Description
Fair quality, budget price
Our Ceramic Flap Disc is designed to deliver strong grinding performance and reliable stock removal at an affordable price. It combines the high-performance grinding power of ceramic abrasive grain with good durability, making it a practical choice for everyday grinding and heavy-duty metalworking applications on steel, stainless steel, and other hard metals.
This Ceramic Flap Disc provides an aggressive and consistent cut for high-pressure weld removal, edge grinding, beveling, and chamfering in metal fabrication. Its self-sharpening grain with a top coating layer helps maintain grinding performance throughout the life of the disc while providing cooler grinding and excellent value for regular shop and fabrication work. Designed for professional and general-purpose metalworking, this Ceramic Flap Disc provides a cost-effective ceramic option for applications where good cutting performance, durability, and overall value are important.
Suitable for the following materials:
- Carbon Steel
- Stainless steel
- Titanium
- High speed and tool steels
- Alloyed Steels
- Sheet metal
- Non-Ferrous metals
Depending on the grinding angle and surface to be ground, Flap Discs are available in two types:
Type 27 – has flat surface and can achieve maximum efficiency when applied at a work angle of 0-15 deg angle. These discs are the most suitable for grinding flat surfaces.

Type 29 – has a slightly conical surface, for grinding at 10-25 deg angle. These discs are the most suitable for grinding contoured surfaces.
