FAQ, See What Others Asked

What is the difference between Type 1 and Type 27 flap discs?
Type 1 discs are flat for maximum cutting depth, while Type 27 discs have a depressed center for better clearance and contour grinding. Both are effective for metal finishing.
Can zirconia flap discs be used on stainless steel?
Yes, zirconia abrasive discs are suitable for stainless steel, offering fast stock removal and a smooth finish without excessive heat buildup.
How do I ensure safe operation at high RPMs?
Always verify the maximum RPM rating of the flap disc exceeds your tool's no-load speed. Use proper wheel guards and PPE for safety.
How do I choose the right grit for my project?
Coarse grit (40) is ideal for heavy stock removal and rough grinding, while finer grits are better for finishing and smoothing surfaces.
What is the best way to store flap discs in India?
Store in a dry, flat place away from moisture and extreme heat to preserve the fiberglass backing and abrasive integrity.
How long does a flap disc last?
Depending on usage, a 10-pack can last from 10 to 20 days for heavy-duty grinding on steel, with proper handling and storage.
