The aggressive bite of carbide teeth against dense hardwood is unlike anything you experience with standard sanding discs. This Arbortech TURBOPlane transforms a basic angle grinder into a high-performance sculpting tool that handles everything from leveling large, flat surfaces to executing delicate, shallow cuts for fine detail work. I found the versatility particularly impressive. You can transition from broad planing to intricate shaping with ease. Because it uses high-class carbide edges, it doesn't bog down even when you're working through the toughest timber. It fits most standard 100mm or 115mm grinders, and the included spacer washer is a vital addition for dialing in the perfect cutting depth.
