Fibre Sanding Discs | 125mm 8-Hole | Metal Grinding & Polish

These 125mm 5 inch 8 holes yellow sandpaper discs sand fast and well. They are not stiff fiber discs for heavy grinding. They are flexible. They work with orbital sanders to make wood, metal, and automotive primers smooth. Features and Benefits - Anti-Clog Stearate Coating - This special coating on the yellow sanding discs stops resin and dust from building up. This helps prevent clogging when sanding paint or softwoods. - Aluminum Oxide Abrasive - This is a tough, long-lasting grain. It works well as a woodworking abrasive disc. It also preps metal surfaces. - 8-Hole Pattern - The holes line up with most 5-inch orbital sanders. Dust gets pulled away from the surface. This makes your workspace cleaner and the finish better. - Hook and Loop Backing - These hook and loop sanding pads attach quickly and securely. It's easy to switch between different grits. Applications - Automotive Bodywork - These car sanding discs are good for dry sanding body filler, primer, and old paint layers. Use them before applying new paint. - Woodworking Projects - Use these 5 inch orbital sander discs for smoothing raw wood, rounding edges, and getting surfaces ready for stain or sealant. - Metal Preparation - This is a good choice for scuffing metal. It helps paint stick better. It also removes light rust and corrosion before painting. Step 1: Mount the Sanding Disc to the Mandrel These 125mm Fibre Sanding Discs require a suitable mandrel for attachment. The backing pad of the disc, while not explicitly hook and loop for this product, is designed for secure mounting. Ensure the mandrel is compatible with 125mm discs and the 8-hole pattern for optimal dust extraction if your tool supports it. Proper mounting prevents wobble and ensures even sanding. Option A: Standard Screw Mandrel (402) To use a standard screw mandrel, align the 8 holes of the 125mm Fibre Sanding Disc with the backing pad. Screw the disc securely onto the mandrel. Hand-tighten until firm, but avoid over-tightening which could damage the disc. This method is common for various rotary tools. Option B: EZ Lock Mandrel (EZ402) For an EZ Lock mandrel, simply push the 125mm Fibre Sanding Disc onto the mandrel until it clicks into place. The EZ Lock system provides a quick and secure attachment, allowing for fast disc changes. Ensure the 8-hole pattern aligns with any corresponding features on the mandrel or backing pad for balanced operation. Step 2: Insert the Mandrel into Your Dremel Once the 125mm Fibre Sanding Disc is securely mounted on the mandrel, insert the mandrel shank into your Dremel rotary tool's collet. Tighten the collet nut firmly with the collet wrench to prevent the mandrel from slipping during operation. Ensure the disc is centred and spins true. Always check the Dremel's maximum RPM rating and ensure it is suitable for sanding applications. Step 3: Best Practices for Sanding When using these 125mm Fibre Sanding Discs for car, woodworking, or metal applications, maintain a consistent, light pressure. Move the tool steadily across the surface to avoid swirl marks and uneven removal. The lifespan of a sanding disc varies greatly depending on the material, pressure, and grit used. For aggressive material removal, start with a coarser grit and progress to finer grits for a smoother finish. Use appropriate safety gear.
