Louver blades are commonly used consumables for metal polishing, deburring, and weld cleaning.You need to pay attention to the following points when buying：
- Look at abrasives: alumina is cost-effective and suitable for ordinary steel; zirconium corundum has good wear resistance and long life, and is suitable for stainless steel and high-strength steel.
- Look at the size: the commonly used diameters are 115mm, 125mm, 150mm, and 180mm, which need to match the specifications of the angle grinder.
- Look at the particle size: choose P36-P40 for coarse grinding, P60-P80 for medium grinding, and P100-P120 for fine grinding and polishing.
- Look at the backplane: the flat backplane is suitable for large-area polishing, and the tapered backplane is suitable for weld and corner cleaning.
- Look at the speed: Be sure to confirm that the maximum speed of the product is not lower than the speed of the angle grinder to ensure safety.
The correct choice of louver blades can not only improve the grinding efficiency, but also reduce the overall cost.
