Cobalt-Containing Wear-Resistant High-Speed Steel Machine Saw Blades, Specialized for Cutting Stainless Steel Tubes, Circular Saw Blades, and High-Speed Steel Milling Cutters
Zhuhai Daou Tools Co., Ltd. has launched cobalt-containing wear-resistant high-speed steel machine saw blades. Through VAPO nitriding coating and high-temperature oxidation heat treatment, an oxide layer with a thickness of approximately 5–10 microns forms on the surface. This layer achieves a surface hardness of about 800–900 HV and a friction coefficient of 0.65. The smooth surface of the saw blade enhances self-lubrication, reducing the risk of jamming during material cutting.

Jingshang provides a variety of high-speed steel saw blades, including M2, W5, W6, and M42 grades, designed for compatibility with tube cutting machines. These blades are suitable for cutting metal pipes such as stainless steel tubes, galvanized pipes, and iron pipes, allowing for 90-degree or 45-degree angle cuts with smooth, burr-free surfaces.

The Secret of M42 Material Band Saw Blades: Crafting Tools for Efficient Processing – Machine Saw Blades – Taobao Goods Network
This article introduces the application of bimetal M42 material band saw blades in mechanical processing. The base is typically made of high-carbon steel or alloy steel, while the working layer is composed of high-speed steel. The addition of cobalt enhances heat resistance and hardness. These saw blades are widely used in fields such as aerospace, automotive manufacturing, and mold processing. They can cut materials like high-strength aluminum alloys, titanium alloys, and high-strength steel plates, and also perform exceptionally well in woodworking and composite material cutting.
