The Comec RTV612 is a heavy-duty grinder designed for resurfacing flywheels, clutch pressure plates, and similar circular components — with enough power to handle industrial-vehicle flywheels and large clutch plates.
Because it offers a large grinding capacity and robust construction, RTV612 is ideal for shops or rebuilders looking to offer professional-grade flywheel and clutch resurfacing, or wanting flexibility to grind discs, rings, flanges or other circular stock beyond just automotive parts.
Additionally, RTV612 ships as a ready-to-use solution: the standard package includes coolant system with pump and settling tank, wheel-dressing tools, centering cones & rings, safety/splash guard, and all necessary fixtures for typical flywheel/clutch work.

Decades before today’s engine shops trusted our equipment, Tony was already deep in the craft — rebuilding motors, machining blocks, and pushing for better precision.
A local newspaper once featured him as a standout young machinist, noting his drive, attention to detail, and obsession with doing things the right way. That same passion would eventually shape our company’s values.
Today, that commitment lives on in every machine we sell, every customer we support, and every shop we help succeed.
