Fotybei Cutting Discs
Score: 78/100Rankings

The Dremel MM485B is a high-performance carbide flush-cutting blade designed for oscillating multi-tools, offering exceptional durability and speed in tough materials. Its primary limitation is incompatibility with plastics and ferrous metals, restricting its use to specific renovation tasks. It is best suited for professional renovators and contractors who require long-lasting blades for hard materials like tile and galvanized screws.

The Fotybei Cutting Discs kit is a versatile accessory set featuring diamond, HSS, and resin blades for diverse DIY tasks. Its main limitation is the lower maximum RPM and thin blade profile, which restricts heavy-duty applications. It is best suited for hobbyists and jewelers needing precise cuts on soft-to-medium materials.
