Frequently Asked Questions

Q: What is the main difference between T27 and T29 flap discs?

T27 refers to a flat profile, which is ideal for grinding large flat surfaces, while T29 features a concave or bevel profile, better suited for curved surfaces and contoured workpieces.

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

Yes, they are specifically designed for ferrous metals and Inox (stainless steel), providing an excellent balance of removal and finish.

Q: What does the "100 Grit" specification mean for my project?

A 100 grit is a medium-fine abrasive. It is used for removing lighter scratches, cleaning up weld beads, and preparing a surface for a smooth final finish.

Q: Why is a fiberglass backing plate important?

Fiberglass provides superior structural integrity and safety, preventing the disc from shattering under high RPMs (up to 80 M/S) and ensuring a flat grinding surface.

Q: How do I prevent the disc from clogging when grinding aluminum?

Our discs use a special stearate coating which prevents aluminum particles from sticking to the abrasive grains, ensuring a continuous cut and longer life.

Q: Are these discs compliant with international safety standards?

Absolutely. Our products are manufactured in accordance with EN13743 and are OSA approved, ensuring they meet strict industrial safety requirements.
