Frequently Asked Questions

Q: What is the difference between Type 27 and Type 29 flap discs?

Type 29 is a conical disc, which allows the user to grind at a lower angle, providing better control and a more refined finish compared to the flat profile of Type 27.

Q: Which grit size should I choose for heavy weld removal?

For heavy-duty stock and weld removal, we recommend 36# or 40# grit. For finer cleaning and surface preparation, 60# or 80# grit is more suitable.

Q: Can these Alumina flap discs be used on stainless steel?

Yes, Alumina Oxide is highly effective for stainless steel (Inox), providing a clean removal of oxidation and weld beads without compromising the metal structure.

Q: What is the maximum safe operating speed for the 180mm disc?

The maximum operating speed is 80 M/S, which corresponds to approximately 8,600 RPM. Always ensure your grinder is rated for this speed.

Q: Do you offer custom packaging for wholesale orders?

Yes, we provide OEM services including custom Kraft cartons and palletization to ensure safe transport and alignment with your brand identity.

Q: How do I achieve a mirror-like finish after using a 40# disc?

After using a 40# disc for stock removal, we suggest following up with higher grit discs (80# to 120#) to remove scratches and achieve a smooth final treatment.
