Slitting saws for small mill.

I've been looking at slitting saws to use on my Sherline mill.

For general work, the 50mm ones with a 13mm bore seem an appropriate size and quite widely available.

Can anyone recommend a supplier or brand? I am assume that all blades are not made equally and I have been caught out before buying cheap and then having to buy again.

I've got everything ready to make an arbour but I haven't used a slitting saw since 1982! Are there any hints or tips in their use?

I'll be using them in a range of thicknesses and materials so general info would be useful.

I assume that climb cutting is out of the question but apart from that, I'm in the dark.

Cheers, Steve

I tend to buy top quality brands, second hand on Ebay. I am lucky to have facilities so that I can sharpen them myself. Surprisingly most were excellent to reasonably sharp. Only a few have been blunt.

Recently I had to make a complex Church Door key and wanted the saws to be correct width. I never have any luck in trying to cut a larger slot than the width of the saw, using a couple of passes. So I purchased what I needed from Arc Eurotrade. The slitting saws were pretty damn good and the price was also good. I assume they come from China, but Ketan's QC always works for me and I have only ever had good stuff from Arc

The only other place I have tried was Tracy Tools, some were brand names, but heftily discounted.
