Is the SB-250 black stone a good choice for all-purpose ?

T8 with sg250 is on its way..  
I'll add a DF 250 later on! Thanks all for advices.

Awesome! I ordered my T8 yesterday! Many happy years of sharpening ahead!

I have my T8 coming. Not using it as a business but for personal use mainly for knife sharpening, which will expand with the Tormek to include planers and axes plus mower blades.
But I am not new to sharpening as I have been using my "Edge Pro" professional version for over 10 years now.
Getting to the point....One of the reasons I chose the T8 was to help, regarding more rapid material removal, as my extended family and anybody that has asked me to sharpen their knifes, brought knifes that didn't just require sharpening but total rebuild of the blade edges.
So I am going to add a 250mm CBN 80# Grid as soon as possible.
I am hoping that it can be used to remove material quick and re-build the edge shape first, before continuing with another stone for sharpening and honing.

Have you decided which one?

I'm using a lot of old pieces of wood, and my tools often meets an hidden nail.[...] it's a pain in the ass to spend 20 minutes on one chisel to get a straight edge when it could take 30 sec on a dry grinder.

I'd like to have only one stone.

Sorry about the late response. I suppose by now you've chosen a stone. I would recommend the SG as it will be more versatile. I would also recommend keeping your dry grinder handy. I use mine often to remove lots of steel when necessary, such as when you you have a large gouge in a chisel, dipping the tool in water often to keep it cool. Then finish up on the Tormek.

Just as an example, when sharpening a mower blade I first clean it with a wire brush attachment on my dry grinder. Then I start to grind on the Tormek so I can observe the edge and see where large amounts of steel need to be removed. Then I move to the dry grinder to remove lots of steel. Then it's back to the Tormek to again observe the edge. I repeat this as many times as needed. It speeds up the process and saves wear on the expensive Tormek grindstone. Plus, the water from the Tormek keeps the blade cool.

My Tormek sits next to my dry grinder so it's easy for me to switch back and forth.

My apologies
I just noticed this question now.
No, I haven't. The Aussie guy that used to sell CBN wheels appears to be shut down. I finally got my T8 and I am impressed with the original SG-250 Wheel that comes with it. Despite this, it just confirmed that a fairly "coarse" CBN wheel would be of benefit for re-shaping knife/tool bevel edges.
I prefer "Wet" CBN/Diamond wheels as I don't want any airborne dust in the room where I use the equipment, due to my Solar Inverters being located in this room.

I suspect any CBN wheel can be used wet, preferably with aan anti corrosion agent such as Hone Rite Gold or Tormek ACC. One of the CBN vendors I emailed several years ago insisted that his wheels must be used dry or the warranty was voided. I thought the numerous warranty claims he received were from careless users who left their wheels soaking. I do not believe there would be any problem if the wheels were left to dry when not being used.

I agree with you. I would not use CBN wheels dry. I use mine wet with Hone Rite Gold. If you can not get Hone Rite Gold in Australia, Use Tormek ACC.
