LINER 4.5"-5" Cutting Guard – Precision Tile Edge Finishing for Angle Grinders

Product Overview

The Mechanic LINER 4.5"–5" Cutting Guard is a precision finishing attachment designed to deliver straight, smooth, and dust-controlled tile edges. Engineered to transform a standard angle grinder into a guided edge-finishing system, the LINER improves accuracy, repeatability, and operator comfort.

Integrated guide rails ensure consistent straight-line grinding, while the fixture transfers the grinder’s weight onto the stop mechanism—reducing hand strain and fatigue during large projects. An integrated vacuum nozzle captures dust at the source, helping maintain a cleaner and safer workspace.
