When purchasing abrasive tools, you may often confuse angle grinders and flap discs. Although both tools can be used for grinding, they are very different.
the difference between angle grinders and flap discs
1. Different shapes
Angle grinders are high-speed grinding tools made of abrasives such as brown corundum, resin as a binder, and glass fiber mesh. Angle grinders are cymbal-shaped and thicker than flap discs. Small-sized angle grinders are generally 100mm, 125mm, 150mm, etc., and large-sized ones are most commonly 180mm, 230mm, etc.
The flap disc is composed of blades and a base. The base of the flap disc has many materials, such as nylon, plastic, mesh, steel paper, etc. In order to meet different grinding needs, the blade material is also a variety of. The parameters of the flap disc are divided into the number of pages and the number of meshes. The most commonly used diameters are generally 100mm and 125mm.
2. Different characteristics and uses
The maximum speed of the angle grinder can reach 80m/s. It has strong tensile, impact and bending resistance, and high grinding efficiency. It is widely used in the grinding and rust removal of various metal materials and non-metallic materials, which is fast and economical. It has always been in the automotive, shipbuilding, machinery manufacturing and construction industries, and it is also very convenient to install and use.
Flap disc is composed of multiple gauze pages glued to the tray in a fan-shaped stacking arrangement, so it has strong elasticity, high tensile and bending strength, good heat dissipation, and low noise when grinding. The flap disc is suitable for grinding and polishing in industries such as stainless steel, metal, wood and marble, especially for the grinding effect of metal and stainless steel welds and stamping flash. Zircona fused alumina is particularly suitable for stainless steel processing. It can be used with resin angle grinders for better results.
When purchasing and operating grinding discs, you can choose these two types of grinding discs according to the grinding materials and grinding effects, so as to maintain good grinding efficiency during grinding and save costs!
