With slitting saw blades,l have some nice 4" and 60 tooth 6" dia blades that run very true but they are now so blunt it is hard work .Do you good people on here send them away to get them sharpened ?, l know that the smaller blades are not a bad price so would think it would be cheaper to buy new ones ,but my bigger ones l would like to keep.

I think Stephan Gotteswinter did a sharpening demo on utube. Likely others, too.

Yes did have a look on utube , they all seem to use a service grinder or fancy grinding set up ,am thinking that l will have to se if l can find a firm to sharpen them,or if there is anyone on here willing to do them at a fair price.

If you are a member of a Model Engineering Club, you may find someone who would be able and prepared to sharpen them for you.

Possibly, you stay and watch!

Whereabouts are you located?

When I was at work I arranged the regular sharpening of 300mm (when new) cold saw blades. We waited until we had more than 20 then sent them off. It worked out quite cheap per blade that way. They were done on a CNC sharpening machine because the previous system used before that, which pushed the blade around by means of a pawl ratcheting around the teeth, tended to produce eccentric blades after a few sharpenings. It seems to me that if you have a Dremel mounted on a CNC mill with a 4th axis you could easily sharpen these blades (with a suitable dust extraction set up). I might have a go and see how it works out

Well it looks like the rough price to sharpen slitting saw blades is from a couple of firms is between 50 pence and £1 per tooth ,then there is the vat etc ,so may well just run them in to the ground an mybe have a play to edge them up a bit ,l do not know what they are like but the ones made in china are not that dear and l se rdg do a 4" that seem decent money, but thanks for your advice.
