These 28mm blades are made from high quality SKS-7 Carbide Tools Steel so they stay sharper and last longer.
Pre-lubricated to prevent rusting and corroding.
Fits all 28mm rotary cutters.
Free snap case included for blade storage.
Note: Our personal experience with these blades is, they last longer, fit the same and are much more inexpensive than the Name Brand Blades.
