HSS Circular Saw Blades

HSS circular saw blade is widely used for cutting of various metal materials, especially steel pipes, sheets and profiles of thin wall. With more than 20 years technology, production know-how, and advanced production equipment, including NACHI vacuum heat treatment, PVD coating, and a range of advanced equipment and instruments for precision inspection. we can provide high quality HSS circular saw blades with different coatings to meet the cutting needs of various materials.

HSS Material
We have two kinds of HSS material, DMo5 and Co5, to meet our customers different requirements to saw blades.

HSS-DMo5
The material is called M2 high speed steel material in the AISI quality system standard and has a hardness of 64±1HRC, which is widely used for metal circular sawblades. It has good toughness and high wear resistance. HSS sawblades made by this kind of material are used for cutting metal workpieces with low tensile strength (800N/mm2) have good cutting performance, even in the field of cutting stainless steel materials.

HSS-Co5%
This kind of material has higher performance than HSS-DMo5, containing 5% cobalt. The hardness is 65±1HRC. It is called M35 material in the AISI quality system standard. HSS sawblades made by this material are often used for cutting the material that most difficult to cut, such as stainless steel or materials with high tensie strength (800N/mm2) and titanium alloy. The cobalt can significantly improve the cutting service life of the saw blades.

TiN coating This coating can obtain low friction coefficient against metal workpiece. It increases saw blade surface hardness, heat resistance, tenacity, abrasion resistance and anti-adhesion to protect saw blade; It guarantee higher cutting speed and avoid of burr or scraps adhered to the blade tooth. Tts is a cost-effective coating.

VAPO coating VAPO helps to enhance the self-lubricating ability of the saw blade, maintain the toughness of the saw blade during operation, increas the service life of the saw blade, and is suitable for sawing low tensile strength materials. Its affordable coating.

TiCN coating This coating is a multilayer coating with high hardness, low friction coefficient, better wear resistance and anti-adhesion, which can further improve the sawing speed and service life of the saw blade. It has a very significant effect in cutting highly viscous metals such as copper and stainless steel workpieces.

TiAlN coating This coating is specifically used for cutting high alloy steels, stainless steels, very hard steels and abrasive materials such as cast iron, alloys of silicon-aluminium, brass, coper, nickel and titanium. Its high hardness and low thermal conductivity allow the saw blade to be used for high speed cutting, even in conditions of poor lubrication or misting.
