4-1/2" Zirconia Flap Disc – Type 27 Flat Grinding, P40 Grit

These 4-1/2" zirconia flap discs are designed for aggressive blending, weld finishing, and controlled grinding on flat metal surfaces. Built with high-density zirconia abrasive grain, they deliver fast material removal, reduced heat buildup, and extended disc life in demanding welding and fabrication applications.

The Type 27 flat design provides maximum surface contact, making these flap discs ideal for smoothing welds, surface preparation, and light stock removal where control and finish quality matter. Rated for high-speed operation, they are engineered for safe, consistent performance on standard angle grinders.
