These wheels boast a 4.5-inch outer diameter and a 7/8-inch arbor size, making them compatible with most standard angle grinders. The blades are designed to operate at up to 13,300 RPM, ensuring fast and effective cutting performance.

The use of aluminum oxide grain enhances the durability and cutting speed, while the double fiberglass mesh reinforcement adds an extra layer of safety and longevity to the blades. With a skinny 0.045-inch thickness, these wheels promise precise, burr-free cuts, making them ideal for working with carbon steel, stainless steel, and various other ferrous metals. This product is also packed with 50 pieces, providing extensive usage before needing a replacement.

On the downside, these cutting discs are coarse grit, which might not be suitable for applications requiring finer finishes. Additionally, users must adhere to safety precautions due to the high operating speeds and potential hazards associated with metal cutting. Given the bulk pack and its specifications, this product is particularly beneficial for professionals or frequent users who need a reliable and efficient solution for cutting metal materials.

This makes them a cost-effective choice for those who frequently engage in metal cutting tasks.

The ultra-thin 1/16-inch design ensures fast, precise cuts with minimal burrs, reducing the need for additional finishing work and minimizing material waste. These discs are versatile, capable of cutting through carbon steel, stainless steel, iron, copper, and various other ferrous metals, which is ideal for diverse metalworking projects. They are compatible with all 3-inch die grinders that operate at speeds up to 25,000 RPM, making them suitable for high-speed applications.

Safety is also a priority, as these discs comply with international safety standards such as EN 12413 and ASM07, though it's essential to wear appropriate protective gear and not exceed the recommended speed during use. On the downside, the ultra-thin design, while beneficial for precision, might make these discs more prone to breaking under excessive pressure or misuse. Additionally, for users requiring blades for larger grinders, these 3-inch discs might not suffice.
