What is the HSS high speed steel saw blades?
A saw blade is a steel piece with a cutting edge similar to a hand saw. High speed steel saw blade is a type of saw blade composed of high amounts of carbon (C), tungsten (W), molybdenum (Mo), chromium (Cr), vanadium (V) and other elements. After heat treatment, it has high thermal hardness. Due to the high cutting temperature of high-speed steel, even when it reaches over 600 ℃, the hardness still does not significantly decrease. The cutting speed of saw blades made from it can reach over 60 meters per minute, hence the name high-speed steel saw blade. high speed steel saw bit.
High speed steel saw blades can be divided into ordinary high-speed steel saw blades and high-performance high-speed steel saw blades according to their chemical composition; According to the manufacturing process, it can be divided into melted high-speed steel saw blades and powder metallurgy high-speed steel saw blades.
High speed steel saw blade, also known as wind steel saw blade or white steel saw blade. An alloy steel saw blade containing a high amount of carbon (C), tungsten (W), molybdenum (Mo), chromium (Cr), vanadium (V) and other elements. High speed steel raw materials have high thermal hardness after production processes such as cutting, forging, annealing, semi-finished products, quenching, and gear cutting. When the cutting temperature reaches over 600 ℃, the hardness still does not decrease significantly, and the cutting speed of the saw blade can reach over 60 meters per minute, hence its name.
Classification of high speed steel saw blades
High speed steel saw blades can be divided into ordinary high-speed steel and high-performance high-speed steel saw blades according to their chemical composition. According to the manufacturing process, it can be divided into melted high-speed steel and powder metallurgy high-speed steel saw blades.
Instructions for using high-speed steel saw blades
In order to maximize the performance of the saw blade, it must be used strictly in accordance with the specifications:
- Different specifications and uses of saw blades have different blade angles and substrate forms, so try to use them according to their corresponding situations;
- The size and positional accuracy of the spindle and clamp plate of the equipment have a significant impact on the effectiveness of use, and should be checked and adjusted before installing the saw blade. The factors that affect the clamping force and cause displacement and slippage on the contact surface between the clamping plate and the saw blade must be eliminated;
- Always pay attention to the working condition of the saw blade. If any abnormalities occur, such as vibration, noise, or material feeding on the processing surface, the machine must be stopped and adjusted in a timely manner, and polished to maintain peak efficiency;
- When grinding the saw blade, do not change its original angle to avoid sudden heating and cooling of the blade head. It is best to seek professional grinding
- The temporarily unused saw blade should be hung vertically to avoid prolonged flat placement, and should not be stacked on top of it. The blade head should be protected and not collided.
The use of high-speed steel saw blades
Application of high-speed steel saw blades: Ordinary high-speed steel saw blades are mainly used for narrow and deep groove processing or cutting of medium hard and below metal materials such as steel, iron, copper, aluminum, etc. It can also be used for non-metallic milling processing. High performance high-speed steel saw blades are mainly used for milling difficult to cut materials (high-strength steels such as heat-resistant steel and stainless steel)
Characteristics of high-speed steel saw blades:
The high-speed steel saw blade grinding machine can be repeatedly used to grind the blade teeth. Improve production efficiency and reduce costs.
Applicable Machinery of High speed steel saw blades
High speed steel saw blades are suitable for various domestic, imported automatic or semi-automatic and hydraulic pipe cutting machines, metal circular saws, pipe cutting machines, pipe processing machinery, sawing machines, milling machines, etc.
High speed steel saw blade tooth profile
BW tooth type is the most widely used, followed by A, B, and C tooth types, while BR and VBR tooth types are less commonly used in China.

Other types usually require customization. We are a factory with 20 years of experience in producing high-speed steel saw blades. We can customize various types of saw blades according to customer needs.
Installation requirements for high speed steel saw blades
- Before installation, ensure that the equipment is in good condition and that there is no deformation or radial jump in the spindle.
- Before use, it is necessary to check whether the saw blade is damaged, whether the tooth profile is complete, or whether there are any other abnormal phenomena.
- During assembly, ensure that the direction of the saw blade arrow is consistent with the rotation direction of the equipment spindle.
- When installing the saw blade, the axis, chuck, and flange should be kept clean. The inner diameter of the flange should be consistent with that of the saw blade to ensure a tight fit between the flange and the saw blade. Tighten the nut.
- Before starting the equipment, ensure safety and perform a jog idle to check if the equipment is turning correctly and there is no vibration. After installing the saw blade, it should first idle for a few minutes without slipping, swinging, or jumping before resuming normal operation
