Grinding Disc NORTON Starline 125 mm x 6.4 mm A24Q-BF27 for Metal, pack 25

NORTON Starline grinding discs, 125 mm diameter and 6.4 mm thickness with abrasive grade A24Q-BF27, are designed for metalworking tasks on angle grinders. Supplied in a pack of 25, these discs are intended for cutting, grinding and smoothing metal surfaces, welds and edges. The product combines a balanced abrasive grit and a reinforced bond to provide steady material removal and a predictable wear rate during use on steel and other ferrous metals.

Advantages

The discs offer consistent abrasive performance due to the A24Q grain specification and bonding system, which helps maintain cutting speed and surface finish throughout the disc life. Their 125 mm diameter and 6.4 mm thickness are compatible with common small-angle grinders, while the reinforced construction reduces vibration and risk of breakage under normal operating conditions. Packaged in quantities of 25, the set ensures ready supply for professional workshops and extended hobby use.

Suitable for

• Cutting and rough grinding of mild and medium-hard steels
• Removing weld beads and smoothing weld seams
• Deburring edges and shaping metal parts
• Workshop use for fabrication, repair and maintenance tasks

Key specifications

• Disc diameter: 125 mm
• Thickness: 6.4 mm
• Abrasive grade: A24Q-BF27
• Application: metal cutting and grinding
• Pack quantity: 25 discs
• Designed for use with handheld angle grinders

How to use

Mount the disc on a compatible 125 mm angle grinder following the tool manufacturer's instructions and ensuring the grinder is switched off and unplugged or battery removed during installation. Use appropriate flange and nut to secure the disc. Operate the grinder at the recommended maximum RPM for the disc, apply steady, even pressure, and move the disc across the workpiece without forcing. Allow the abrasive to do the cutting; excessive pressure shortens disc life and increases heat generation. Replace discs that show signs of cracks, severe wear, or imbalance.

Usage recommendations

Always wear suitable personal protective equipment including eye protection, hearing protection, gloves and respiratory protection when grinding metal. Ensure secure clamping of workpieces and maintain proper guard position on the angle grinder. Store discs flat in a dry environment away from extreme temperatures to preserve performance.
