Review: Long-lasting and versatile - Hollowed out stones for pots and a large boulder for a birdbath. Chews through hard sandstone and even worked well on rhyolite (harder than granite.) Method involved parallel cutting with diamond wheel, knocking out remaining stone fins, and then finishing by shaping and smoothing with this disc. You can actually carve stone with this "flying saucer" profile. Highly recommended.
Review: Super produit efficace en meulage - Extraordinaire outil pour nettoyer ou rectifier le métal neuf ou soudé ou rouillé dans un temps record comparé à toute autre meule abrasive WOW ! Merci vous me faites gagner du temps à chaque usage !

### ⭐⭐⭐⭐⭐ Quick easy work on carbide teeth for forestry mulching head on excavator.
*by R***W on 26 April 2025*

Was hesitant for price but works great. Use this on carbide teeth for a forestry mulcher cutter head on my excavator. Regular grinding disc's wouldn't touch them. This takes mere seconds on each one. After a few uses its still holding up well. Highly recommended.
