Got a Fein oscillating MultiMaster? Then you know you need quality blades. This 5-pack of Fein HSS (High-Speed Steel) saw blades is built for serious cutting. They have a segmented, metal tooth design that's perfect for cutting through thin sheet metal (up to about 1/16 inch thick), plastics, fiberglass (GFRP), wood, glazing compound, brass, and bronze. The StarLock mounting system ensures a secure, quick-connect fit to your Fein tool without any wobble. The 3-11/32 inch diameter and segmented teeth are great for getting into tight corners and making precise cuts with minimal overcut – perfect for detailed work in remodeling, auto repair, or metal fabrication. These are professional-grade blades designed to last longer and perform better than generic brands. If you use your Fein tool for anything beyond basic wood, having a pack of these dedicated metal/plastic blades is a smart move. They fit Fein Cordless MultiMaster AMM and standard MultiMaster MM models.
