 What do you folks think are the best, longest lasting non-sintered hard diamond grinding wheels? I had bough some from Cyber Rockhound a few years back and they are not cutting as fast as they used to. He no longer seems to be in business and I think there may be better wheels than he supplied out there. Also thoughts on textured wheels versus plain surface wheels. I presently have a textured 100 grit and plain 180 grit on my old Raytech 8" grinder. I do like the way the textured one cuts hard material.

Spend the money on the sintered wheel. I replace my 80 grit a year ago and I have no visable wear.
I was replacing the 80 grit wheel every year when the 220 wears out I will be more than willing to
Pay the price for sintered

I agree with Jhon.  You'll spend twice as much or more on regular wheels as you will with sintered ones over the long haul.  Using anything but sintered is a waste of money IMO.  Plus they save a lot of frustration with dull, slow-cutting wheels.

 I agree. Jade Carver wheels are  a bargain but they are not quite up to the quality of Diamond Pacific. 80 grit now seems to be  the rough grind standard.

I agree with the others that sintered wheels give both speed and longevity for the money.  Where I differ is brand.  Mine is a very old crystalite rig and they have been making them for years.  But mine is very old and I can't vouch for current quality.  Maybe someone will let us both know.

The only brand I've used is Neosint commercial grade, available through Kingsley-North.  I use the 60/80 for rough-cutting cabs and my only complaint is it's so aggressive it tends to chip on cab edges.  I'm planning to get  a 180 sintered for closer grinding and deep scratch removal as an intermediate to my 220 sintered for final shaping.  I cut a lot of cabs and would never go back to regular plated wheels of any brand.  It would interest me to hear input on other set-ups and sintered wheel brands.

Sintered wheels are far less costly than any plated wheel.  They cost more up front but last a MINIMUM of 20 times the time a plated wheel will cut.

Thanks guys!! I am not a large production cabber and the cost of the sintered is way high, but I'll take your advice and at least go for a 100 grit which gets the hardest workout.
