Product Information
Full details
The Norton Vulcan Zirconia Flap Disc (115 x 22mm, 60 Grit) is an essential tool for professional metalworkers and dedicated DIY enthusiasts who require efficient stock removal and precise surface finishing. Its primary advantage is the aggressive cutting speed provided by premium zirconia abrasive, which significantly reduces labor time on heavy-duty tasks like weld bead smoothing. A notable caveat is that the 60-grit texture is a medium-grade abrasive, meaning users seeking a mirror-like finish will require subsequent, finer-grit polishing steps.

FAQs
What is the maximum safe operating speed for this disc?
Always check the label on the disc itself for specific RPM ratings, which are based on industry standards for 115mm discs.
Can this be used on wood?
While zirconia abrasive is designed for metal, it can be used on wood for heavy shaping; however, it will clog much faster than wood-specific abrasives.
Is this disc safe for use on stainless steel?
Yes, zirconia is an excellent choice for stainless steel, provided you maintain a consistent motion to avoid overheating the material.
What does the 60-grit rating mean?
The 60 grit is considered a medium-coarse abrasive, ideal for intermediate grinding where you need to remove material but still leave a relatively decent surface texture.
Do I need a special guard to use this?
You should always use the standard grinder guard provided by your tool manufacturer for safety, regardless of the disc type.
Troubleshooting
The disc is vibrating excessively during use
Ensure the disc is properly centered on the spindle and that the lock nut is tightened evenly.
The disc is glazing over and failing to cut
Reduce the downward pressure being applied; excessive pressure causes heat that glazes the abrasive.
Abrasive flaps are wearing down too quickly
Check if you are using the correct angle of attack; try lowering the angle to keep more of the flap surface in contact with the material.
Pros and Cons
Pros
- High stock removal rate for heavy-duty metal grinding
- Durable zirconia construction outlasts conventional aluminum oxide discs
- Tapered profile allows for precise control on contoured surfaces
- Excellent heat resistance reduces risk of workpiece discoloration
Cons
- Not suitable for fine polishing or mirror finishing
- Requires an angle grinder, not compatible with drills
- 60 grit may be too aggressive for very thin sheet metal
Setup, Compatibility & Care
To install, ensure your angle grinder is disconnected from the power source. Remove the existing disc nut, place the Norton Vulcan disc onto the spindle with the abrasive side facing out, and tighten the locking nut securely with the provided pin wrench.
Compatibility: This 115mm disc is designed for 4.5-inch angle grinders with a standard 22.2mm (7/8 inch) mounting arbor.
Care Instructions:
- Store discs in a dry environment to prevent moisture from degrading the backing or the abrasive bond.
- Inspect for cracks or missing abrasive flaps before every use.
- Keep the disc clean of excessive debris by running it against a piece of scrap metal occasionally to clear the grit, and never exceed the maximum rated RPM of the disc.
