinforcements.
Thanks, guys.

I think this one will work for you.

Give the company a call and verify the bore diameter. I believe it is a 5/8” bore.

Thanks John.
Unfortunately, the bore is 1/2”.

Gene, Would a slot cutter work for your situation?

Any saw shop can bore it out to 5/8”. Not costly. I’ve
had several European table saws that I had blades
modified to fit.

I’m concerned about rim speed, but I’ll assume you’ve
got that worked out.

Loren mentions an important factor, but I’m afraid he didn’t emphasize it enough for people who aren’t aware that regular saw blades are not made to turn at router speeds. Same with angle grinders. It is critical to have a blade, bit, wire wheel, grindstone, etc. with an RPM rating at least as high as the RPM of the tool it is being used on. Please be sure your blade is rated for the max router RPM.

Doc, I can’t get deep enough with my slot cutters. The cuts are also a bit wide. They work great for the corner spline cuts, though.

Loren, Up here in the boonies, the only machine shop around wants $40.00 to rebore the blade that only costs 10-15 bucks. I may have to resort to that but, it will hurt!

JimF, Many of the blades I’ve seen are rated for speeds of 10-14K. My PC 7518 can get down to 10K.

eddy, It’s still pretty cool up here. Come on up and I’ll show you. :-) Actually, the process is the same as using the TS. I will set the blade/fence (with a ZCI in the fence) to leave a sliver and cut it with a utility knife.
For the corner splines, I use a sled with a 45* fence/stop. I was thinking of using the slot cutter (1/8, 1/4 or 5/32) then inserting the spline, and finally, splitting the spline with the thinner slitting blade and inserting a contrasting spline.

Thanks for the replies, guys.
