Irwin Bimetal Snap Off Blades 18mm – 8pc Pack

Bi-Metal snap blades are produced through a patented process of combining two types of metal, spring steel and high speed steel.

Spring Steel allows the blade to bend without accidentally breaking.  It also ensures that the blade snaps cleanly on the score every time.

High-Speed Steel Delivers a hardened cutting edge that stays sharp 3x longer than traditional carbon blades.
