Sigma 240

[Pie]

Talking about the sigma power select II (???) 240.

I’m still kinda yearning for more speed and less pain flattening for coarse work. SG220 too slow, cerax 320 melts, and SP120 too finicky without max pressure.

Outside of a manticore or something extreme, would the sigma scratch the itch?

Thanks in advance guys!

I have it. It definitely eats metal continuously. It is a softer, muddier stone. Definitely something you don't need to use high pressure with. I'd definitely recommend sealing it. It's pretty porous.

This is a good question. What is at the extreme end of cutting speed?

I bought the new Suehiro Gokumyo 240 recently wanting something faster than my Sigma 400 and it’s not faster. Much better edge quality so it’s a nice winner there but I was really looking for speed.
I bought a Naniwa Lobster 60 grit SiC years ago thinking it would cut like a monster. It’s super slow. Garbage stone. I still have it for some dumba$$ reason.
I also had a huge Naniwa 240 green brick. This was fast but it was VERY soft which I hate. Gave it away.

I’ve read the Sigma 240 is fast. I’m wondering what else is out there at the top of the cutting speed food chain. How does the DMT XX Coarse fit up there? Atoma 140? What else?

Diamond plates are fast. Have a tendency to leave deep scratches. And then wear out and cut slow.

What about Suehiro #180 or Sun Tiger 220?
