Mean Green Dressing Stone – Aluminum Oxide
Mean Green Dressing Stone – Aluminum Oxide
The RTC Mean Green Dressing Stone is an aluminum oxide dressing stone for reopening glazed diamond blades, core bits, hole saws and grinding wheels.
RTC sells this stone on abrasive concentration, describing it as carrying the highest concentration of aluminum oxide available today. Dressing works by abrading the bond so fresh diamond is exposed at the cutting surface — a blade that has stopped cutting on dense material is usually glazed rather than worn out.
Key Features
- Aluminum oxide abrasive, at what RTC publishes as its highest concentration
- Reopens glazed diamond blades, core bits, hole saws and grinding wheels
- Restores cutting speed on tooling that has loaded up rather than worn out
- Sibling stone in the same line, Rockin' Red, uses a shatter-resistant rubber bond instead
Who Is This For?
Fabricators and tile setters whose diamond tooling has glazed over on dense porcelain, engineered stone or hard granite and has stopped cutting at its usual rate.
Frequently Asked Questions
What does dressing a diamond blade actually do?
It abrades away the bond matrix holding the diamond, exposing fresh sharp diamond at the cutting surface. It restores a tool that has glazed or loaded; it cannot add diamond back to a tool that is genuinely worn out.
What is the difference between the Mean Green and Rockin' Red stones?
RTC sells the difference on bond, not grit. Mean Green is sold on raw aluminum oxide concentration; Rockin' Red is a shatter-resistant rubber-bond stone reformulated with more alumina, which is the one to choose if stones get dropped on site.
My CNC process sheet specifies a dressing grit — can I use this?
RTC publishes no grit for its dressing stones, so where a process sheet calls for a specific grit you need a dressing stick that states one, such as the 150 Grit Aluminum Oxide CNC Dressing Stick.
Is this the right tool for truing a bench grinding wheel?
Dressing opens a glazed surface; truing cuts a wheel back to round and square. For truing a bench or pedestal wheel, a Huntington-type wheel dresser such as the Desmond No. 0 is the correct tool.
