M2 (DMo5) HSS Circular Cold Saw Blade and High Speed Steel Cold Saw Blade with

With extremely high micro hardness and thermal hardness, this coating is suitable for tools with high thermal tension coating, especially in the processing of high hardness, austenitic stainless steel, and duplex stainless steel for both finish and rough machining. It also offers good heat shock resistance, making it an ideal choice for fast interrupted cutting applications. Widely used in carbide turning, milling, drilling, and gear cutting tool coating.

The most typical and common PVD super hardness coating, mainly used for turning, milling, drilling, and gear cutting tool wear-resistant coating, as well as injection molding anti-connection. It improves lubrication and wear protection.

TiCN offers higher hardness than TiN but a lower coefficient of friction. It is used for processing materials with abrasive or strong toughness characteristics, such as cast steel, copper alloy, or aluminum alloy.

An uncoated saw blade used for cutting general non-ferrous metals such as brass and aluminum.

VAPO nitriding coating is produced through high temperature oxidation. The color is dark black. After the chemical element Fe3O4 undergoes precise special heat treatment, an oxide layer (Fe3O4) is formed on the surface with a coefficient of 0.65. This saw blade has good surface smoothness, which helps enhance the self-wetting ability of the blade and can avoid the phenomenon of the blade being stuck by the material to a certain extent. Used for cutting general materials. Due to its mature processing technology and cost-effectiveness, it is a widely used product in the market.

After PVD nitriding treatment, the saw blade coating thickness is approximately 2–4 microns, the surface hardness is about 2200–2400 HV, the friction coefficient is 0.55, and the cutting temperature is 520°C. This saw blade can greatly improve blade service life. To make full use of its characteristics, the cutting speed should be increased to reflect its value. The main purpose of this coating is to make the blade more resistant to cutting. For cutting general materials, its excellent performance can effectively increase cutting speed and reduce loss.

This coating is particularly resistant to bonding, corrosion, and oxidation. Saw blade coating thickness is 2–4 microns, surface hardness is 1800 HV, cutting temperature is below 700°C, and the color is metallic gray. Highly recommended for cutting copper and titanium. The coating process has no impact on the environment. Suitable for cutting copper, aluminum, and other materials, with high coating density and surface hardness, as well as the relatively low friction factor of all coatings.

Saw blades treated with multi-layer PVD coating have a very low friction coefficient. The surface hardness is about 3000–3300 HV, the friction coefficient is 0.35, and the oxidation temperature is 450°C. The blades provide a very smooth cutting surface and are more resistant to wear. Recommended for cutting materials with high cutting and feed speeds and tensile strength over 800 N/mm², such as stainless steel, and for use in particularly harsh working conditions.

AlTiN is a new multilayer composite anti-wear coating. The coating thickness is 2–4 microns, the surface hardness is 3500 HV, the friction coefficient is 0.4, and the cutting temperature is lower than 900°C. Materials with high cutting speed and feed speed and cutting tensile strength over 800 N/mm² (such as stainless steel) are recommended for use under particularly harsh operating conditions such as dry cutting. Due to the toughness and good physical stability of aluminum titanium nitride coating itself, the saw blade is more wear-resistant and suitable for cutting all steel. Its low coefficient of friction and low thermal conductivity make it especially suitable for high speed and high temperature dry cutting.

This coating is suitable for more demanding wear resistance requirements. Recommended for cutting materials with tensile strength over 800 N/mm². The coating thickness is 3 microns, the friction coefficient is 0.45, the oxidation temperature is 875°C, and the surface hardness is about 3300–3500 HV. Suitable for cutting high strength steel such as stainless steel, and can also be used for cutting soft materials such as cast iron, aluminum alloy, brass, and copper. Due to its low coefficient of friction and low thermal conductivity, it is especially suitable for high speed and high temperature dry cutting.
