Purpose and key benefit: Heavy-duty metal guard that restores and improves safety on angle grinders by containing sparks and stopping flying debris. Designed to reduce injury risk and protect both the operator and the tool during cutting, grinding, and polishing tasks. Compatibility and size: Fits angle grinders that use a maximum 5" (135mm / 5.31") grinding disc. Outer diameter 135mm / 5.31" with an inner mounting diameter of 42mm / 1.65". Use when your grinder accepts a 42mm arbor or the equivalent mounting. Durable construction: Made from solid metal iron with a compact structure that clamps securely in place. High hardness and good wear resistance deliver longer service life under regular workshop use. Easy to install and maintain: Designed for simple embedding and clamping on standard rotating tools. Grinder guards are one of the most commonly replaced power tool parts, so having a reliable, easy-to-fit replacement reduces downtime. Performance and protection: Installs on rotating tools to shield the operator from sparks, grinding debris, and the consequences of disc damage. Helps keep work areas cleaner by directing sparks away from the user and nearby materials. Versatile use: Suitable for a wide range of grinding tasks including cutting, grinding, and polishing. Can also serve as a protective cover for other compatible tools that require an outer guard. Typical applications 1) Metal fabrication: Use when cutting or grinding steel pipe and sheet to contain sparks and fragments and protect nearby components. 2) Welding cleanup: Install while removing weld slag or smoothing joints to protect your hands and body from flying particles. 3) Surface finishing: Fit during polishing or light grinding on metal surfaces to maintain safety without interfering with access to the workpiece. Specifications Maximum disc diameter: 5" (135mm / 5.31") Inner mounting diameter: 42mm / 1.65" Material: Solid metal iron This guard is a practical replacement part for keeping your angle grinder safe and compliant during everyday workshop tasks.
