I am looking for a small slitting saw, 1 1/4" x .082", anyone know where i might buy one ? I have looked on ebay etc, but this size is smaller than any i can find.

Is the 1 1/4” dimension diameter or arbor size?  2mm is close.

Try searching for Dremel 32mm saw blades, many available but perhaps not the exact thickness you want,
you may be able to double up 1mm thick blades for close to your desired width.

Yes 1 1/4" is the diameter of the blade itself, not the arbour hole. I will look at the dremel blades.

Chronos have 20mm 25mm and 40mm, if the thickness is critical perhaps a thicker one could be ground down.

Ronan,

CR Tools in Sheffield have several options very close to what you want.

I have no connected except as a satisfied customer.

What bore do you need? I can have a look in my box of slitting saws as I no longer use the very small ones (used to when I had a Myford), some are really small diameter and from memory I think most were about 1/4" bore.

CTC do a range of small slitting saws cheap enough for a punt. The arbor they provided was rubbish but that's easily knocked up.

Arbour size is not really important, as i can make up a simple one, its for a one off job.

Arntz **LINK**have a good metric range of small slitting saws, it is a German based compagny but curiously only the Dutch and the US agents have the small ones. The direct link does not work, you find it by; Circular Saw Blades - Metal Circular Saw Blades and then at the end of the page you go to DIN 1837-1838. The 2 mm thickness will probably make a slit around 0.02 mm wider. If you clamp two of 1 mm together it will be less accurate and very close to your desire and if you want it a little wider you can clamp a shim from 0.02 mm or more in between. Niko.

I have just been through my tin of small slitting saws.

I don't have an 982" one but have a pair of thinner ones that gang up to 087 if that is near enough for you.

The blades are 1.75 diameter with 5/8 bore. Both ares HSS one by Buck and Hickman, the other Wolferal.

Would these do the job?

Thanks for taking the time and trouble to do that John, but the OD needs to be 1.25", the thickness is not so critical, around the 2-3 mm mark, but the diameter is. Thanks again.

Ronan, what are you using the saws for?

Would it be possible to make a simple cutter from a slice of silver steel or piece of gauge plate with say 8 teeth that could easily be mounted on an arbor or what about grinding down a cheap 1 1/4" dia woodruff cutter to the required width?

Some on the big river. Probably not what you want or of decent quality, this set contains one cutter of 32mm diameter, but is cheap and blades could possibly be ganged together for extra width? Only posted it because we have no idea of the material to be cut...

There's this one I made from 1 1/4" silver steel. Ended up about 29.9mm diameter, 2.65mm thick.

I wanted to cut holding down slots in the sides of a cast iron toolmaker's vice. Did a great job and since I've used it for a few other things. Looks crap, but works fine, just needs to eb run gently as it's carbon steel.

You could copy it as Jason suggests, or if you are really stuck and it's near enough on diameter I could post it.

It is to mill a semi-circular slot into a block of steel about 8mm square. There is a piece that fits through the slot and when the 8mm piece lifts up and down, the cross piece, which is mounted on a pin, is used on the opposite end to lift something else, like a miniature see-saw. This is for a job for a college students project, i am not fully aware of what it does, and i would rather buy a cheap slitting saw than waste more time making yet another piece. Thanks all.

Is it not possible to make the cross piece fit the slot, that way the diameter of the saw is not critical. Niko.

The minimum order might make it a bit expensive? But, if needs must....

I made a personal visit and was made very welcome, pleased with my purchases as well. I have also purchased online and it all went smoothly.
