The silicon carbide abrasive offers hardness and durability for use with titanium, fiberglass, plastic, and masonry. It provides a high-quality surface finish on hard-to-machine materials. Applications include surface grinding, edge grinding, and removal of marks from concrete. The disc has a flat surface and is commonly used with 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.

I guess I will try some cheaper flap disks in a few weeks to compare. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/83799523-pferd-polifan-sg-abrasive-flap-disc-type-27-round-hole](https://www.desertcart.hr/products/83799523-pferd-polifan-sg-abrasive-flap-disc-type-27-round-hole) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-16*
