The Eclipse Plus 30 Flexible BiMetal High Speed Steel Hacksaw Blade is a virtually unbreakable blade for superb cutting performance, wear resistance and safety. A combination of an M2 high speed ground cutting edge, electron beam welded to a flexible alloy back gives a level of cutting power and flexibility that is far superior to edge hardened or conventional flexible blades. The unique ground tooth profile of the Plus 30 blade produces a faster and more aggressive cutting action that requires less effort and is more efficient than a standard blade. Cuts through all types of metals including alloy and stainless steel. Box of 100, 24 tpi
