Product Information
Full details
The JCB 115mm 36 grit flap discs are designed for metalworkers, automotive technicians, and DIY enthusiasts who require aggressive stock removal and heavy-duty surface preparation. These discs offer exceptional durability and versatility across a wide range of materials, though their coarse 36 grit profile makes them less suitable for fine finishing tasks where a smooth, polished surface is required.

FAQs
Are these discs suitable for wood?
Yes, they can be used for aggressive shaping and removal on wood, though they will leave a coarse finish.
Do I need a specific grinder for these?
These discs fit any standard angle grinder that uses a 115mm diameter disc and a 22.23mm bore spindle.
Can I use these on stainless steel?
Yes, they are highly effective for grinding and blending stainless steel surfaces and weld seams.
What is the maximum speed rating?
Always follow the RPM rating specified on the disc label and ensure it matches or exceeds your grinder's maximum RPM.
Are these discs washable?
No, these are dry-use abrasive discs and should not be exposed to water or cleaning solvents.
Troubleshooting
Excessive vibration during use
Ensure the locking nut is fully tightened and the disc is centered correctly on the spindle.
Disc is wearing down too quickly
Reduce the amount of downward pressure applied; let the grit perform the cutting action.
Surface being gouged
Maintain a shallower angle between the disc and the workpiece; do not hold the grinder at a 90-degree angle.
Pros and Cons
Pros

- Highly durable polyester construction
- Standardized fit for 115mm angle grinders
- Effective on a wide variety of metals and alloys

Cons
- 36 grit is too coarse for final polishing

Setup, Compatibility & Care
To mount the disc, ensure your angle grinder is disconnected from the power source. Depress the spindle lock button, remove the outer locking nut, place the JCB flap disc onto the spindle, and tighten the locking nut securely. Always ensure the 115mm guard is properly attached to your grinder before operation. Regarding care, these discs are consumables; however, to maximize lifespan, store them in a cool, dry environment to prevent moisture from degrading the abrasive bond. Avoid dropping the discs, as a cracked fibreglass backing plate can lead to mechanical failure during use.
