Product Information
Full details
The Bosch X451 Flap Disc is an essential abrasive tool designed for metalworkers, renovators, and dedicated DIY enthusiasts who require consistent stock removal and professional-grade surface finishing. This G80 grit disc excels at deburring, rust removal, and surface blending on steel, stainless steel, and wood, offering a stable and safe abrasion process; however, users should note that as an 80-grit abrasive, it is optimized for mid-stage smoothing rather than heavy-duty initial grinding or mirror-finish polishing.

FAQs
Can I use this on aluminium?
While it can cut aluminium, the soft metal tends to clog the abrasive flaps quickly; it is best used for steel and wood.
What is the maximum RPM for this disc?
Always verify the RPM rating on the disc label against your angle grinder’s speed; never exceed the disc's marked maximum speed.
Do I need a special guard for this flap disc?
Use the standard guard provided with your angle grinder at all times for safety.
Is G80 the right grit for finishing?
G80 is a medium grit. It is ideal for blending and smoothing but will require a finer grit disc if you need a high-polish finish.
How do I know when the disc is worn out?
When the abrasive flaps are worn down to the backing plate or the cutting performance drops significantly, replace the disc.
Troubleshooting
Disc is vibrating excessively during use
Ensure the disc is seated correctly on the spindle and the locking nut is tightened securely.
Material is burning or discoloring
Reduce your pressure on the tool and keep the grinder moving to prevent heat buildup.
Disc is clogging with metal dust
Clean the disc with a wire brush or dressing stick; if clogging persists, you may be using too much pressure.

Setup, Compatibility & Care
To install the disc, ensure your angle grinder is unplugged or the battery is removed. Place the disc onto the spindle, ensuring the backing sits flush against the grinder flange, and secure it firmly with the locking nut using a standard pin spanner.
Compatibility: This disc is designed for 115mm (4.5 inch) angle grinders with a 22.23mm arbor.
Care Instructions: Keep discs in a dry environment to prevent moisture-related degradation of the backing or bonding agents. After use, inspect the fibreglass backing for cracks or fraying. If you notice significant clogging, use a dressing stick or a wire brush to gently clean the flap surface; never use a damaged or torn disc.
