Need a reliable disc for grinding down metal? This Faithfull depressed centre grinding disc is a solid, no-nonsense choice for your workshop. It's specifically designed for use with angle grinders (and only angle grinders, please don't use it on other tools) for stock removal on both ferrous and non-ferrous metals. The size is standard and super common: 115mm in diameter, with a 6mm thickness and a 22mm centre hole. The 'depressed centre' design is key – it means the centre of the disc is recessed, which gives you a better grinding surface and more clearance. For the most efficient results and the best performance, you should present the disc to your workpiece at about a 45-degree angle. Just a super important safety reminder: when you're using abrasive discs like this one, always, always pay close attention to the safety regulations. That means wearing proper eye protection (safety goggles or a face shield are a must), gloves, and hearing protection. Make sure your grinder's guard is properly attached and you're working in a secure manner. This is a straightforward, professional-quality consumable that gets the job done. Keep a few of these on hand for your metalworking projects.
