Sanding Discs Bosch X431 Standard for Metal, pack 10, MPN 2608603659

Bosch X431 Standard for Metal sanding discs are a 10-piece set designed for metal surface preparation and finishing. These discs use semi-friable aluminium oxide abrasive suited to removing rust, paint and burrs, smoothing weld seams and producing consistent finishes on coarse- and medium-sanded metal. The sturdy x-cloth backing provides stability during grinding, and the abrasive is bonded with fully synthetic resin to improve wear resistance during heavy-duty use. These hook-and-loop compatible discs are intended for use with angle grinders and orbital sanders that accept disc mounting.

Advantages

The aluminium oxide grain delivers robust cutting performance and consistent wear, helping maintain a uniform surface finish. The x-cloth backing increases dimensional stability and resists deformation under pressure for even material removal. Synthetic resin bonding improves longevity under high load, while the hook-and-loop attachment enables quick disc changes. The set of 10 provides spare discs for ongoing tasks or different stages of surface preparation.

Suitable for

• Removing rust and old paint from metal components
• Smoothing weld seams and grinding edges
• Deburring cut metal parts
• Surface preparation before priming, painting or coating

Key specifications

• Abrasive material: semi-friable aluminium oxide
• Backing: x-cloth reinforced backing for stability
• Bonding: fully synthetic resin for wear resistance
• Attachment: hook-and-loop (velcro) compatible
• Pack quantity: 10 sanding discs
• Intended substrates: ferrous and non-ferrous metals

How to use

Select a disc with an appropriate grit for the job and attach it securely to a compatible hook-and-loop backing pad on an angle grinder or orbital sander. Start grinding at low to moderate speed to establish control, using light, even pressure and moving the tool continuously to avoid creating grooves or overheating the workpiece. For weld seam blending, approach the seam at a shallow angle and progress with steady, overlapping passes until the desired surface uniformity is achieved. Replace discs when abrasive performance diminishes or when the backing shows significant wear.

Usage recommendations

Use appropriate personal protective equipment: safety goggles, gloves, hearing protection and a dust mask. Match disc grit to the task—coarser grit for rapid material removal, finer grit for smoothing and finishing. Avoid excessive pressure and prolonged stationary contact to prevent glazing, burning or distortion of the metal surface.
