Product Description

The Pferd Polifan SGP Zirkon-Special type 27 zirconia alumina abrasive flap disc has a phenolic resin backing for reinforcement and an unthreaded round hole for attachment to grinding tools. The zirconia alumina abrasive is self-sharpening and more durable than aluminum oxide, which makes it suitable for fast material removal rates and aggressive grinding on steel and stainless steel. The disc produces a high-quality, consistent finish with low risk of glazing. Applications include surface grinding and weld finishing. It is free of iron, sulphur, and chlorinated fillers. The disc has a flat surface and is commonly used with high-output angle grinders. It has an unthreaded round hole for attachment to the grinding tool. The tool's arbor goes through the central hole in the disc for fastening.

Abrasive flap discs are made from overlapping pieces of coated abrasive attached to a hub. They help reduce finishing time and cost by grinding and finishing in the same step, such as when removing a weld bead and smoothing the workpiece around the weld. Flap discs are coated, meaning an adhesive is used to attach the abrasive grains to a backing of paper, plastic, or cloth. The action of a flap disc is much like that of a sanding disc: the grinding or polishing occurs on the face of the disc. They are used for a variety of applications from shaping a part to fine finishing, depending on the grit size. Low grit numbers like 40 are coarse (with fewer, larger grains) and remove excess material and shape parts. High grit numbers like 400 are fine (with more, smaller grains) and help create a smooth surface finish.

Pferd manufactures abrasives and cutting tools for grinding, finishing, and cutting. Founded in 1799 in Germany, Pferd has its U.S. headquarters in Leominster, MA, and meets International Organization for Standardization (ISO) 9001 standards.
