The Milwaukee 48-00-4091 Ice Edge Sawzall blade is specifically designed to handle the toughest metal-cutting applications for HVAC, automotive, plumbing, ship building, salvage and more. This next-generation blade features a bi-metal construction with 8-percent cobalt, making the Ice Edge a flexible alternative to other reciprocating blades.

Milwaukee's cryogenic heat-treat process induces a permanent change in the microstructure of the high-speed steel cutting edge, and because it penetrates to the full depth of the blade, this treatment improves the hardness, wear-resistance, and dimensional stability of the blade.
Advantages over TiN (Titanium) Blades
- Cryogenic heat treatment offers a permanent change to blade properties: With TiN coating, the wear rate is accelerated by high temperatures generated during cutting. The Ice Edge blades are less susceptible to high-temperature damage than TiN blades.
- Ice Edge blades receive uniform treatment: TiN coatings are deposited by the PVD (Physical Vapor Deposition) method. PVD does not produce a strong bond with the HSS edge wire since PVD is a low-temperature process. Thus, TiN coating easily wears out. It is also difficult to get the uniform coating on the teeth with the PVD process--given the complexity and small size of the teeth--so the full benefit of the TiN coating is not realized on reciprocating blades. Unlike TiN coating processes, the Ice Edge blade treatment results in a uniform, permanent change to the entire blade structure.
This completely redesigned reciprocating blade optimizes metal cutting with precision-ground teeth, a radiused back face that increases tooth strength, and many other must-have features.
