I want the HSS ones I can use they are less aggressive than carbide. Oval and rounded are what I’m looking for.
Scrapers or actual cutters? Most of the shielded cutter available such as Sorby, Woodcut are HSS and can be bought separatly from the maker. As to the scraper type you can make your own out of flat or sheet HSS. The most common source and for the most part it will be free is old or broken Cold Saw blades. Broken blades are generally thrown out thickness ranges from around 2-3mm thick and are readily cut with the 1mm 4" inch cut offgrinder wheels. Punching a hole in them can be a challenge, I have seen a lot of comments on how the 'drill a hole' in them. But you can use an arc welder with eamp set high and blow a hole A bit rough but it will do the job. I use a Plasma Arc. cuts like a knife through butter.I want the HSS ones I can use they are less aggressive than carbide. Oval and rounded are what I’m looking for.

Virtually all my scrapers are DIY from cold saw blades. The Dutch or German blades have the superior HSS, I shigh away from the Chinese, local USA blades are good. I just dont see many of them down in my part of the world.
