Shree Engineering Works

In general, the best sawzall blades for cutting metal have a higher TPI (Teeth Per Inch) and are bi-metal or carbide tipped. The right TPI and blade material depend on the type of metal being cut and its thickness. Cutting thinner metals, including sheet metal, requires a finer cut. Use 18-24 TPI bi-metal blades.

We use in-house volume hardening, straightening, and long-time tempering to achieve hardness from 55-62 HRC as per drawing, followed by first-class grinding and sharpening for smooth and proper cutting.

Most shear blades for the metal fabrication are made from tool steel, with some being made from high chrome or high carbon steel. Scrap shear blades are often made from low alloy steel. We produce knives and blades from a variety of these materials designed to suit your application.

The common CNC hydraulic shearing machine blade material of low alloy tool steel are: 6Crw2sI, Cr5molv, 9CrSi, Cr12MoV, etc. The heat treatment hardness of the blade is in the range of HRC58-62 degrees. It is specially used for cutting stainless steel hot rolled plate, medium and thick plate.
