Merryland Flap Disc 4.5" 40 Grit T29 for Metal 🛠️
Description:
This 4.5 inch flap disc for angle grinder delivers aggressive material removal with longer life, making it suitable for heavy deburring and shaping of metal parts. It combines a cone-shaped T29 flap layout with coarse 40 grit zirconia to tackle stainless steel, iron, and thick steel panels quickly while keeping vibration low.
Key Points
The disc is built with refined European abrasive paper and blue zirconium corundum for sustained cutting performance. It uses a reinforced fiberglass backing that helps absorb vibration and reduces marking during use. Safety certifications are included, with a maximum rotational speed rated at 13300 RPM according to EN 13743 and tested to MPA standards. ⚙️🛠️
The 40 grit surface is tuned for heavy stock removal and edge blending rather than fine polishing, so it removes weld seams and shapes contours efficiently. T29 flap wheels are particularly adaptable on curved surfaces and contoured edges because of their angled flaps, which conform better than flat discs. 🔩

Usage Recommendations
Attach the disc to standard angle grinders and grinding machines that accept a 22.23 mm arbor. Work with steady, moderate pressure and keep the disc moving across the workpiece to avoid glazing and excess heat build-up. For best results on stainless steel maintain light passes and allow cooling intervals when removing thick weld material.
Consider using personal protective equipment because coarse grits generate more sparks and heavier debris. This flap disc performs strongly for heavy grinding and shaping, but it may not deliver a mirror finish, so follow up with finer grits if surface refinement is required.
