ONEGOTOOL 4-1/2-inch Tile Cutter Diamond Blade for Angle Grinder - Porcelain Ceramic Glass Marble Cutting Disc (10pcs)

Overview

The ONEGOTOOL 4-1/2-inch Tile Cutter Diamond Blade for Angle Grinder is built for precision work on porcelain, ceramic, glass, and marble. This blade is designed to pair with standard angle grinders for tile installation, backsplashes, and remodeling projects that seek clean, consistent cuts.

At the heart of the blade are fine-grained, high-intensity diamond particles that help produce smooth cuts and minimize chipping. The result can feel like a crisp edge along the tile surface, with less need for touch-up after the cut.

Designed for ease of use, the blade offers low cutting resistance, which can translate to steadier operation and less fatigue during longer sessions. The one-piece molded construction increases durability and safety, helping maintain dependable performance under demanding conditions.

The blade features dual-sided 30mm wide diamond sanded edges, enabling efficient grinding and polishing on both faces. In addition, the ultra-thin 0.05-inch kerf minimizes waste while preserving sharpness for narrow, precise cuts.
