Abrasive sanding discs Bosch 150 mm C450 grit 40, pack 50, 15-hole (2608621730)

Bosch abrasive sanding discs, 150 mm diameter with C450 backing and P40 grit, are intended for medium-to-heavy material removal on wood, painted surfaces and metal. The pack contains 50 discs with a 15-hole pattern that fits orbital and random orbital sanders accepting 150 mm, 15-hole abrasive. The discs are designed to provide consistent cutting performance for paint stripping, leveling surfaces and preparing substrates for finishing.

Advantages

The C450 straight-backed construction ensures stability and even pressure distribution during sanding, reducing clogging and improving abrasive life on coarse work. P40 grit cuts aggressively for fast material removal while maintaining a predictable finish for subsequent finer sanding steps. The 15-hole pattern supports efficient dust extraction when used with compatible sanders, helping to keep the work area cleaner and prolong abrasive performance.

Suitable for

• Removal of old paint and varnish from wooden and metal surfaces
• Rapid stock removal and leveling of timber and composite materials
• Pre-sanding before filling, priming and repainting
• Sanding of metal surfaces to remove rust and scale before treatment
• Use with 150 mm orbital and random orbital sanders that accept 15-hole discs

Key specifications

• Disc diameter: 150 mm
• Backing type: C450 straight backing
• Abrasive grit: P40 (coarse)
• Hole pattern: 15-hole for dust extraction
• Pack quantity: 50 discs
• Compatible tool type: 150 mm orbital and random orbital sanders with 15-hole interface

How to use

Attach a disc to the sander according to the sander manufacturer's instructions, aligning the 15-hole pattern with the sander's dust extraction ports. Start sanding at low speed to establish contact, then increase speed as appropriate for the material and tool. Apply steady, even pressure and move the sander in overlapping passes to avoid gouging. Replace the disc when cutting efficiency drops or the abrasive becomes clogged.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, respiratory protection and hearing protection when sanding. For best results on painted surfaces, begin with P40 to remove coatings quickly, then progress to finer grits for finish preparation. Ensure compatible dust extraction is connected to improve visibility and extend disc life.
