Upgrade your cutting capabilities with the Mywish 50-Piece Professional Jigsaw Blade Set. Unlike standard sets, this kit focuses on superior material quality to deliver ruggedness and longevity. The metal-cutting blades are engineered from M2 High Speed Steel (HSS), making them tough enough to handle thin metal sheets (1-3mm) and medium-thickness plates (2.5-6mm) without dulling prematurely.For woodworking tasks, the blades are constructed from SK5 High Carbon Steel (HCS), known for being significantly more durable than standard CRV steel. This ensures that whether you are making fast straight cuts with the T144D or intricate curve cuts with the T101AO, the blades remain sharp and resist bending.The set includes a generous assortment of 10 metal blades and 40 wood blades to cover every phase of your project. Each blade features a universal T-shank design, compatible with most jigsaws on the market today, providing a secure grip and enhanced cutting experience.
