Product Information
Full details
The Spyder Cutting & Grinding Disc Set is engineered for metalworkers, fabricators, and serious DIY enthusiasts who require aggressive material removal and precision cutting. These aluminum oxide wheels deliver rapid cut rates on mild steel, stainless steel, and cast iron, making them an essential utility for heavy-duty metal prep. While highly effective, users must note that the 3.18mm thickness is optimized for balance between cutting and grinding, meaning it may not provide the ultra-thin, burr-free finish of specialized slicing discs.

FAQs
Can I use these discs on wood or plastic?
No. These discs are specifically designed for ferrous metals and can cause fire or clog immediately if used on softer materials.
What is the maximum RPM for this disc?
Always check the speed rating printed on the disc label; it must meet or exceed the maximum RPM of your angle grinder.
Is this a dedicated cutting or grinding disc?
It is a hybrid disc. It is designed to handle both tasks effectively due to its 3.18mm thickness.
How should I store these discs?
Store them flat in a dry environment, away from extreme humidity and direct heat.
Do I need special PPE?
Yes, you should always wear impact-resistant safety glasses, a face shield, heavy-duty gloves, and a dust mask or respirator.
Troubleshooting
Disc is vibrating excessively during use
Check that the disc is perfectly centered on the flange and the lock nut is tightened securely.
Disc is cutting slowly or glazing over
The abrasive may be clogged. Apply the disc to a piece of scrap metal briefly to 'dress' the surface and expose fresh grit.
Disc edge is chipping prematurely
Ensure you are using the disc at an appropriate angle and avoid side-loading the edge while cutting.
Pros and Cons
Pros
- Aggressive material removal for fast work
- Excellent durability on ferrous metals
- Dual-purpose design for both cutting and grinding
- Industry-standard dimensions for wide compatibility
Cons
- Not intended for non-ferrous materials like aluminum or copper
- Thicker profile creates more kerf compared to dedicated thin-cut wheels
- Produces significant sparks requiring proper PPE
Setup, Compatibility & Care
To ensure safety and optimal performance, always verify that your angle grinder's guard is properly positioned and secured before installing the disc. Ensure the tool is unplugged or the battery is removed during the installation process. Slide the disc onto the 22mm spindle, ensuring the backing flange is centered correctly, and tighten the lock nut using the appropriate pin wrench. Always perform a test run for at least 30 seconds in a protected area before applying the disc to your workpiece. For care, store these discs in a cool, dry place; moisture can compromise the bonding agent of abrasive wheels, leading to premature breakdown during use.
